The number of electrons in the first two levels of an atom of sodium is as follows:Level 1 contains a single s sublevel = 2 electronsLevel 2 contains s and p sublevels = 2 + 6 = 8 electrons. So far, levels 1 and 2 have given us 10 electrons.
Element x has the highest first electron affinity in its period, the ground state electron configuration of its common is: [Kr] 5s2 4d10 5p6 Element Y is the second largest element in its period; its valence electron are in orbital(s) that have n= 6.
