Atoms can be broken down into their component subatomic particles: protons, neutrons, and electrons. The atoms within an element do vary in their masses, which is why the periodic table of elements sometimes includes an average atomic mass. Protons and neutrons both have a mass of ~1 atomic ...
Hydrogen bonds are a type of dipole-dipole interaction formed between any X group-attached proton, where X is an electronegative atom, and an electronegative atom (Y) containing a pair of nonbonded electrons. The important hydrogen bonds occur in molecules where X and Y are N, O, or F ato...
The inelastic scattering of electrons for both protons and neutrons has been measured at scattering angles of fifty and sixty degrees and for incident energies between 6.5 GeV and 19.5 GeV. Elastic scattering from protons was also observed. The measurements were made at the Stanford Linear ...

Grain boundaries in oxide lattice proton conductors typically exhibit blocking effects. This may be caused by the depletion of protons in space-charge zones, the formation of lower conductivity or even insulating secondary phases, or a decrease in mobility due to disruption of the structure.59In co...

What charge would an ion that has 11 protons, 11 neutrons, and 10 electrons would have? What is the charge of an oxygen ion? What type of charge do electrons carry? What is a hydrogen bond acceptor? Where do hydrogen ions come from?
Matter, including living matter, is comprised of elements. There are 118 recognized elements, 92 of which occur in nature. Elements consist of atoms of that element. Each element is unique because each element's atoms are unique,...
Ionized hydrogen, H+, more usually denoted H II, results when neutral atoms are stripped of their electrons. It occurs at high temperatures, as in the centers of stars and in H II regions. Nuclear fusion of hydrogen ions, i.e. protons, in the stellar core generates the energy of main-...
Molecular hydrogen is composed of two protons and two electrons. The total wavefunction of a molecule consists of nuclear wavefunction and electronic wavefunction, each wavefunction being a product of orbital and spin functions. Let r1→ and r2→ are the position vectors of two electrons in the hy...
