Answer 2

Single electron species are those that have only a single electron.

These atoms are also referred to as hydrogen-like atoms. It turns out that every one-electron atom, that is, an atom with everything but one of its electrons removed, acts like hydrogen. A hydrogenic atom is the name given to such a species. These entities are actually electrically charged ions. Electron deficient species are compounds that have less electrons than are required to achieve optimal stability.
