Helium, Neon and Krypton are 3.
Xe is the element xenon, which is a single element, not a compound. A compound, by definition is composed of two or more elements. Xenon rarely forms compounds at all, but in fact it can combine with some other elements such as fluorine.
it was found in 1896. you can not find them on the periodic table. you may find some, but often some are.
Xenon (Xe) has an atomic number of fifty-four. It is an odorless, colorless, noble gas that gives off a blue glow when electrified in a vacuum tube. Xenon is the most dense of all the noble gases and the most expensive. Xenon comes from the Greek word-Xenon, meaning stranger, and from the Greek word-Xenos, meaning strange. While inert and not readily reacting with other elements, xenon and oxygen compounds can be toxic and explosive. Xenon is found in the atmosphere of the Earth, the Mars and the Jupiter. Xenon found in meteorites also serves as an indicator of solar system formation. Several of xenon's unstable isotopes are produced from the fission of uranium and plutonium, and therefore result from a nuclear explosion.
Some common compounds of Xenon are...Xenon plantinofluoride (XePtF6)Xenon difluoride (XeF2)Xenon tetrafluoride (XeF4)Xenon hexafluoride (XeF6)Xenon trioxide (XeO3)Xenon oxytetrafluoride (XeOF4)Some of the common and/or cool uses for xenon is...Xenon is an odorless gas, a colorless gas, and emits a blue light when disturbedXenon has a melting point (-111.80oC), and a boiling point (108.13oC).The Earth's atmosphere is 0.0000087% Xenon.Xenon costs about $120 per GRAM!
Some isotopes of xenon do undergo radioactive decay to caesium.

It is found, bonded with oxygen, in quartz. But this is only in traces. It is also released by some springs.
Examples: hydrogen, helium, oxygen, fluorine, chlorine, argon, krypton, radon, xenon, neon, nitrogen.
By itself, xenon is not at all hazardous.
Noble gases: Ne (neon), Ar (argon), Kr (krypton), Xe (xenon), Rn (radon)
All elements except for Helium, Neon, will undergo some sort of chemical reaction. Even compounds of tghe inert/noble gases Argon, Krypton, Xenon and Radon have been made and isolated.
noble elements are the stable elements. They are found in group 18 in the periodic table.

NA and MG are bridge elements because some of the second period elements show a diagonal relationship with the third period elements. Other examples would be LI and MG.
some elements in the bottom of the periodic table man has not encountered yet, some are just theories or found on over planets or in space
