Answer -
66-C -Mg2+ have smallest radius.
67-D-Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.
68-B-Be is the element for this data.
69- C-HF is the strongest acid
70- B
