When all atoms in a molecule have an equal attraction to the shared electrons, the molecule is called a nonpolar covalent molecule.

Here's why:

* Covalent bond: The atoms are sharing electrons, which is the defining characteristic of a covalent bond.

* Nonpolar: The equal attraction means there's no uneven distribution of electron density. This lack of a positive or negative pole makes the molecule nonpolar.

Example: A molecule of methane (CH4) is nonpolar. The carbon atom shares its electrons equally with the four hydrogen atoms.
