A hydrogen ion is created when a hydrogen atom loses an electron. A positively charged hydrogen ion (or proton) can readily combine with other particles...

solutions. Acidic solutions (solutions with higher concentrations of hydrogen (H+) ions) are measured to have lower pH values than basic or alkaline solutions...

The hydrogen anion, H−, is a negative ion of hydrogen, that is, a hydrogen atom that has captured an extra electron. The hydrogen anion is an important...

needed] A simple example of a polyatomic ion is the hydroxide ion, which consists of one oxygen atom and one hydrogen atom, jointly carrying a net charge of...

atom bonded to a hydrogen atom, with one electron removed. It can also be viewed as protonated helium. It is the lightest heteronuclear ion, and is believed...

arrangement, with a hydrogen atom attached to one of the oxygens. It is isoelectronic with nitric acid HNO 3. The bicarbonate ion carries a negative one...

The dihydrogen cation or hydrogen molecular ion is a cation (positive ion) with formula H+ 2. It consists of two hydrogen nuclei (protons), each sharing...

1H+. On the other hand, calling the hydron simply hydrogen ion is not recommended because hydrogen anions also exist. The term "hydron" was defined by...

(H+) to a base—in other words, it is a base with a hydrogen ion added to it, as it loses a hydrogen ion in the reverse reaction. On the other hand, a conjugate...

as Arrhenius acid molecules in solution give up a proton (a positive hydrogen ion, H+) to the surrounding water molecules (H2O). In fact, acids must be...
