1.	The atomic number of Na and Mg is 11 and 12 respectively and they belong to the same period.a) Which one would have smaller atomic size.b) Which one would be more electro positive.c) To which group would each one belong
Answer» a) Mg has smaller atomic size due to high nuclear charge (Na → 2, 8, 1; Mg → 2, 8, 2) b) Na would be more electro positive because it can lose the valance electron more easily. c) Na belongs to group 1 and Mg belong to group 2 as Na contains 1 and Mg contains 2 valence electron.
