Answer:
Number of protons = 16
Number of neutrons = 16
Number of electrons = 18
Explanation:
The atom given is (32,16)S_2.
This simply Sulphur atom.
What (32,16)S_2 implies is that;
Atomic number = 16
Mass number = 32
Now atomic number means number of protons present in the atom
While mass number means number of sum of protons and neutrons present in the atom
Thus;
Number of protons = 16
Number of neutrons = 32 - 16 = 16
Now, for a neutral atom, number of protons is equal to number of electrons.
However, in this case it's not neutral but has a charge of -2.
Thus,
Number of electrons = 16 + 2 = 18 electrons
