<h2>Answer: Ion
</h2>
An ion is an atom that is electrically charged by <u>gaining or losing one or more electrons.
</u>
To understand it better:
An atom has a nucleus with electrons around it and has a neutral charge. When an electron is added or detached, this atom is electrically charged, that is, it ceases to have a neutral charge and becomes an <u>ion</u>.
In this sense, there are two types of ions:
-Anions: ions negatively charged, by the gain of electrons in the atom.
-Cations: ions positively charged, by the loss of electrons in the atom.
