Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions migrate under the influence of an electrical field and are the conductors of electric current in electrolytic cells.

An ion (/ ˈaɪ.ɒn, - ən /) [1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention.
20 lis 2021 · In chemistry, the definition of an ion is an electrically charged atom or molecule. This means the atom or molecule has an unequal number of protons and electrons. Neutrons carry no net electrical charge, so they don’t affect ions directly.
2 sie 2021 · Under this broader definition, an atom can be an ion, but not all ions are atoms. The difference between an atom and an ion has to do with net electrical charge. Examples of atoms include hydrogen (H), helium (He), iron (Fe), and any other element on the periodic table.
4 wrz 2019 · An ion is defined as an atom or molecule that has gained or lost one or more of its valence electrons, giving it a net positive or negative electrical charge. In other words, there is an imbalance in the number of protons (positively charged particles) and electrons (negatively charged particles) in a chemical species.
Ion Definition. An ion is an atom or molecule with either a positive or negative electrical charge. An ion has a charge because the number of protons does not equal the number of electrons; to find the number of protons and electrons, check out this article.
3 lip 2019 · What Is an Ion? Ions are atoms with extra electrons or missing electrons. When an atom's outermost orbital gains or loses electrons (also known as valence electrons), the atom forms an ion. An ion with more protons than electrons carries a net positive charge and is called a cation.
