Answer:
Helium
Explanation:
Helium is most likely to undergo a chemical reaction because
- It has a complete electron shell, so it does not need any more electrons
- Its electrons are closest to the nucleus, so it is extremely difficult to remove them
The elements least likely to undergo a chemical reaction are:
Gold: Au
Silver: Ag
Platinum: Pt
They are located very low in The Reactivity Series and hence don't react with any other substance. That is why their market value is pretty high.
