A charged particle formed when an atom, or group of atoms, loses or gains electrons.

An atom or group of atoms with an overall electrical charge because it has gained or lost electrons.

An ion forms when electrons are gained or lost; its nucleus is unchanged.

An atom or group of atoms with an overall electric charge because electrons have been lost or gained.

An electrically charged particle formed when an atom, or group of atoms, loses or gains electrons.

An atom or group of atoms with an overall electrical charge because electrons have been lost or gained.

A charged particle formed when an atom loses or gains electrons.

A charged particle formed when an atom or group of atoms gains or loses electrons.

An atom or group of atoms with an overall electrical charge because electrons have been gained or lost.

An atom or group of atoms carrying an overall positive or negative electrical charge.

An ion is an atom or group of atoms with an overall electrical charge. Its charge is written at the upper right. Na⁺ is one sodium atom with a 1+ charge, whereas O²⁻ is one oxygen atom with a 2− charge.

A charged atom or group of atoms formed by gaining or losing electrons.

An atom or group of atoms with an overall positive or negative charge because it has lost or gained electrons.

An atom or group of atoms with an overall positive or negative charge.

An atom or group of atoms with an overall positive or negative electrical charge because it has lost or gained electrons.

A charged particle formed when an atom, or a group of atoms, gains or loses electrons.

A positively or negatively charged particle formed when an atom or group of atoms loses or gains electrons.

An atom or group of atoms with an electrical charge.

An atom or group of atoms carrying an overall electrical charge.

A charged particle formed when an atom, or a group of bonded atoms, gains or loses electrons.

An atom or group of atoms with an overall electrical charge; a positive ion has lost one or more electrons.

A charged particle formed when an atom, or a group of atoms, gains or loses electrons.

Its nucleus does not change, so ion formation leaves its atomic number, mass number, number of protons and number of neutrons unchanged.

A charged particle formed when an atom, or a group of atoms, loses or gains electrons.

An atom or group of atoms with an overall electrical charge because electrons have been lost or gained.

An atom or group of atoms with an overall electrical charge because it has gained or lost electrons.

A positively or negatively charged particle formed when an atom, or group of atoms, loses or gains electrons.

An atom or group of atoms with an electrical charge because electrons have been lost or gained.

A charged particle formed when an atom, or a bonded group of atoms, gains or loses electrons.

An atom or group of atoms with an electrical charge.

An electrically charged particle formed when an atom or group of atoms gains or loses electrons.

An atom or group of atoms with an electrical charge, formed when electrons are lost or gained.

A charged particle formed when an atom, or a group of atoms, loses or gains electrons.

Losing electrons produces a positive ion; gaining electrons produces a negative ion. The number of electrons lost or gained determines the ion's charge.

An atom or group of atoms with an overall electrical charge because it has gained or lost electrons.

A charged particle formed when an atom, or a group of atoms, gains or loses electrons.

A charged particle formed when an atom, or group of atoms, gains or loses electrons.

An atom or group of atoms with an overall electrical charge because it has lost or gained electrons.

An atom or group of atoms with an overall electric charge because it has gained or lost electrons.

A charged atom or group of atoms.

An electrically charged particle formed when an atom, or a bonded group of atoms, loses or gains electrons.

An electrically charged particle; plants take up dissolved nutrient ions through their roots.

A positive or negative ion, such as a metal ion or a sulfate ion.

An ion’s charge changes the number of electrons, not the numbers of protons or neutrons. A positive ion has fewer electrons than protons; a negative ion has more.

Use the ion formed, not appearance alone, for the defining distinction: a metal forms positive ions; a non-metal does not.

Do not say that every non-metal forms negative ions. Non-metal atoms may gain electrons, share electrons, or—like the noble gases—hardly react.
