Question

electronegativity is defined as the power of an atom in a molecule to
a) Repel electrons towards itself
b) Attract electrons towards itself
c) Expand itself
d). All of the mentioned​

Answer 1

Answer:

b) attract elections towards itself.

Answer 2

b) Attract electrons towards itself

Explanation:

• Electronegativity is defined as the power of an atom in a molecule to attract electrons towards itself.

Hence, option b is correct.

• Electronegativity is actually the measure of the tendency of an atom to attract a bonding pair of electrons.

• An atom's electronegativity is affected by its atomic number and the distance at which its valence electrons  from the charged nucleus.

• The power of an atom in a molecule to repel electrons towards itself and /or expand itself is not called electronegativity.

Hence, option a and c are incorrect.
