n = 1 gives 1 orbital (1s) n = 2 gives 4 orbitals (2s, 2p) n = 3 gives 9 orbitals (3s, 3p, 3d) in general, the pattern gives n2 orbitals. More rigorously, for each n there are l values of n -1, ..., 0 and for each l value, ml = - l, - l +1, ..., l, or 2 l + 1 orbitals. Summing these for all l values gives 2.

PDF Atomic Structure: Chapter Problems - NJCTL Chemistry Atomic Structure Answers 1. In the nuclear model of the atom, protons (and neutrons) are housed in a small, dense nucleus. Electrons surround the nucleus in an area of mostly empty space. 2. If electrons are electrically attracted to nucleus and would, therefore, have centripetal acceleration in order to orbit the nucleus.
