In the nucleus of `._(11)Na^(23)`, the number of protons, neutrons and electrons are

Options

A. 23,11,12
B. 23,12,11
C. 12,11,0
D. 11,12,0

Answer

D

Explanation

In the nucleus of `""_11Na^23`, there are no electrons.
`therefore` no. of electrons = 0 , no. of protons = atomic no. = 11 and number of neutrons = A-Z=23-11=12
The correct choice is 11, 12, 0
note: - The atom `""_Na^23` will contain 11 electrons , 11 protons and 12 neutrons.
