Ag, Db and Xe are chemical elements.
Noble gases are the six chemical elements of Group 18 of the periodic table and Xe is one of these.
Xenon has the chemical symbol Xe.
Xenon has nine naturally occurring isotopes: Xe-124, Xe-126, Xe-128, Xe-129, Xe-130, Xe-131, Xe-132, Xe-134, and Xe-136.
'What is 'xe' ??? If you mean 'Xe' (Xenon), then it is monatomic. It is listed in the Periodiuc Table in the Noble(Inert) gases Group. NB When writing chemical symbols. One letter symbols are ALWAYS a CAPITAL letter. Two letter symbols are , first letter is a CAPITAL letter and the second letter is lower/small case. This is the agreed international standard. Hence Xenon is 'Xe' ; NOT 'xe'.
Generally the noble gases, however xenon (Xe) has been found to create compounds with other elements, most often with F in XeF8
Xenon and neon are both noble gases.
Xenon (Xe)
Noble gases are the six chemical elements of Group 18 of the periodic table and Xe is one of these.
There are 18 Elements in the fifth period. They are Rubidium(Rb), Strontium(Sr), Yttrium(Y), Zirconium(Zr), Niobium(Nb), Molybdenum(Mo), Technetium(Tc), Ruthenium(Ru), Rhodium(Rh), Palladium(Pd), Silver(Ag), Cadmium(Cd), Indium(In), Tin(Sn), Antimony(Sb), Tellurium(Te), Iodine(I), Xenon(Xe).
The molecular compound in the list is SO2 (sulfur dioxide), as it consists of nonmetallic elements (sulfur and oxygen) held together by covalent bonds, forming discrete molecules. The other compounds (Xe, ZnO, and BeF2) involve metallic or ionic bonding rather than covalent bonding between nonmetallic elements.
Xenon has the chemical symbol Xe.
The symbol for an element is typically based on its name, so Xenon is represented by the symbol Xe. Symbol creation for elements involves various factors including language derivation, historical context, and chemical properties.
Elements that are extremely unreactive include: Platinum (Pt), Gold (Au), Helium (He), Argon (Ar), Xenon (Xe), Krypton (Kr). These are unreactive because: Platinum and Gold are the bottom two elements in the metals Reactivity series. The rest are inert gases which are all unreactive.
The chemical formula for radon is Rn, and the chemical formula for xenon is Xe. Both elements are noble gases and exist as single atoms in their natural state.
Xenon has nine naturally occurring isotopes: Xe-124, Xe-126, Xe-128, Xe-129, Xe-130, Xe-131, Xe-132, Xe-134, and Xe-136.

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.
