Characters of S-block elements :-

S-block elements [ difination ] :-

The elements in which the differtiating electrons enters into ns-subshell are called S-block elements .

1) Their general electronic configuration is ns^1-2

2) S-block elements are arranged in 2 groups . They are group 1 ( I A ) , group 2 ( II A ) .

3) First group ( IA ) elements are called Alkaline metals .

4) Second group ( IIA ) elements are called Alkaline earth metals .

5) Reactivity of the metals decreases in groups and increases in periods .

• The alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

• The s-block elements include hydrogen (H), helium (He), lithium (Li), beryllium (Be), sodium (Na), magnesium (Mg), potassium (K), calcium (Ca), rubidium (Rb), strontium (Sr), cesium (Cs), barium (Ba), francium (Fr) and radium (Ra).
