Here is a chart of element charges and an explanation of how to find the charge of an element if you don’t know it. The difference between charge, oxidation state, and valence is explained, too. You can download and print these graphics and tables for references.
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 of positive electric charge, called a proton.
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 and therefore is only seen isolated when it is in a gaseous state or a nearly particle-free space. [1]
For example, hydrogen sometimes has a charge of zero or (less commonly) -1. Additionally, although noble gas atoms almost always carry a charge of zero, these elements do form compounds, which means they can gain or lose electrons and carry a charge.
The hydrogen atom consists of a single negatively charged electron that moves about a positively charged proton (Figure \(\PageIndex{1}\)). In Bohr’s model, the electron is pulled around the proton in a perfectly circular orbit by an attractive Coulomb force.
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral hydrogen atom contains a nucleus of a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe. [1]
Bohr’s model of the hydrogen atom, proposed by Niels Bohr in 1913, was the first quantum model that correctly explained the hydrogen emission spectrum. Bohr’s model combines the classical mechanics of planetary motion with the quantum concept of photons.
A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons.
The hydrogen atom consists of a single negatively charged electron that moves about a positively charged proton . In Bohr’s model, the electron is pulled around the proton in a perfectly circular orbit by an attractive Coulomb force.
The letter \(e\) indicates the elementary charge; it is the charge on the proton, and the absolute value of the charge on the electron. It’s value is 1.602 × 10 − 19 C, where C is “Coulombs”, the SI unit of charge. Finally, \(r\) indicates the distance between the electron and the proton.
