Document Summary

Decreases because higher effective nuclear charge pulls electrons closer to the nucleus. Aufban principle (building-up principle) --> electrons fill the lowest availible energy levels before flling higher energy levels de broglie equation --> lambda= h/mv. Heisenberg uncertainty principle --> the position and momentum of a particle can"t be measured simultaneously with precision. Heisenberg uncertainty principle equation --> x * m v (h/4 ) Hund"s principle --> electrons occupy each orbital in a subshell singly before pairing up and all electrons in singly occupied orbitals have the same spin. Ionization energy --> energy necessary to remove an electron. Ionization energy trends (same as electronegativity trends) --> increases . Decreases because electrons are further from the nucleus and harder to remove. Node --> point where (trident^2) equals zero and no electrons exist there. Order of increasing wavelength --> radio micro infared visible light uv x-rays gamma.
