  • If Uraniums atomic number is is 92 and it has 10 neutrons, how many protons does it have?
    If Uraniums atomic number is is 92 and it has 10 neutrons, how many protons does it have?
    The answer is 92 because the atomic number reveals information about the protons and electrons in the element. Do not get this confused with the atomic mass. Neutrons in an atom are found by subtracting the number of protons to the atomic mass in the element. (Which is 82, and is also scientifically impossible.)

  • Why is the electron a fermion?
    Why is the electron a fermion?
    Two types of fundamental particles exist in the world fermions and bosons. Fermions particles have mass, spin (angular momentum), and charges. Bosons do not have mass and have an angular spin that is a whole integer (positively or negatively charged 1, 2, 3…). Fermions, on the other hand, have mass and their angular spin is in half integers (positively or negatively charged 1, 2, 3…).   The Pauli Exclusion Principle, which applies to fermions only, states that no two fermions can occupy the same quantum state (be in the same place at once) as opposed to bosons, which can occupy the same quantum state. Electrons also have the same properties as fermions in that they have mass, angular momentum, and charges. The angular momentum for electrons is nh/2pie (according to Bohr atom), which equates to a half integer spin similar to fermions. Furthermore, electrons belong to a family of particles called leptons, the basic building blocks of matter (elementary particles.) Fermions include lepton particles. Therefore, for all of the reasons above, electrons are fermions.

  • How is an electron neutrino different from a normal neutrino?
    How is an electron neutrino different from a normal neutrino?
    To understand the differ nice between en electron neutrino and a normal neutrino, it must first be understood what a neutrino is. A neutrino is a subatomic particle that is neutral. It’s mass is zero, has a half-integer spin, and rarely interacts with matter. When a subatomic lepton particle, hitch has no electric charge, joins an electron, it creates a first generation of leptons known as electron neutrinos. Thus, the main difference is that an electron neutrino is a type of neutrino that has a charge, while a typical neutrino is neutral.   However, all neutrinos have similar properties and normal neutrinos and electron neutrinos each have an antineutrino and antielectron neutrino counterpart. Millions of neutrinos constantly pass through your body. It was recently found that neutrinos actually do have a small mass; less than one millionth of that of an electron. Lastly, neutrinos travel slightly less than the speed of light, so they cannot be detected.

  • Why are electrons weightless?
    Why are electrons weightless?
    They say that the electron is weightless because it is so small that it can barely be seen. There are also other reports stating that perhaps it is not true that electrons exist because there are not enough details that will show that they are actually there.   Electrons have not been photographed and people do not have the right tools in order to magnify atoms to hopefully show the electrons, protons, and neutrons. Yet, they are generally weightless because they are usually attracted to protons and they may go around the nucleus. When this occurs, the only weight that they will have is their combined atomic weight.

  • Why can't an electron's movement in a quantum field not be detected?
    Why can't an electron's movement in a quantum field not be detected?
    According to the Heisenberg Uncertainty Principle, the main reason why it will be hard to detect the movement of the electron in a quantum field is that the electrons do not have their own specific locations. They also do not have a direction of motion so trying to understand their movement will not be necessary and will not provide any definite results.   It also does not help that the electrons are all moving around in all different directions and doing different motions at the same time. The Uncertainty Principle was proposed back in 1927 and a lot of scientists and professionals still refer to this when they are studying electrons and anything related to electrons.

  • What is the function of electrons in cathode ray tubes?
    What is the function of electrons in cathode ray tubes?
    Cathode ray tubes are technology used to ultimately procure a picture. A cathode ray tube takes an incoming electronic signal and turns it into an electron stream, which creates an image he combined with certain substances. More specifically, negative electrons are deflected by the cathode to positively charged plates. The larger the picture, the greater the deflection; as the cathode ray moves horizontally across a scene. Sound familiar?   Cathode ray tubes are the most common technology used in computer monitors and televisions. For this reason, the signal needs to be constantly refreshed even if the colors don’t change. Cathode ray tubes are a less expensive alternative to LCD or plasma screens. They are also used in various medical monitors and oscilloscopes. So, electrons are not just a part of cathode ray tubes, they are everything needed to make it functional. Without electrons, cathode ray tubes would be useless and have nothing to produce.

