If a bond were to form between 2 elements, which of the pairs shown would be held together by a nonpolar covalent bond? Hydrogen and hydrogen Lithium and chlorine Aluminum and oxygen Hydrogen and chlorine

Hydrogen and hydrogen

Explanation:

A nonpolar covalent bond is formed when there is little or no electro negativity difference between the two bonding atoms in a covalent bond. This implies that the shared electron of the covalent bond is placed at an equidistant position from the nuclei of the two bonding atoms.

A bond between hydrogen and hydrogen is a homonuclear covalent bond, there is no electro negativity difference between the bonding atoms hence the covalent bond formed will be nonpolar.

Hydrogen and Hydrogen is the correct option

Explanation:

A covalent bond, is a chemical bond that involves the sharing of electron pairs between atoms so that each participating atom attain octec or duplet configuration. For many molecules, the sharing of electrons allows each atom to attain the equivalent of a full outer shell, corresponding to a stable electronic configuration.

Covalent bonding between hydrogen atoms is possible Since each hydrogen atom has one electron, they are able to fill their outermost shells or attain duplet configuration by sharing a pair of electrons through a covalent bond.
