That, or they, would be the outer most shell electrons. The one(s) that get shared when elements bond. The one that moves out and up when struck by a photon. The one that makes light when it falls back down (gives up its' energy) to its' original shell.
ADD: It is a valence electron.

Electrons in the outermost principal energy level are called valence electrons.
valence electrons are the electrons in the outermost energy level
The outermost principle energy level for strontium is the 5th energy level.
Helium only needs 2 valence electrons to have a filled outermost energy level.
Valence electrons are the electrons in the outermost energy level.
Electrons in the outermost principal energy level are called valence electrons.
The chloride ion (Cl-) has 8 electrons on the outermost energy level.

Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Halogens have six valence electrons in the outermost energy level.

The total number of electrons in Phosphorus (P) is 15 (its atomic number). The first energy level contains 2, the second energy level contains 8, and the third energy level contains 5.
Outermost energy level is full if there are 8 electrons in the valence shell.
4th energy level.
An atom with an incompletely filled outermost energy level is likely to be reactive. This is because it wants to acquire a filled outermost energy level.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
The outermost principle energy level for strontium is the 5th energy level.
