Cadmium has an atomic structure with 48 electrons distributed among its various energy levels or shells. These shells are numbered from 1 to 7, starting from the innermost shell closest to the nucleus. Each shell can hold a specific number of electrons: the first shell can hold a maximum of 2 electrons, the second and third shells can hold up to 8 electrons each, and so on.

Electron Configuration of Cadmium

The electron configuration of cadmium can be written as 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 4f¹⁴ 5d¹⁰ 6s² 5p². This means that cadmium has a total of 48 electrons distributed across its shells.

Determining Valence Electrons

The valence electrons of an element are found in the outermost energy level or shell. For cadmium, the outermost shell is the fifth shell, which consists of 2 electrons in the 6s orbital and 2 electrons in the 5p orbital. Hence, cadmium has a total of 4 valence electrons.

Significance of Valence Electrons in Cadmium

The presence of 4 valence electrons in cadmium contributes to its chemical properties. Valence electrons participate in bonding with other atoms, forming compounds. In the case of cadmium, it primarily forms compounds by losing or sharing its 2 outermost electrons, resulting in a +2 oxidation state.
