What substance has nonpolar covalent bonds?

Answer 1

Diamond, dihydrogen, carbon?

Any #"element-element"# bond is necessarily non-polar and covalent. I could choose molecular species, i.e. homonuclear diatomic molecules, i.e. #H_2# or #X_2# or #O_2# or #N_2#; or I could choose non-molecular species, for instance graphite or diamond.

Substances with nonpolar covalent bonds include elements such as hydrogen gas (H2), oxygen gas (O2), nitrogen gas (N2), and noble gases like helium (He), neon (Ne), and argon (Ar). Additionally, molecules composed of identical atoms, such as diatomic molecules, typically have nonpolar covalent bonds. Examples include hydrogen gas (H2), oxygen gas (O2), and nitrogen gas (N2).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
