Lesson details
Key learning points
- Many non-metals are in the gas state at room temperature.
- Some non-metals form diatomic molecules that contain two atoms (e.g. O₂, N₂, H₂, Cl₂).
- Some non-metals are monatomic and do not form molecules.
- Noble gases are monatomic and are listed in the right-hand column of the periodic table.
Keywords
Molecule - Molecules are made up of two or more atoms chemically bonded together. These are usually non-metals.
Monatomic - A monatomic element consists of only single atoms.
Diatomic - A diatomic element consists of two of the same type of atom chemically bonded together.
Common misconception
Assuming that substances like sodium chloride (NaCl) are diatomic.
It is very important to emphasise that only non-metals exist as monatomic or molecules.
