How m any number of proton, electron and neutron n in `.^(55)Mn^(+2)` respectively ?

A

25,27,30

B

25,25,30

C

25,23,30

D

25,27,26

Text Solution

Verified by Experts

The correct Answer is:
C
`._(25)^(55)Mn^(2+)`
No. of protons = 25 No. of electrons = 25 - 2 = 23 No. of neutrons = 25 - 25 = 30
