they do not exist as molecules because they are noble gasses; as in they already have 8 valence electrons and therefore do not need anymore to have a full outershell. they rarely ever bond to anything because they are already stable and do not need to bond to have 8 valence electrons as most elements do when they become ions.
The gases that you listed are nobel gases and thus have a full octet of electrons making them very stable. In order for bonding to occur they would have to give or take additional electrons making them unstable. This is because of some rather advanced physics but just think of it as the atoms are happy that they have 8 electrons and don't want to change that thus don't want to bond with anything.
There are six noble gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). 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.
They are in the Group VIII Periodic Table (noble gases); therefore they have 8 valence electrons; this is a stable configuration.
Noble gases are chemically inert and do not combine with alkaline earth metals. However, xenon will combine with highly electronegative elements like fluorine and oxygen forming compounds like XeO2, XeO3, XeF4, XeF6, XeOF4 etc.
Noble gases, such as helium and neon, typically do not combine chemically with other elements due to their stable electron configuration. This stability makes them unlikely to form compounds with other elements.
Noble gases have completely filled electronic configuration and hence they are chemically inactive / inert / do not form bond with other elements.
Noble gases are chemically inert, meaning they are generally non-reactive with other elements. This is due to their stable electron configuration, with a full outer shell of electrons. This makes noble gases very useful in applications where a non-reactive atmosphere is required.
Noble gases are already stable because they have a full outer electron shell, making them chemically inert and unlikely to react with other elements.

Yes, because they are extremely hard or impossible to chemically combine with other elements.
Noble gases, such as helium and neon, typically do not combine chemically with other elements due to their stable electron configuration. This stability makes them unlikely to form compounds with other elements.
Noble gases are elements that rarely combine with other elements due to their stable electron configurations. This group includes helium, neon, argon, krypton, xenon, and radon. Noble gases are generally inert and do not readily form chemical bonds with other elements.
Noble gases have completely filled electronic configuration and hence they are chemically inactive / inert / do not form bond with other elements.
The noble or inert gases.
Group 17 elements are called halogens, which include fluorine, chlorine, bromine, iodine, and astatine. Group 18 elements are called noble gases, which include helium, neon, argon, krypton, xenon, and radon.

in nuclear fusion i assume it is theoretically possible to combine any elements but in terms of chemical bonding, no some elements ie noble gases are very nonreactive, though the heavier noble gases do form compounds with oxygen and fluorine.
No, the noble gases are generally chemically inert and are not considered chemically active. Solid elements in other families, such as the alkali metals or halogens, tend to be more chemically active due to their reactivity with other elements.
