Meaning
Cadmium is a transition metal element, on the Periodic Table, with an atomic number of 48.
About Cadmium
Molecular Structure
- Cadmium has the chemical symbol Cd.
- Cadmium atoms join together in large numbers to form a giant metal molecule.
Atomic Structure
- Cadmium as 48 protons and 64 neutrons in its nucleus giving it an Atomic Number of 48 and an atomic mass of 112.
- Cadmium is in Period 5 of the Periodic Table because it has 5 electron shells.
Properties

Key Stage 4
Meaning
Cadmium is a transition metal element, on the Periodic Table, with 48 protons in the nucleus.
About Cadmium
Molecular Structure
- Cadmium has the chemical formula Cd.
- Cadmium atoms join together in a giant metallic structure.
Atomic Structure
- The most stable isotope of Cadmium has 64 neutrons in its nucleus giving it an atomic mass of 112.
- Cadmium is in Period 5 of the Periodic Table because it has 5 electron shells.
- Cadmium loses electrons to form positive metal ions.
Properties
- Cadmium forms ionic bonds with non-metals.
- Cadmium is a metal element so it is a good thermal conductor and a good electrical conductor.
