An acidic hydrogen atom is a hydrogen atom that has lost its electron and is running around as a hydrogen ion. The lone proton (in 1H) has loaned out its electron in a chemical reaction, like to chlorine in HCl, and when HCl is combined with water, the H and the Cl separate into H+ and Cl- ions. That H+ ion is the acidic hydrogen atom.
A hydrogen atom that has lost its one and only electron is called a hydrogen ion (H+), but more commonly, a proton. This is because the particle, lacking electrons or neutrons, is essentially just a proton.
The acidic hydrogen is the one attached to oxygen (as underlined / bold).
CH3COOH
Acidic hydrogen is a hydrogen atom from an acid which form the cation H+ by dissolution/dissociation of the acid.
Hydrogen ions
Properties of Hydrogen. Hydrogen is a nonmetal and is placed above group in the Periodic Table because it has ns1 electron configuration like the alkali metals.
Hydrogen ions give acids their acidic properties.
Hydrogen bonds between the Oxygen of one molecule and the hydrogen of another :)
Hydrogen electron configuration will be 1s1.
proton
hydrogen is an element of the periodic table and has the symbol H. hydrogen has 1 electron and is 1st on the periodic table.
Hydrogen Bonds
Hydrogen ions
It only has one electron and one proton!
Hydrogen is present in ALL acids. It is the hydrogen ions that are responsible for the acidic properties.

Hydrogen has the electron configuration of 1s1 meaning that Hydrogen has only one electron. Because of this, Hydrogen is a moderately reactive substance and behaves atypically both in intermolecular and atomic bonding. The most notable behaviour of Hydrogen is Hydrogen bonding. When hydrogen is bonded to a highly electronegative element, such as Fluorine in HF, the electron density is pulled away from the weak hydrogen atom, leaving the hydrogen almost completely deprived of electrons and a δ+ charge. This induces nearby atoms in other molecules to share their lone pair electrons with the hydrogen, effectively producing a bond similar to a covalent bond, however between molecules. Hydrogen bonding is the strongest intermolecular force and is present in compounds such as water, where the Hδ+ Effectively 'bonds' with the lone pairs of the oxygen atoms in neighbouring molecules, which is why water and ice show unusual properties.
