(a) How does the atomic radius change as you go (i) from left to right in a period? (ii) down a group in the periodic table?
(b) Two elements X and Y have atomic numbers 12 and 16 respectively. Write the electronic configuration for these elements. To which period of the Modern Periodic Table do these two elements belong? What type of bond will be formed between them and why?

Text Solution

(a) (i) Atomic radius decreases. (ii) Atomic radius increases.

They will form ionic bond because X is a metal and Y is a non-metal. X loses two electrons which will be gained by Y.
