Nonsense, there are no hydrides in noble gases.
Helium, neon, and argon have not yet formed compounds.
Krypton, xenon, and radon can form a series of compounds with fluorine, such as krypton difluoride, radon difluoride, xenon difluoride, xenon tetrafluoride, xenon hexafluoroplatinate, etc.

I only know xenon difluoride, xenon tetrafluoride, xenon hexafluoride.
Among them, the outermost shell of the xenon atom does not satisfy the eight-electron structure, and it is more than the eight-electron.

There are seven noble gases, helium (He), neon (Ne), argon (Ar), krypton (KR), xenon (XE), radon (RN, radioactive), and gas (OG, radioactive). Among them, OG is a rare gas synthesized artificially, and the nucleus is very unstable, with a short half-life of only 5 milliseconds. <
There are seven noble gases, helium (He), neon (Ne), argon (Ar), krypton (KR), xenon (XE), radon (RN, radioactive), and gas (OG, radioactive). Among them, OG is a rare gas synthesized artificially, and the nucleus is very unstable, with a short half-life of only 5 milliseconds. Noble gases refer to gases corresponding to all group 0 elements on the periodic table, also known as noble gases.
At room temperature and pressure, they are all colorless and odorless monoatomic gases, which are difficult to carry out chemical reactions.

Chemical properties of noble gases: extremely inactive, inert elements that cannot form compounds.
Noble gases are colorless, odorless, tasteless, slightly soluble in water, and the solubility increases with the increase of molecular weight. The molecules of noble gases are all made up of single atoms, they have low melting and boiling points, and as the atomic weight increases, the melting and boiling points increase, and they can both liquefy at low temperatures.
Neon, argon, krypton, and xenon are obtained from air by gas liquefaction and fractionation, while helium is usually extracted from natural gas, and radon is usually separated by radioactive decay of radium compounds. Rare gases are mainly used in industrial applications in lighting, welding and space exploration. Helium is also used in deep-sea diving.
Noble Gas Compounds:
In the atoms of noble gas elements, the arrangement of electrons in the various electron shells reaches just a stable number. Therefore, atoms are not easy to lose or gain electrons, and it is difficult for them to chemically react with other substances, so these elements are called "noble gas elements".
Among noble gas atoms with a larger atomic weight and a higher number of electrons, the outermost electrons are farther away from the nucleus and are relatively weakly bound. If you encounter other atoms that attract strong electrons, these outermost electrons are lost, resulting in a chemical reaction.

Question 1: What is noble gas Noble gases, also known as noble gases, noble gases, noble gases, noble gases, noble gases or blunt gases, refer to group 18 (8a) elements on the periodic table (IUPAC new regulations, that is, the original group 0), at room temperature and pressure, they are all odorless, colorless, monoatomic gases, and their reactivity is very low. There are six types of naturally occurring noble gases:
Helium (He), Neon (Ne), Argon (Ar), Krypton (KR), Xenon (Xe), and radioactive radon (RN). UUO, on the other hand, is a synthetic noble gas, which is very unstable and has a very short half-life.
The characteristics of noble gases can be explained by modern theories of atomic structure: their outermost electron shell is "full" (i.e., it has reached the octagram state), so they are very stable, rarely undergo chemical reactions, and only a few hundred noble gas compounds have been successfully prepared so far. The melting and boiling points of each noble gas are very close, with a temperature difference of less than 10 °C (18 °F), so they exist in a liquid state only in a small temperature range.
Neon, argon, krypton and xenon can be obtained from air by gas liquefaction and fractionation methods; Helium is usually extracted from natural gas; Radon gas is usually separated by radioactive decay of radium compounds. In the industrial aspect, precious gases are mainly used in lighting equipment, welding and space exploration. Helium is also used in deep-sea diving.
If the diving depth is greater than 180 feet (55 meters), the nitrogen in the compressed air cylinder used by the diver should be replaced with helium to avoid oxygen poisoning and nitrogen anesthesia. On the other hand, because hydrogen is very unstable and flammable, helium is used instead of hydrogen in today's airships and balloons.
