Best Answer

When an atom gains or loses electrons, it is trying establish a more stable situation in which it has a full valence shell. An atom that has gained or lost valence electrons is called an ion. When a positive ion and a negative ion can bond due to their opposite charges. This is called an ionic bond.

Ions. Cations are positive ions (lost electrons) and anions are negative ions (gained electrons).

Those would be ions. They are atoms that carry a charge.

An atom that has gained or lost electrons is called an ion. An atom that has gained one or more electrons becomes a negatively charged ion called an anion. An atom that has lost one or more electrons becomes a positively charged ion called a cation.


What are Atoms that carry an electrical charge called because they have gained or lost electrons?

Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.


The loss of electrons by a molecule atom or ion is called?

oxidation. Gaining electrons is called reduction.


What is an oxidation number in chemistry?

The oxidation number of an ionic atom or molecule is the number electrons that it has lost or gained.


What forms when an atom has lost or gained electrons?

When an atom looses an electron is called "a cation, when gains is called an "anion".


What is an atom that has an electric charge because it lost or gained electrons?

An atom that carries an electrical charge because it has gained or lost electrons is called an "ion". An atom that has gained one or more electrons, and has a negative electrical charge, is called an "anion". An atom that has lost one or more electrons, and has a positive electrical charge, is called a "cation". The term "ion" is used to refer to both cations and anions collectively or non-specifically.


What are the charged particles that form when atom gain or loose electrons?

A charged atom - one that has either lost or gained electrons - is called an ion.
