When there is unequal sharing between two atoms of the electrons in a bond, which type of bond is it? polar covalent ionic nonpolar covalent electronegative

The correct answer is polar covalent.

In a covalent bond when two atoms have a difference in electronegativity, then the shared electron is drawn closer towards the atom that has higher electronegativity. For example in HCl, the Cl atom is more electronegative than the H atom. So the shared pair of electron in the H-Cl bond is drawn closer towards the Cl atom causing it have a partial negative charge and the H atom has a partial positive charge.

H-Cl

the answer is a and have a great day

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
