Answer:

the mass is 24

Step-by-step explanation:

The atomic number is defined as the totall number of electons in the atom in its non bonded state.

Thus the number of electron is 1w, atomic number is also 12.

Mass number is defined as the number of protons + neutrons in the nucleus of an atom.
