Question

The electronegativity of following elements increases in the order of?

Si, P, C, N.

Answer 1

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 :$\mathrm{Si}<\mathrm{P}<\mathrm{C}<\mathrm{N}.$
