Define Isoelectric
Same number of electrons
Define nuclear charge
Attractive force between the protons in the nucleus and the electrons in the energy levels.
More protons = (greater/smaller) nuclear charge
greater
Define shielding
When inner (core) electrons shield outer electrons (valence) from the attractive forces of the nucleus.
Less shielding, electrons pulled (towards/away) nucleus, (more/less) stable, (more/less) energy.
towards, more, less
An orbital that penetrates into the region occupied by core electrons is ____ shielded from nuclear charge and therefore has ______ energy.
less, lower
When drawing arrows for dipoles, arrow points towards molecule that is more . . .
electronegative.
Formal Charge =
Valence e- - lone e- - (shared e-/2)
When doing hybridization, use the ____ geometry.
electron-pair geometry
Lattice Energy =
q1 * q2 / r2
where q is charge of ion
r is distance between them
Lattice energy __________ upon ___________ size of ions.
decreases, increasing
