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.
Species with overall positive charges are termed cations, while species with overall negative charges are called anions. Remember that ions are formed only when electrons move from one atom to another; a proton never moves from one atom to another.
3 mar 2020 · Cations are ions that have a positive charge. The word “cation” comes from the Greek word ánō, which means “up.” Examples of cations include: Silver: Ag +. Hydronium: H 3 O +. Ammonium: NH 4+. Because an electron is removed to form a cation, the cation of an atom can be smaller than the neutral atom.
21 lip 2022 · Any ion with a positive charge is referred to as a cation. Nonmetals, on the other hand, tend to gain electrons. This means the ion formed from a nonmetal atom with end up with more electrons than protons and have an overall negative charge. An anion is the general name given to any negatively charged ion. Hydrogen behaves a little differently ...
20 sie 2020 · In an atom, the total number of electrons, negative charge, equals the total number of protons, positive charge, and therefore, atoms are electrically neutral or uncharged. If an atom loses or gains electrons, it will become a positively or negatively charged particle, called an ion.
A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell.
