Question

Which member of each of the following pairs of atoms/ions has higher electronegativity?
a) H : Na
b) F : CI
c) C : N
d) N : P

Answer 1

Among the given pair F : Cl has higher electronegativity...

Answer 2

Hey Kapish,

◆ Electronegativity trend in modern periodic table -

- Electronegativity of elements decreases as we go down the group.

- Electronegativity of elements increases from left to right across the period.

◆ Answers -

Here, symbol of the element itself is used to indicate its electronegativity.

(a) H > Na

As Na is down in the same group as H, its electronegativity is less than H.

(b) F > Cl

As Cl is down in the same group as F, its electronegativity is less than F.

(c) N > C

As N is next to C in the same period, its electronegativity is more than C.

(d) N > P

As P is down in the same group as N, its electronegativity is less than N.

Hope this helped ..
