Document Summary

1 kind of s orbital->2 electrons max in s orbital. 3 kinds of p orbitals->6 electrons in the p orbital. 5 kinds of d orbitals->10 electrons max in the d orbital. 7 kinds of f orbitals->14 electrons max in the f orbital. System tends to go lower pe (more -) Magnitude increases w/ increased charge or +2 rather than +1. In multiclectron atoms, any one elctron experieneces + charge from the nucleus (attractive) and - charge from other electrons (repulsive) Repulsion is a shielding from full effects of nucleus charge. 1s^2 is the inner elcectron (1 means closer to nucleus) Inner core electrons shield the outer electrons from the nucelus. Li has 3 protons in nucleus (ballances out 3 electrons) so nucleus is left with 3+ charge. Charge of electron -inner electron=charge felt by outer e- In the hydrogen atom, all sub sells of a principal shell (n) are all the same energy level level.
