An atom is determined to contain 12 protons, 10 electrons, and 12 neutrons. What are the mass number and charge of this atom or
shepuryov [24]
Mass number= atomic number + number of  neutrons.
A=Z+N
Z=number of protons=12
N=12

A=12+12=24

If, we have 12 protons and 10 electrons, the charge of this ion is +2

Therefore: mass number:24; charge: +2

Answer: a. mass number: 24; charge: +2
