The group 1 elements Li, Na, K, Rb, Cs, and Fr are alkali metals. When sliced, the alkali metals are all supple, metallic, and lustrous. They are good electrical conductors, have low melting temperatures and densities, and react readily with water. Each of them has a valence electron that they can readily lose to produce ions
