A radioactive material is radioactive. Period. The atoms of radioactive material have unstable nuclei. If you combine them with other material, the radioactive material will remain unaffected as regards its radioactivity. Recall that radioactivity is related to the instability of atomic nuclei, and the atomic structure of atomic nuclei are (in general) not involved in chemical bonding. Chemical bonding doesn't affect the stability of the nuclei of atoms. If they are unstable, they will remain so whether the atoms are alone or chemically combined with something else.
No: The distinction between metals and nonmetals is a property of elements or mixtures of elements (alloys), but dinitrogen pentabromide is a compound.
When two metals are combined, they form an alloy, which is a solid solution of different metals. When a metal and a nonmetal are combined, they form an ionic compound through the transfer of electrons between the two elements.
When carbon and argon are combined, they do not form a compound. Carbon is a nonmetal element, while argon is a noble gas, so they do not easily react with each other to form a stable compound.
No: Iodine is not a metal at all, but a nonmetal. It is not necessarily radioactive, but has some radioactive isotopes.
FeO is not a nonmetal; it is a compound composed of iron (a metal) and oxygen (a nonmetal).
This is an oxide.
This is an oxide.

A covalent bond is formed. A molecular compound is formed.

Look at the periodic table of the Elements. Go to group three. All the metals down that list will lose 3 electrons with combined with a nonmetal to form an ionic compound.
Astatine is a radioactive, natural element and also a nonmetal similar to halogens.
When carbon and argon are combined, they do not form a compound. Carbon is a nonmetal element, while argon is a noble gas, so they do not easily react with each other to form a stable compound.

Yes, Rn is radon a radioactive nonmetal. But the symbol Rn does not stand for "radioactive nonmetal." Rn Radon has no stable isotopes, so yes it is always a radioactive nonmetal.
FeO is not a nonmetal; it is a compound composed of iron (a metal) and oxygen (a nonmetal).
