Final answer:

When a hydrogen atom gains one electron, it becomes a negatively charged anion. Atoms are electrically neutral until they gain or lose electrons, resulting in the formation of ions.


Explanation:

When a hydrogen atom gains one electron, it becomes negatively charged and is called an anion. This results in the atom having more electrons than protons, causing a net negative charge.

Atoms are electrically neutral when the number of protons equals the number of electrons. However, when an atom gains or loses electrons, its charge changes, and it becomes an ion.

For example, a neutral sodium atom losing one electron becomes a positively charged cation, while a neutral chlorine atom gaining one electron becomes a negatively charged anion.
