Why is H+ commonly known as a proton?

Hydrogen ion, strictly, the nucleus of a hydrogen atom separated from its accompanying electron. The hydrogen nucleus is made up of a particle carrying a unit positive electric charge, called a proton (q.v.). The isolated hydrogen ion, represented by the symbol H+, is therefore customarily used to represent a proton.

Besides, can hydrogen be a cation?

A hydrogen atom is made up of a nucleus with charge +1, and a single electron. Therefore, the only positively charged ion possible has charge +1. Hydron: general name referring to the positive ion of any hydrogen isotope (H+) Proton: 1H+ (i.e. the cation of protium)

Can hydrogen be positive or negative?

One Hydrogen ( ) has a positive charge +1. This has nothing to do with it having more protons than electrons, as it has one of each. Think of it as 'willing' to donate one electron, or it has +1 electrons see, it is on the plus side. One Oxygen ( ) has a negative charge of -2.
