Hydrogen atoms have a neutral charge, containing a single proton with a positive charge and a single electron with a negative charge. Unlike all other elements, hydrogen atoms contain no neutrons. More »

In kilograms, the mass of a hydrogen atom is 1.67 times 10 to the power of negative 27 or 1.67 x 10-24 grams. That conversion is based on one atomic measurement unit of atomic mass for an atom of hydrogen. More »

The hydrogen emission spectrum is a series of colors emitted when a hydrogen atom is excited by a high voltage. These colors are created by hydrogen's electron gaining or losing energy and moving to different energy leve... More »

Ions are positively or negatively charged particles that form as a result of an atom losing an electron or gaining a proton. Ions form when metals react with nonmetals and exchange protons or electrons. In an ionized par... More »

The three particles of the atom are the proton, neutron and electron. The proton and neutron both reside in the nucleus of the atom and are positively charged and neutral, respectively. The electron is outside the nucleu... More »

The atomic radius of an atom is determined by the total number of electrons, electron shells and protons in an atom. Protons are located in the nucleus of an atom and create an effective nuclear charge. Electrons within ... More »

An electron is a negatively charged sub-atomic particle that is located in an atom along with protons and neutrons. The electrons are found in shells and sub-orbitals that surround the nucleus of the atom. More »
