Nonmetals almost have a full outer energy level while metals have few electrons in their outer energy level.
No, they don't.
Noble gases are the gases in the rightmost column of the Periodic Table that have a full outer energy level. This is why the noble gases do not react with other elements readily. When an atom has a full outer energy level, it means that it has the maximum number of electrons in these outer shells, making it stable.
If the outer energy level is full, the element is said to be non reactive and inert. It is stable in nature.
Nope. They sure don't.

All of the Noble Gases, which are on the right side of the periodic table, have a full outer energy level. The elements that are Noble Gases are the following: Neon Argon Krypton Xenon Radon Ununoctium
Hydrogen is the only element in the first period to not have a full outer energy level.
yes, because its outer energy level isn't full
Inert I believe
The outer energy level is in the electron cloud surrounding the nucleus. Each ring that surrounds the nucleus is an energy level and contains a different number of electrons.
Neon is a noble gas, therefore it is stable meaning that its outer energy ring is full. It has 8 elections on its outer energy level. Check out the related link for a picture of a model of Neons atom.
