Calculate the number of electrons, protons and neutrons in sodium atom. Given that atomic number of sodium is 11 and mass number (atomic mass) is 23.

Text Solution

Verified by Experts

Given, Atomic number (2)=11,
Mass number (A)= 23,
Number of protons = Atomic number = 11
Number of electrons = Number of protons = 11
Number of neutrons =À-Z=23 - 11 = 12.
