When an atom looses an electron is called "a cation, when gains is called an "anion".
During ion formation, electrons are either gained or lost by an atom. When electrons are lost, a positively charged ion forms (cation), and when electrons are gained, a negatively charged ion forms (anion). This process balances the number of protons and electrons in the atom to achieve a stable electron configuration.
An atom that has gained an electron becomes a negatively charged ion.
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.
An ion
An atom that has gained or lost electrons is called an ion. If it gains electrons, it becomes a negatively charged ion (an anion), while if it loses electrons, it becomes positively charged (a cation).
The atom had either lost or gained one or more electrons forming and ion. Thus the ion has an overall electric 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.
It forms a new atom.
A cation is an atom that has lost one or more electrons. An anion is an atom that has gained one or more electrons.
an ion
Valance electron
Such an atom would be neutral - no electric charge.
