substance which loses electron is called?​

Answer 1

Answer:

The process in which a substance loses an electron in a chemical reaction is called oxidation. ... The atoms that lost electrons are said to be oxidized. Atoms can be oxidized by nonmetals. Reduction is gain of electrons and thus gaining of negative charge. The atom that acquired electrons is said to be reduced.

Answer 2

Answer:

Reduction is the loss of oxygen atom from a molecule or the gaining of one or more electrons. A reduction reaction is seen from the point of view of the molecule being reduced, as when one molecule gets reduced another gets oxidised. The full reaction is known as a Redox reaction. This is a good way of remembering it.

This can be remembered with the term OIL RIG when speaking about electrons.
