Answer:
s block elements:-
- The group 1 and group 2 elements are called as s block elements.
- The group 1 elements is known as alkali metals.
- The group 2 elements are called as alkaline earth metal
- They have ns1 general electronic configuration.
- They have high positive electron gain enthalpy.
- They are highly electropositive and form ionic hydrides.
- Some of them impart colour to the flame.
p block elements:-
- The elements of group 13 to 18 are called as p block elements or representative elements.
- The group 17 elements are called as halogens and group 18 elements are called as noble gases.
- They have a general electronic configuration of ns1-2 np1-6
- The group 18 elements have a completely filled electronic configuration of ns2 np6 and hence they are called as inert gases.
