The noble gases (helium, neon, krypton, xenon, radon) have complete outer electron shells, and the halogens (fluorine, chlorine, bromine, iodine, astatine) have almost complete outer electron shells. Note that the chemical properties of an element with a complete outer shell are tremendously different from the chemical properties of an element with an almost complete outer shell.
The answer is Reactive
transition metals
Outermost have more energy than innermost. As electrons move inward, they release energy.
Yes, but only partially. Part of the energy converted to heat is lost, forevermore.Yes, but only partially. Part of the energy converted to heat is lost, forevermore.Yes, but only partially.

3s^2
The amount of energy needed to remove the outermost electron.
Because their outermost energy level is only partially filled, some elements are highly reactive, I believe.
reactive
Because all the atoms of these elements in Family 18 have filled outermost energy levels.
The noble gas elements have outermost energy levels with full s and p orbitals.
name the group of elements that have only one electron in their outermost energy level
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
the outermost energy level! ( :
Transition elements can form bonds by losing electrons from both the outermost and next to the outermost principal energy levels.
The names of elements characterized by the belated filling of the next to the outermost energy levels are transition metals. They occupy a central block in the periodic table.
When these elements have five electrons on the outermost shell of electrons.
