Answer a) 12 neutrons
b) 12 electrons
a) 12 protons
Explanation:
The atomic number is the number of protons in an atom and is also the number of electrons
therefore, the number of protons and electrons = 12
the mass number of an element is = # of protons + # of neutrons
if we rearrange it to find # of neutrons,
# of neutrons = mass number - # of protons
so, 24 - 12 = 12 neutrons
