Metallic Solids (The Solid State - 6) || Chemistry for Class 12 in Hindi

Описание: In this Chemistry video in Hindi for class 12 we explained what metallic solids are and what their properties are. These solids are made up of metal atoms. These atoms lose electrons in crystal lattice and become positive ions.

This is a topic from the chapter 'The Solid States' for Class 12th Chemistry.

Metals are orderly collection of positive ions surrounded by and held together by a sea of free electrons. These electrons are mobile and are evenly spread out throughout the crystal. Each metal atom contributes one or more electrons towards this sea of mobile electrons. These free and mobile electrons are responsible for high electrical and thermal conductivity of metals. When an electric field is applied, these electrons flow through the network of positive ions. Similarly, when heat is supplied to one portion of a metal, the thermal energy is uniformly spread throughout by free electrons. Another important characteristic of metals is their lustre and colour in certain cases. This is also due to the presence of free electrons in them. Metals are highly malleable and ductile.
