An atom with 3 protons and neutrons will have a valency of

A

3

B

7

C

1

D

4

Text Solution

Verified by Experts

The correct Answer is:
C
Given that, number of protons in an atom = 3 and number of neutrons = 4
Electronic configuration of `""_(3)Li = overset(K)2, overset(L)1`
As, it has one valence electrons, therefore its valency is also 1.
