Assume that you have a new "triad" of elements (a, b and c. with similar properties. a is the smallest element and has a mass of 30 u. c is the largest element and has a mass of 90 u. the mass of b would be approximately u.

Complete the table for ion charge based upon their losing or gaining electrons in the outer shell. (use the periodic table as necessary.) group most likely ionic charge # of valence electrons i +1 ii +2 iii +3 iv +4 or -4 v -3 vi -2 vii -1 viii 0
