They have a flu outermost energy level.

Group 18 (noble gases), because there outer energy level is full
There are no "noble metals". The "noble" connotation for "noble gas" is that in society, the "noble" people don't interact with the average people. "Noble" or inert gases do not take part in any regular chemical reactions. The individual atoms don't form elements or compounds.
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).

octet
Noble gases do not naturally form chemical bonds because their valence orbital is full of electrons. Helium has 2 electrons, and the other noble gases have 8 electrons in their full valence orbital. This full shell makes them unreactive (they have high ionization energy and almost zero electron affinity). However, under special conditions in the lab, scientists can artificially synthesize noble gas compounds such as XeF6.

No. Noble gases exist in nature, and are chemical elements. These are the six noble gases: Helium (He) Neon (Ne) Argon (Ar) Krypton (Kr) Xenon (Xe) and the radioactive Radon (Rn)

Their outer energy shell is full of electrons and so it does not need to form a bond to fulfil this.
These are complete filled electron shells.

pretty much all elements will bond, but noble gases rarely do
Noble gases have a full outer shell, meaning that they have no valence electrons and have 8 electrons in their outer shell. If the outer shell is full they do not need electrons, so they would not want to bond with another element to form a compound.
