Metals (from Latin metallum - mine, mine) are a group of elements

Metals (from Latin metallum - mine, mine) are a group of elements

in the form of simple substances with characteristic metallic properties, such as high thermal and electrical conductivity, positive temperature coefficient of resistance, high plasticity and metallic luster.
