Calculate the number of protons, neutrons and electrons respectively in `""_(7)^(14) N^(3-)`

A

`7, 10 ,7`

B

`7, 7, 10`

C

`10, 7, 7`

D

`7, 7, 7`

Text Solution

Verified by Experts

The correct Answer is:
B
Atomic number of nitrogen = 7
Number of protons = Mass number - Number of protons = 14 - 7 = 7
Number of electrons = Atomic number + 3 `= 7 + 3 = 10`
