Two elements M and N belong to group I and II respectively and are in the same period of the periodic table. How do following properties of M and N vary ?
(a) Size of their atoms (b) Their metallic character
(c) Their valencies in forming oxides (d) Formulae of their chlorides

Text Solution

Verified by Experts

Element N is placed (group II) after element M (group I) in the same period. This means that
(a) Size of atom N is smaller than that of M. (b) Element M is more metallic than element N
(c) Valence of element M (group I) = 1
Valency of element N (group II) = 2 (d) Formulae of chlorides : `MCl" and "NCl_(2)`
