No, not in nature or most normal circumstances because it already has 8 electrons in its 'outer shell', so energetically it doesn't want to bond. However, in extreme conditions in the laboratory, compounds of Krypton have been made.
In an oxygen molecule, the two oxygen atoms are connected with a covalent bond.
No. Hydrogen and oxygen bond covalently.
Covalent bond
It's a chemical bond
It is, however, possible for krypton to hurt you. This isn't because the krypton is poisonous, but because of the lack of oxygen in the room. krypton takes up oxygen so if you were in a room full of it, you would suffocate.

Krypton isn't poisonous. If you breathe pure krypton for more than a minute or two, though, you would die as a consequence of oxygen starvation - but it is the absence of oxygen that kills you, not the presence of krypton.
nnnn

The bond is covalent.

Krypton is not considered harmful to humans in normal conditions, as it is present in trace amounts in the air we breathe. However, if krypton were to displace oxygen in an enclosed space, it could potentially pose a suffocation risk.
Krypton is a noble gas, and thus rarely forms any bond, ionic or covalent. When it does bond, it is usually covalent; however, krypton compounds are not found in nature and must be synthesized in a laboratory. Reports have also been made of ionic compounds with krypton, but these are only stable at extremely low temperatures.
The oxygen in the air is O2 and it has a covalent bond.

The question is very confusingly worded (and, in English, ungrammatical). How about I ignore it and just answer the question I feel like answering, which is "What will krypton react with?" Krypton will react with fluorine and oxygen under certain conditions. KrAr+ and KrH+ polyatomic ions have been investigated, and there's some evidence for a KrXe or KrXe+ species. Krypton apparently can also bond with nitrogen or carbon if you start with a krypton-fluorine compound and react it with a cyanide compound at low temperatures. That's pretty much it, so far as is currently known.
