Question

Atomic no of sodium is 11 it's mass no is 23.Find the no.of protons,electrons,neutrons​

Answer 1

Answer:

So sodium has 11 protons and 11 electrons. The mass number is 23. The number of neutrons = mass number – atomic number. The number of neutrons = 23 – 11 = 12.

Answer 2

Explanation:

no. of protons =no.of electrons =11

neutrons =A-Z=23-11=12
