  1. In the nucleus of 11Na23, the number of protons, neutrons and electrons are
    1. 11, 12, 0 ​
    2. 23, 12, 11 ​
    3. 12, 11, 0
    4. 23, 11, 12
Correct Option: A

Z = 11 i.e., number of protons = 11, A = 23 ​
∴ Number of neutrons = A – Z = 12
Number of electron = 0 (No electron in nucleus) ​
Therefore 11, 12, 0.