  • What is an electron bubble?
    What is an electron bubble?
    In a cryogenic gas or liquid, such as neon or helium, an electron bubble is the empty space around a free electron. Electron bubbles are very small, measuring approximately 2nm in diameter when at atmospheric pressure. There is also theoretical probability that a 2s electron bubble exists. This type of bubble has a spherical wave function but the shape when stable is nonspherical.  The 2S electron bubble is supposed to reflect a unique morphological instability when placed under intense, ambient pressure.   The electron bubble theory was developed when it was realized that below a certain temperature, the mobility of electrons drops drastically.  Otherwise, in noble gasses at room temperature, typically electrons move about freely. That is why at such low temperatures, electrons actually do not move about freely and they form small ‘bubbles’ around themselves instead. The size of an electron bubble varies according to three main factors. Those factors are: the amount of confinement, surface tension, and pressure-volume.

  • What is the mass of Aluminum if it has an atomic number of 13 and has 14 protons?
    What is the mass of Aluminum if it has an atomic number of 13 and has 14 protons?
    If your element had 14 protons, it would be silicon, not aluminum. As soon as you add that one extra proton, it becomes an entirely different element, therefore, this question is invalid.

  • What is the charge on an electron?
    What is the charge on an electron?
    The elementary charge on an electron is at 1.60217662 × 10-19 coulombs. Some say that since an electron has a negative charge, there should be a negative sign before the actual charge. The charge of protons and electrons are always the same but the charges will be different.   It will always be negative for the electron and a positive charge for the proton. The neutron is obviously neutral which means that it will not have any charge. The electron is considered to be important because it carries a lot of energy especially the electrons that can be found on the outer layer of atoms. If electrons do not exist, there are a lot of processes and items that will cease to exist.

  • Why do electrons have antisymmetric wave patterns in quantum fields?
    Why do electrons have antisymmetric wave patterns in quantum fields?
    A few things are known about quantum fields. One; electrons are fermions, in which fermions cannot exist in the same state at the same time. And two; this is because particles with antisymmetric wave patterns cannot exist in the same state. According to quantum field theory, electrons must have antisymmetric wave patterns in quantum fields because if the fields are annotated as spin-0 and no spin- ½ this shows that electrons must have antisymmetric wave patterns otherwise there would be an infinity number of negative energy states.   This concept is explained in the Peskin and Schroder proof, and by using the Lorentz invariant. It all comes down to the mathematical symmetric equations, such as the C symmetry. In short, electrons must have antisymmetric wave patterns, since their bison counterparts are symmetric. Bosons can occupy the same state, while fermions cannot. This balance is required to establish the behavior of an atom

  • How did Donald Kerst accelerate electrons?
    How did Donald Kerst accelerate electrons?
    After several failed attempts before him, Donald Kerst successfully accelerated electrons in 1940 at the University of Illinois. Kerst was able to accelerate the electrons using a betatron. A betatron sends electrons into high speed, circular orbit, using the electric field created by a varying magnetic field. Kerst’s success was due to careful analysis and detailed planning. He analyzed the dynamics of orbits and created detailed designs for the magnet structure, vacuum system, and power supply. The first betatron Kerst created produced 2.3-MeV electrons, while successive betatrons could produce up to 300-MeV electrons.   This is such a significant event in the course of technology because all previous accelerators were cut and dry, while Kerst’s was scientifically engineered and supported. Today, modern betatrons are used for high energy x-rays and other applications. All accelerators that are used today have a foundation in Kerst’s work. Lastly, all degrees on the physics of acceleration have been completed under Kerst’s direction.
