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.
