Noble gases or the inert gases as they are become know as have a full outer shell. It is possible to get different elements to fill in the last outer shell but it is extremely difficult to take electrons from a noble gas therefore when you ask what the difference is the question is perhaps not phrased properly because there is no difference they are two different categories. A noble gas is an element with a full outer shell and full outer shell is when an element has filled all of the max electrons in the last orbital.
Anion (if it has an almost-filled outer shell) or a cation (if only the outer S orbital is filled or partially filled)
An element reacts with another element by sharing electrons. The elements keep sharing electrons until both elements have a full outer shell.
Atoms often form ions by losing or gaining enough electrons to end up with a full outer shell. How many electrons are in a full outer shell for most atoms? Don't know? How about Googling full outer shell?
An atom will not normally form a chemical bond if it has 8 electrons already or in the case of hydrogen and helium, 2 electrons. A "full" valence shell has 8 electrons starting and period 2 on the periodic table. The elements with full valence levels are the elements on the far right family called the noble gases. The noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
If the outer orbital is not full of electrons, the atom is unstable. It will react with other atoms to fill its outer shell.
because they have outer electrons than can merge with other elements. all elements want to have full outer electron shells, and they only have a few outer electrons.

No. Elements that have a full outer shell of electrons are referred to as being stable. Cations are electrons that have a positive charge. However, when elements lose electrons to become stable, they are called cations.

A full p orbital contains 6 electrons.
Because the outer shell of electrons is full.
Argon has three full shells of electrons. Elements react to form bonds so that their outer shell is full. As Argon has a full outer shell it is unreactive
The evidence comes from the Noble Gases of the Periodic Table of the Elements. Electron octet rule for stability is based on the noble gases, which are also called the inert gases because they are so stable they rarely react with anything. Chemists have come up with the theory of electron orbitals to explain stability. These are referred to as S orbital, P orbital, D orbital, etc. When the outer most orbital contains an octet the electron orbital resembles the Noble Gases and hence why it is considered stable valence configuration.
