1. Using basic electrostatic arguments, explain why an electron “in” the 2s orbital of neon is of higher potential energy than it would be “in” the 1s orbital. 2. Explain why is it that periods 2 and 3 of the periodic table have 8 elements apiece while periods 4 and 5 have 18 elements and why aren't there 18 elements in period 3? 3. How many orbitals exists when n=5, l=3? What are these orbitals called? Are these orbitals degenerate?...

The modern periodic table is arranged the way it is because of quantum mechanics. That is, there are sections for each subshell, and the number of columns in each section are dictated by the number of electrons allowed in each subshell. Look at the number of columns that are present in each section of the periodic table: the s block has 2 columns for 2 electrons, the p block is 6 cloumns wide because the p subshell holds 6 electrons,...
