The no. Of protons and neutrons in it are 11 ad 12 respectively.
Explanation:
Atomic number is defined as the number of protons or number of electrons that are present in an atom.
For an electrically neutral atom,
Atomic number = Number of electrons = Number of protons = 11
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
23= 11 + Number of neutrons
Number of neutrons = 12
