Question

Give the electronic configuration of 'S' block elements by SPDF method.​

Answer 1

Answer:s block elements have an outer shell of just 1 or 2 s electrons i.e. s1 or s2 configuration beyond an inner noble gas configuration (2 per period from period 2 onwards), that is groups 1 and 2. Technically, hydrogen and helium are in the s block, but bare little chemical similarity with the group 1 and group 2 metals.
