rules of quantum numbers - CORRECT ANSWERS 1. allowed values of n are 1 to infinity
2. allowed values of ℓ depend on n (n-1) equals ℓ
3. allowed values of mℓ depend on ℓ -ℓ to 0 to +ℓ
4. allowed values of ms are +1/2 or -1/2
electron described by quantum numbers - CORRECT ANSWERS
Zeff (effective nuclear charge) - CORRECT ANSWERS the positive charge of the nucleus
by the valence electrons (increases moving across the periodic table w/ increased # of protons,
makes the atom smaller because the force holds it tight)
atomic radius trend - CORRECT ANSWERS decreases from left to right
increases from top to bottom
electronegativity trend - CORRECT ANSWERS increases across a period, decreases
down a group
ionization energy trend - CORRECT ANSWERS increases up and to the right
size difference between species - CORRECT ANSWERS X->X>X+
radii of ions decrease when - CORRECT ANSWERS The effective nuclear charge is
increasing.
what happens when bromine atom becomes bromide ion? - CORRECT ANSWERS the
bromide ion is larger than the bromine atom

electrolyte - CORRECT ANSWERS A substance that dissolves in water to give a solution
that conducts electric current
why do solutions conduct electricity? - CORRECT ANSWERS the substance (or solute)
produces ions when dissolved in water, creating a electrolytic solution
strong electrolyte - CORRECT ANSWERS dissociate or ionize completely in water
weak electrolyte - CORRECT ANSWERS partially ionize in water
weak base/ acid - CORRECT ANSWERS weak electrolyte
Bases - CORRECT ANSWERS Compounds that reduce the concentration of hydrogen
ions in a solution
strong base/ acid - CORRECT ANSWERS strong electrolyte
