What is the total number of protons, neutrons, and electrons in cadmium, Cd, atom that has a mass number of 112?

number of protons = 48

number of neutrons = 64

number of electrons = 48

Explanation:

The mass number of an atom is the sum of the number of protons and neutrons in the nucleus of the atom. Hence, for Cadmium;

mass number = proton number + neutron number = 112

Cadmium has an atomic number of 48. The atomic number is the number of protons found in the nucleus of the atoms of an element. Hence, the number of protons in an atom of Cadmium is 48.

proton number + neutron number = 112

proton number = 48, hence

48 + neutron number = 112

neutron number = 112 - 48 = 64

Also, for a neutral atom of an element, the number of protons and electrons must balance. This means that for a neutral atom of Cadmium with a proton number of 48, the number of electrons will also be 48.

In summary, for cadmium:

number of protons = 48

number of neutrons = 64

number of electrons = 48
