Document Summary

Four quantum numbers of an electron are its id# n related to size of orbital n=1,2,3infinity. Three quantum numbers n- en = - rh z2/n2 for one e species l- angular momentum related to shape l=0,1,2,(n- 1) when l=0 (s), l=1(p), l=2 (d) l=0 s orbitals. Nodes- regions of space where electron value is = to 0 l=1 p orbitals l=2 d orbitals. Total values (n) ml - magnetic quantum # related to the orientation. Shell is the group of its orbitals that have the same value of n n=0,1,2,3, Subshell is a group of orbitals with same number/values of n and l. orbitals that have same value of n uey differ in l belong to diff. subshells. There are infinity # of subshells in a shell. n=1 first shell s n=2 second shell s,p. Every subshell has 2l+1 orbitals s p d f. In a shell there are: subshells (n) shells (n2) max.
