Hi viewers:
Here we will discuss about the very basic ideas about Electrovalency and Covalency.

Electrovalency

The valency of the elements which enable them to combine with one another through direct transfer of electrons and to form ions in order to get  the electronic configuration of inert gases and are held together by electrostatic force of attraction is known as electrovalency or ionic valency

 

Electrovalent compound

  1. It is formed by transfer of electron
  2. It is an electrolyte
  3. It ionizes in aqueous solution or molten state
  4. Melting points and boiling points are very high
  5. If it dissolves, it dissolves in water

 

 

Covalency

The valency of the elements which enable them to combine with one another through mutual sharing of electron pairs in order to attain the electronic structure of inert gases, to form a molecule is known as covalent bond

 

Covalent compound

  1. It is formed by mutual sharing of electrons
  2. It is non-electrolyte
  3. It does not ionizes in aqueous solution
  4. Melting points and boiling points are very low
  5. It dissolves in organic solvent
