How many electrons, protons, and neutron...

How many electrons, protons, and neutrons are there in an atom of atomic number 11 and mass number 24?

Text Solution

Verified by Experts

The number of electrons in nucleus =0, electrons do not exist in the nucleus
Here Z=11 , A=24
Number of protons in nucleus (Z) =11
Number of neutrons in nucleus (N)=A-Z=24-11=13
