Revise: Properties of Alkali MetalsBecause they are metals, we might expect them to resemble familiar metals such as iron, but two of their physical properties are unusual: they are soft and have relatively low melting points.
- Revise: Pattern in Physical Properties
A characteristic that can be observed or measured without making a new substance, such as colour, physical state or boiling point.
- Revise: Pattern in Physical Properties
A characteristic of a substance that can be observed or measured without changing it into another substance.
