Which of the following elements would be expected to have the highest electronegativity? 1. As
2. Li
3. P
4. Al
5. Ge

option (3) P is the correct answer.

Explanation:

electronegativity of As is 2.0

electronegativity of Li is 1.0

Electronegativity of P is 2.1

Electronegativity of Al is 1.5

electronegativity of Ge is 1.6

So P (phosphorus) would be expected to have highest electronegativity.

Electronegativity measures the Capability of an atom to pull the shared paired of electrons.

Electronegativity is determined by the following factors

nuclear charge.

the number and the location of different electrons inside the atomic shells.
