Where would electrons in the d sublevel be found? Only in the n = 3 energy level in energy levels 3 possibly in any energy level

Answer;

only in the n = 3 energy level

Explanation; The atom of a chemical element is made up of sub-atomic particles which are the neutrons, protons and electrons. The neutrons and protons occupies the nucleus of an atom while the electrons occupy the energy levels. The first energy level (n=1) of an atom occupies a maximum of two electrons because it has only an S-orbital which can only have two electrons. The second energy level (n=2) can have a maximum number of 8 electrons, since it contains, one S - orbital which can hold two electrons, and a p-orbital which can accommodate six electrons. The third energy level (n=3) can have a maximum number of 18 electrons, because it has the S-orbitals which holds 2 electrons, the p-orbital which holds 6 electrons and the d-orbital which holds 10 electrons.
