Question

Arrange the following elements in the increasing order of electronegativity.

• A. Carbon (C)
• B. Silicon (Si)
• C. Germanium (Ge)
• D. Tin (Sn)

Answer 1

All the given elements belong to group 14. Down the group, electronegativity decreases because atomic size increases and effective nuclear charge decreases.
So the correct order of electronegativity is Sn < Ge < Si < C.
