When an atom looses an electron is called "a cation, when gains is called an "anion".
An atom that has gained an electron becomes a negatively charged ion.
An ion
An ion.
Number of electrons are lost by an atom in a chemichl reaction
Yes. An atom that has gained one or more electrons is a negatively charged ion called an anion, and an atom that has lost one or more electrons is a positively charged ion called a cation.
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.
The atom had either lost or gained one or more electrons forming and ion. Thus the ion has an overall electric charge.
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.
A cation is an atom that has lost one or more electrons. An anion is an atom that has gained one or more electrons.
It forms a new atom.
