    What will happen to a non-metal atom if it combines with a metal atom?
    A nonmetal atom or element does not have much or any metal in it. These types of elements have certain characteristics about them compared to the metals that are on the periodic chart. Nonmetals can be vaporized in simple ways and they can conduct heat. On the periodic table, there are 17 elements that are considered to be nonmetals. They are hydrogen, xenon, radon, krypton, fluorine, nitrogen, helium, oxygen, neon, argon, and chlorine. These are the nonmetals that are gases. The other six elements that are nonmetals include sulfur, selenium, bromine, carbon, radon, phosphorus, and iodine. These are all solids except bromine which is a liquid. If you combined a nonmetal atom with a metal atom, the atom would become larger and there would be more electrons.

  • Which electron configuration could represent a strontium atom in an excited state?
    Which electron configuration could represent a strontium atom in an excited state?
    Each element has an electron configuration that corresponds to its proton number. These electrons are responsible for the reactivity of the element. Strontium is an alkali metal and alkali metal and is one of the most reactive elements on earth. It has a normal configuration with two valence electrons in its outer shell. However, as the element is excited, one of the eight electrons bump into the valence shell. Ultimately, the new configuration becomes 2-8-18-7-3. This is how it binds to other atoms and creates strong compounds. It has many shells in its atoms, so the outer electrons are further away from the nucleus. This is what allows this phenomenon to occur.

  • What is the difference between NAD and FAD?
    What is the difference between NAD and FAD?
    You may not be aware of what NAD and FAD are. There are both known to be electron carriers, and they are expected to do many different roles. FAD stands for Flavin Adenine Dinucleotide whole NAD stands for Nicotinamide Adenine Dinucleotide. NAD is known to be found in almost all living beings and is needed by the body, while FAD is known to contribute to a lot of metabolic reactions that are available. The main difference between the two is the number of hydrogen atoms that can accommodate. FAD can get up to two hydrogens, but NAD can only accommodate one. These two are both very useful in the Krebs Cycle.

  • What does the quantum mechanical model state?
    What does the quantum mechanical model state?
    The quantum mechanical model states that matter has properties that are associated with waves and based on the Uncertainty Principle, quantum theory emphasizes that it is impossible to determine the momentum and exact position of an electron during a particular period of time. The origin of quantum mechanics started when Max Planck and Albert Einstein discovered and proved that matter and light can both behave like particles and waves. The discovery began the quantum mechanics era, which in general is the physics of tiny things. Quantum mechanics also states that particles have a particular number that is described as quantum numbers. This number represents the properties of the particle which in general tells us how soft or hard, dull or shiny the material of the said particle is composed of.

  • What is Avagadros number?
    What is Avagadros number?
    Avagadro’s number refers to the number of units in one mole of any substance, which is defined as its molecular weight in grams; it is a key component in studying chemistry. It equals to 6.022140857 x 1023 . The units may be electrons, ions, molecules or atoms depending on the character of the reaction. The Avagadro’s number is closely related to the Avogadro’s constant, but defined differently. The Avagadro number was initially defined by Jean Baptiste Perrin as the number of atoms in one gram molecule of atomic hydrogen, meaning one gram of hydrogen.

  • How are electrons arranged in an atom?
    How are electrons arranged in an atom?
    There is the same number of electrons as protons in an atom. Inside the atom, electrons are arranged around the nucleus. The nucleus is surrounded by electron levels or shells. This is where the electrons ‘live’. Each electron shell can hold a certain amount of energy. This amount is 2 times the amount of energy an electron has squared; displayed as 2n^2 (n is the energy of the electron).   For the first 20elements, the electron shells can hold the same amount of electrons; 2 in the first electron shell, and a maximum of 8 electrons in the second and third electron shell. Electron shells closest to the nucleus have the lowest energy, and electron shells farthest from the nucleus, on the outside, have the highest energy. The arrangement of electrons in an atom determines it’s chemical properties and thus tells you what element it is. For example, fluorine has 9 electrons; 2 in the first electron shell, and 7 in the second electron shell.
