Classification of Elements and Periodicity in Properties

Arrange the following elements in increasing order of electronegativity: N, O, F, C, Si.

Choose the correct answer from the options given below:

  1. A.Si < C < O < N < F
  2. B.O < F < N < C < Si
  3. C.F < O < N < C < Si
  4. D.Si < C < N < O < F✓

Solution

Electronegativity rises across a period and falls down a group: Si < C < N < O < F.
