DIA [1.3K]

Answer: A more electronegative atom will have more attraction to the electrons in a chemical bond.

Explanation:

An atom that is able to attract electrons or shared pair of electrons more towards itself is called an electronegative atom.

For example, fluorine is the most electronegative atom.

Due to its high electronegativity it is able to attract an electropositive atom like H towards itself. As a result, both fluorine and hydrogen will acquire stability by sharing of electrons.

Thus, we can conclude that a more electronegative atom will have more attraction to the electrons in a chemical bond.
