Document Summary
Hypothetical process where we build up each atom from that which precedes in in the atomic # Write e- config for (1, z=17, minimum # of orbitals needed is 9. Look at pt for the noble gas in the period abve the atom you are looking at and add remaingn orbitals. Determine the # of e- to appear in the electron config. Neutral atoms= #of e- = # of protons= atomic # Add e- to subshells in order of increasing subshell energy. If you saw 1s2 2s1 2p1 (2s1 is not completely filled before higher energy orbitals are occupied) this is an example. Hypothetical process where we build up each atom from that which precedes in in the atomic # (2s1 is not completely filled before higher energy orbitals are occupied) this is an example. *ground state electron configurations (where lower energy orbitals are filled before higher energy orbitals.
