As atoms get larger, they have a weaker grip on their electron shell. Remember that as indicated by Coulomb's Law, the attraction between opposite electrical charges is inversely proportional to the square of the distance between them. Whereas, the attraction increases in direct proportion to the amount of the electrical charge. So a larger atom has more protons in the nucleus, with which to attract electrons, but the increasing distance of the electrons from the nucleus will reduce the attraction to a greater extent than the increased number of protons is increasing it.
So, as noble gases get heavier, and their grip on their electrons weakens, they become more capable of losing an electron and therefore entering into chemical reactions of some kind.

Yes, helium is part of the noble gases family. The noble gases are a group of elements that are colorless, odorless, and have low chemical reactivity. They are located in Group 18 (VIII A) of the periodic table.
