The list below gives the elements arranged by increasing atomic number and shows the number of electrons per shell. I am fairly sure that orbitals and shells are the same thing. However, the outcome is the following: Each energy level (shell) has more subshells available to it: The pattern is thus: $2, 8, 18, 32, 50, 72, $ or $2n^2$. When molecular orbitals form, two valence electrons are required to be situated in between two atoms for a molecular orbital, forming a chemical bond. Similarly, an elements column number gives information about its number of valence electrons and reactivity. 3(1964),6-28.
