Because it is a proton. A hydrogen atom is a proton and an electron; if you take the electron away to form a positive ion, all that's left is the proton.
A hydrogen ion or a proton
H+ or a proton.
A hydrogen ion is often referred to as a proton. It is a positively charged particle with the symbol H+ that is commonly found in acidic solutions.
In aqueous solutions, when hydrogen ion (H+) is released, it immediately forms a hydronium ion (H3O+). However, for simplicity, H+ is often referred to as a proton because the lone hydrogen ion lacks an electron and behaves like a free proton. This simplification is commonly used in chemistry and biochemistry discussions.
Dihydrogen monoxide
H+ can be either called a hydrogen ion or a proton.
A positive ion that releases a proton to water.
Acids are able to donate, split off, ionise into proton(s) and an anion.Example:Acetic acid --> proton and acetateCH3COOH --> H+ + CH3COO-
H-1. Hydrogen has only one proton and electron; if this electron is removed a hydrogen ion is formed - effectively a proton.
Well, it depends on what ion you are talking about: the H+ ion, 'proton,' or the H- hydride ion. Anions, Lewis bases accept the proton or H+ ion (HCl); but active metals can react with H- to form metal hydrides (NaH for example)
Hydrogen (H) is not the same as the Hydrogen ion H+. H+ is the term for a hydrogen atom that has lost its electron. Since the number of electrons is not equal to the number of protons, it is called an ion. Since the hydrogen atom is comprised of one proton and one electron, the hydrogen ion H+ is simply a proton.
The hydronium ion is simply the water ion with an extra proton. (H+) So: H2O + H+ ---> H3O+
