how much orbitals does an electron shell have?
2 electrons with opposite spin
what is an atom determined by?
protons
whats a binary molecule?
two different elements
why must cation and anion charges must add up to equal zero?
ionic compounds are neutral which means they have no charge

what is the prefix for s6o9
nona
type 2
why does atomic radius increase down a group?
the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital.
