Question

Tendency of an atom to attract electrons to itself when combined in a group is called:

• A. Workfunction
• B. Electronegativity
• C. Polarization
• D. Catenation

Hint:

Electronegativity increases with the increase in effective nuclear charge and decreases with the increasing atomic size. The atoms that have high electronegativity include fluorine and oxygen, while those with low electronegativity are cesium and francium.

Answer 1

The Correct Option is B

Electronegativity is the measure of an atom’s ability to attract shared electrons in a chemical bond. Factors influencing electronegativity include:
• Atomic size: Smaller atoms have higher electronegativity as the nucleus is closer to the bonding electrons.
• Nuclear charge: Higher positive charge in the nucleus increases the attraction for bonding electrons.
For example, fluorine is the most electronegative element due to its small size and high nuclear charge.
