Solution

Electronegativity :

  • It is defined as the ability of an atom to attract the shared electrons of a covalent bond to itself.
  • If atoms bonded together have the same electronegativity, the shared electrons will be equally shared.
  • Electronegativity of an atom is affected by the distance of its valence electrons from the charged nucleus.

Order of elements :

  • The electronegativity decreases from top to bottom in the periodic table and increases across a period from left to right.
  • So the order of elements is :Si<P<C<N.
