Electron Configuration Quizzes Online & Trivia

The correct answer to the question “What is the electron configuration for chromium?” is letter B or 1s2 2s2 2p6 3s2 3p6 421 3d5. The actual electron configuration of Cr is [AR] 4s1 3d4 and Cu is [Ar] 4s1 3d10. Now, Letter A or 1s2 2s2 2p6 3s2 3p6 4s2 3d4 is the expected electronic configuration of a chromium since it has 24 electrons. However, because of either the orbital stability or the stability of having two full orbitals instead of having one full and another almost half full, we find the correct configuration to be letter B. This answer may be expanded with a little more research about the configuration for chromium, but this answer will serve as just a basic information for all other necessary information about chromium.

The correct answer to this question is C, 6.165x10^14 s^-1. This type of question could be found on a chemistry test, as it is related to electron configuration, which is when electrons are distributed throughout an atom. This atom can either be neutral or ionic. It also involves the distribution of molecules in orbitals. Pauli-Exclusion Principle, Hund's Rule, and Aufbau's Principle are three of the rules to solve electron configuration. Aufbau's Principle found that electrons take up the orbital in the order of energy increasements. Hund's Rule states that electrons must be emptied from an orbital before space can be occupied again. Pauli-Exclusion Principle states the electrons can have a unique set of four numbers.

How does this question even work because technically there are only 18 which is Argon but you also cant have 1 it needs to fill at least 2 or fill the shell before it.

The answer to this question is C. There aren’t a lot of people who are familiar with this element. This is a type of metal that is blue and silvery in color, especially when they are at standard temperature. If in case it would be in liquid form, its color will also change. It will become white and silvery. This type of metal will not be able to take in too much pressure. This is usually mixed with other alloys to create different items such as transistors. This can also take the form of Gallium Arsenide, which is used to generate laser light that may come from electricity.

Everyone knows that we need calcium for our bodies. It makes our body healthy and strong. When we are little, our parents used to tell us to drink all of our milk to make our bones strong. It would also help us grow. There is a lot more to calcium then what we know about it is in milk. Calcium has a gray or silver color to it, which may sound strange since it is in milk, and milk is white. However, there is more about the science of calcium. Its atomic number is 20, and it is found in period 4. Its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. It has 2, 8, 8, 2 electrons per shell.

Bromine is an elemental chemical with symbol Br and automatic number 35. It is the third lightest halogen and is fuming red-brown liquid at room temperature that evaporates readily to a colored gas. It has the properties of chlorine and iodine. It is nonmetal in group 17 of the periodic table. Bromine has the electron configuration {Ar} 3d ten 4s two 4p five, with the seven electrons in the fourth and outermost shell acting as it’s valence electrons. Like all halogens, it is one electron short of a full octet. Corresponding to periodic trends, it is intermediate in electronegativity between chlorine and iodine.

To calculate the wavelength, you will need to find the velocity of the wave and divide it by the frequency. Usually waves are measures in meters. So, the velocity is the speed of the wave. Frequency is usually measures in Hertz. This is equivalent to one second. Using the formula, you will then plug in the numbers of the frequency and wavespeed. Once you calculate this, this will be the answer. Scientific notation should be used in order to make sure the answer is accurate. Since this is a photon, you will need to use another formula which is E = RE x (1/n21 – 1/n22). RE is equal to the Rydberg constant and n1 is the final energy level of the electron and n2 is the initial energy level of the electron.

It would only be sulfur due to it's negative spin of -1/2. Aluminum would have a positive spin of +1/2

This answer is incorrect, the correct answer should be [Kr] 5s1 4d10. This is because the electrons will remove and electron from the 5s orbital and put it into the 4d orbital as completely filling the 4d orbital requires less energy
