Gain of electrons form anions (negative charged atoms).
ion
atoms gain and lose electrons, so they can have a full outer shell of 8 electrons (or two electrons if its the innermost shell) when atoms lose electrons it is called oxidation and when they gain electrons they are said to be reduced. OIL RIG is most commonly used to help remember that oxidation is loss and reduction is gain of electons. when atoms lose electrons they are left with a positive charge and when they can electrons they have a negative charge.
An ion.
It is called hydride, or H-.
Atoms that gain electrons are called anions, and atoms that loose electrons are called cations
Lose electrons is oxidation. To gain electrons is reduction.

The loss of an electron is called oxidation. Its opposite is reduction.The loss of an electron increases the charge by +1.
Atoms that gain electrons are called anions, and atoms that loose electrons are called cations
Ions. Cations have lost electrons and have a positive charge. Anions have gained electrons and have a negative charge.
If atoms lose electrons they will have a positively charged ion called a cation. If they gain electrons, they will have a negatively charged ion called an anion.
This is called a redox reaction, where one molecule gains electrons and one molecule loses electrons. Reduction is the gain of electrons and oxidation the gain of electrons. It can be remembered as OILRIG (Oxidation Is Loss Reduction Is Gain).
Non-metals gain electrons.
A negative ion (anion) is formed after gain of electrons in the atom.A positive ion (cation) is formed after loss of electrons from the atom.
