explain

Alkali metals are highly conductive, highly reactive, soft, and lustrous. These elements typically have one valence electron, making them very reactive and easily able to form positive ions. They are also very good conductors of heat and electricity. Their softness and lustrous appearance are due to their low melting points and ability to form a thin layer of oxide on their surface, which gives them a shiny appearance. Therefore, an element that exhibits these characteristics is most likely to belong to the alkali metals group.
