Answer 2

for I: look up Iodine's atomic number. that's how many protons iodine will have. because it's I- (negative 1 charge), number of electrons is 1 more than the # of protons

because it has a negative charge, it's an anion

second row: look up which atom has atomic # 12. it has fewer electrons than protons so it must be a positive ion (cation). the charge becomes (# of protons - # of electrons).

no idea how you're supposed to solve row 3 as there is not enough information

Answer 3

is there really not enough information isn't there any sort of way?
