Question

Among the elements given below, the elements with the least electronegativity is:

• A. Lithium
• B. Carbon
• C. Boron
• D. Fluorine

Answer 1

The correct option is A

Lithium

An explanation for the correct option:

(A) Lithium

• The electronegativity of an atom is the tendency to attract shared electrons when forming a bond.
• It increases across a period from left to right.
• Lithium belongs to group I and II period in the periodic table.

The explanation for the incorrect option:

(B) Carbon is placed in group 14 and II period.

(C) Boron is placed in group 13 and II period.

(D) Fluorine belongs to group 17 and II period and is the most electronegative element.

Hence, The element with the least electronegativity is Lithium.

Therefore, option (A) is correct.
