Question

Which of the following is not true as we move down a group of s and p-block elements in the periodic table

a. Effective nuclear charge is relatively constant
b. Atomic radius increase steadly
c. The value of principal quantum number increases
d. Electronegativity also increases

Answer 1

D. because as u move down the periodic table, the atomic radius increases there decreasing the electronegativity.

Answer 2

MrSensitiveis right. d is not true. Electronegativity decreases as you go down a group.

Answer 3

thanks @Preetha

Answer 4

The tendency of an atom to attract shared electron pair of bond towards itself is known as

Electronegativity
Electron affinity
Ionization energy
Hydrogen bonding
