Question

Four quantum numbers of the outermost electron are : 5 , 0 , 0+ 1/2 . The element belongs to
A p-block
B f-block
C s-block
D d -block​

Answer 1

Answer:

C. s-block

Explanation:

We have,

n=5

l=0,

m=0 and

s=+1/2

This indicates that the Valence electron is present in 5S subshell.

We know, elements with outer electronic configuration ns^1-2 comes under s-block. Hence the given element is in s-block.
