Atomic Arrangement in Metals

A metal can exist in the gaseous, liquid or solid states depending upon the pressure and temperature. Metals have the ability to donate electrons and form a positive ion. Metals have high density, high melting temperature, good electrical and thermal conductivity, metallic lustre and crystalline structure. Structure of Solids – On the basis of structure, solids are broadly classified as: (a) Amorphous Solids. These are solids where the atoms making up the crystal are not arranged in a systematic order. Examples of amorphous solids are wood, plastic, glass, rubber etc. (b) Crystalline Solids.These…
