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.
A transition element.
Reactive
filled energy sublevels
They are most likely to lose or gain atoms. For example if u have two atoms with uneven electrons then one of the two will take the other one's to balance each other out.
An electrically charged atom or group of atoms with an unpaired electron in its outermost shell is called a free radical. If the outermost shell of an atom is half-filled with electrons, that atom is most likely to share electrons.
A filled highest occupied principal energy level
Nothing! I assume you are referring to an atom's electron shells. As a general rule, everything in nature tends to the lowest energy state. I like to think of this as the laziness principle: the lazier something can be, or the least amount of energy it can use, the best. It is the reason that a ball will roll down a hill: at the bottom, it will have less kinetic energy, therefore better. Back to atoms. An atom with its outermost electron shell filled is in the lowest energy state it can be in. Elements with their outermost shells filled (i.e. Neon, Argon, etc... look at a periodic table) are generally difficult to have react with another substance. Any reaction would require it to give up electrons: something it does not want to do. A LOT of energy is needed for a reaction to rip an electron away from one of those elements. That said, you can also use this principle to figure out why things react the way they do. ionic compounds, such as NaCl, or table salt, are formed based on both of the elements (Na and Cl) being able to fill their outermost shells. Cl normally has a charge of -1, which means it has one extra electron. Na has a charge of +1, meaning it lacks an electron. When you combine the two, Cl allows Na to borrow its extra electron, resulting in an association between the two in which they are both at a lower-level (and more favorable) energy state.

It's in the outermost shell of the electron.

Electrons called valence electrons are most likely removed. These are the outermost energy level electrons.
Chlorine is MUCH more likely to fill its outermost orbital by gaining electrons.
What is the reason that life is less likely on the outermost planets compared to the innermost planets
A filled highest occupied principal energy level
The likely word is fuel (something burned for heat or energy).Similar words are full (filled) and fool (a buffoon).
