A metal is a lustrous, malleable, ductile, conductive element such as iron or copper. An alloy is a mixture of a metal with other elements, melted together to obtain improved properties; steel and brass are examples.
Define metals and alloys.
- Metal: an element that is usually hard, lustrous, malleable and ductile, and a good conductor of heat and electricity, for example iron, copper, aluminium, zinc and lead. Metals are crystalline solids and form positive ions.
- Alloy: a mixture of a metal with one or more other metals or non-metals, formed by melting them together and solidifying, to obtain improved properties (strength, hardness, corrosion resistance). Examples: steel (iron + carbon), brass (copper + zinc), bronze (copper + tin).
