How many protons are there in the nucleus of a cadmium atom?

Answer 1

Cadmium has an atomic number of 48, therefore it has 48 protons in the nucleus and 48 electrons in the neutral atom.

There are a number of isotopes (list from wikipedia article Cadmium)

106Cd 58 neutrons

108Cd 60 neutrons

111Cd 63 neutrons

112Cd 64 neutrons

113Cd 65 neutrons

114Cd 66 neutrons

116Cd 68 neutrons

Answer 2

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.

Answer 3

The atomic number of cadmium (Cd) is 48. This means that Cd has 48 protons. For an electrically neutral atom, the number of protons would be equal to the number of electrons, so there would be 48 electrons. The number of neutrons can be determined by (mass number - atomic number) which is 64.

Answer 4

Every atom of the same element has the same number of protons. So whether it is an isotope or an ion of cadmium, it will have 48 protons. When cadmium becomes an ion, it loses 2 electrons to have a charge of +2. Since a neutral atom would have the same number of protons as electrons, just take the number of electrons lost from the number of protons, 48 - 2 = 46 electrons

Answer 5

Cadmium is a metal element. There are 48 electrons in a single atom.

Answer 6

The atomic number of cadmium is 48, so it has 48 electrons.

Answer 7

48 protons 48 electrons and 64 neutrons

Answer 8

48 48

Answer 9

48 protons.
