The electronegativity of the following elements increases in the order (a) C < N < Si < P (b) N < Si < C < P (c) Si < P < C < N (d) P < Si < N < C |
|
Answer» Correct option is (c) Si < P < C < N On moving across a period from left to right in periodic table electronegativity increases. This is because across the period the size of an atom decreases. While on moving down the group, electronegativity decreases. Thus, the correct order of electronegativity is Si < P < C < N (1.8) (2.1) (2.5) (3.0) |
