That is unknown, sorry
how reactive is radon and will it combine with other elements
nuclear fusion
Yes it can
Tantalum
technetium forms with other elements to make compounds
Tantalum and carbon.

Vanadium, niobium and tantalum are transition metals.
Uranium combine with the majority of other elements; also uranium has alloys with the majority of metals.
For example halogens, carbon, oxygen, sulfur, other nonmetals.
no
Neon has completely filled orbitals. It is chemically inert and does not combine with other elements.
No. helium is chemically inert and does not combine with other elements.
nuclear fusion
inertness, non-reactivity
yes it does
fusion
