The atomic number of cadmium (Cd) is 48. The atomic weight of Cd is 112.41 grams per mole.

See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this element.
Cadmium has a stable atomic mass number of 112 (48 protons, 64 neutrons). It has several stable isotopes: Cd 110, Cd 111, Cd 112.

To find the number of neutrons in one atom, subtract the atomic number from the atomic mass. (Atomic mass is about equal to the number of nucleons.) For Cadmium: 112.411-48=64.411, so about 64 neutrons. However, there are several isotopes of Cadmium, so there are several answers to this question. Cadmium 110, Cadmium 111, and Cadmium 112 are all stable, and they have 62, 63, and 64 neutrons, respectively. Cadmium 113 and Cadmium 116 are both radioactive, and they have 65 and 68 neutrons.
