WebAug 18, 2024 · Ions come in two types. Atoms that gain electrons are known as anions (AN-eye-uns). These have an overall negative charge. The size of that charge depends on how many electrons it gained. ... reduction: (in chemistry) A process in which an atom gains an electron by stealing it from another atom or molecule. Reduction is the opposite of … WebIons consisting of only a single atom are termed atomic or monatomic ions, while two or more atoms form molecular ions or polyatomic ions. In the case of physical ionization in a fluid (gas or liquid), "ion pairs" are created by spontaneous molecule collisions, where each generated pair consists of a free electron and a positive ion.
