Question

Which of the following elements has the lowest electronegativity
A) Bromine
B) Fluorine
C) Carbon
D) Lithium

Answer 1

Answer: The correct answer is option   D) Lithium

Explanation:

Electronegativity is the tendency for an atom to attract electrons.The valence shell and effective nuclear charge is also used to determine their relative electronegativity.

Lithium is the only element out of the given four elements which has more disadvantageous to gain electrons instead of losing electrons as to gain a "full outer shell"

Hope it helps!

Answer 2

Answer:

The correct answer  

D) Lithium

Explanation:

• The element with the lowest electronegativity value is francium, which has an electronegativity of 0.7.
• This value uses the Pauling scale to measure electronegativity. The Allen scale assigns the lowest electronegativity to cesium, with a value of 0.659. Francium has an electronegativity of 0.67 on that scale.
