Tripositive ion of an element has 13 protons and 14 neutrons . Calculate the of number of electrons present in K and M shells of the neutral atom.

A

`2 : 3`

B

`2 : 1`

C

`1 : 1`

D

`2 : 5`

Text Solution

Verified by Experts

The correct Answer is:
1
Electronic configuration of neutral atom is
`{:(K,L,M),(2,8,3):}`
therefore the ratio of the electrons present in K and M shell is `2 : 3`
