Not Relevant
Zeff (calculate)
(Atomic #) - (# Of Shielding Electrons)
Shielding electrons
Non Valence Electrons
Electronegativity
Atoms sharing electrons
Nobles gasses electronegativity
Mostly don’t share electrons, so they don’t have a value
Ionization horizontal trend
Number of protons increase, Zeff increases, more charge on electrons, harder to take away electrons, bigger Ionization energy
Ionization energy
Energy to take an electron away
Ionization Vertical Trend
More energy levels, Electrons further from nucleus, Easier to remove
