What is the Family name for elements that have filled energy levels and do not make compounds?

Nobel gases. They are stable elements in that they have complete outer shells, but they can be made to react with other elements to form compounds. For elementary chemistry, however, they can be considered inert.

Why does the elements of family 18 do not tend to form chemical reactions?
Because all the atoms of these elements in Family 18 have filled outermost energy levels.
Does helium mix with other elements to form compounds?
No. helium is chemically inert and doesn't form compounds as it has completely filled orbitals.
What family contains elements that will not form compounds metalloids halogens noble gases strong metals?
Remember a family is also a group, so 3A - 7A.
Because their outermost energy level are only partially filled some elements are highly?
Because their outermost energy level is only partially filled, some elements are highly reactive, I believe.
How come noble gases do not compounds readily?
Their outer energy levels are completely filled.
Which energy sublevel is being filled by the elements Rb to Sr?
5s
Which energy sublevel is being filled by the elements Ce to Lu?
4F
What is the basis for exceptions to the aufbau diagram?
some elements have unusual atomic orbitals
What ionic compounds and covalent compounds does argon form?
Argon is chemically inert due to the presence of completely filled orbitals. It does not react with other elements and hence does not form ionic or covalent compounds at STP.
Why are there only a few known compounds involving noble gases?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions. Mainly elements like krypton or xenon form compounds with highly electronegative elements like fluorine and oxygen
Same elements are highly what because their outermost energy levels are only partially filled?
reactive
For atoms of most elements the outer energy is filled when it has 8 electrons true or false?
true
