Question

Write three necessary conditions for the formation of a covalent bond


Open in App
Solution

Covalent bond:

  • A covalent bond is a chemical bond formed by the mutual sharing of electrons between atoms.
  • The electrons are attracted by the atoms simultaneously.
  • When the electronegativity difference between the two atoms is small then only covalent bond forms.

Condition:

  • The electronegativity difference between the atoms that form a covalent bond must be equal.
  • To establish a covalent bond, the forces of attraction between the atoms should be equivalent.
  • Both atoms' ionisation energies must be high in order for electrons to be difficult to remove.
  • When an atom loses or contributes one electron to form an electron pair, a covalent bond is formed.
  • Each of the two participating atoms must have 5,6&7 electrons in their valence shells, or outermost shells, to form a covalent bond.
