Question

Physical chemical properties of s and p block element

Answer 1

Characteristics of s-block elements

1)They are soft metals with low melting and boiling points.

2)They have low ionisation enthalpies and are highly electropositive.

3)They lose the valence electrons readily to form +1 and +2 ions.

Characteristics of p block elements

1)P block elements include both metals and non-metals but the number of non metals is much higher than that of metals. Metallic character increases from top to bottom within a group and non metallic character increases from left to right along a period.

2)Their ionisation enthalpies are relatively higher as compared to those of s block elements.

3)They mostly form covalent compounds.
