They react with hydrocarbons using a free radical mechanism, and one type was used to synthesize the first (*) noble gas compound with platinum.
One element from this group participates in the Auwers synthesis by interacting with the pi electrons of an alkene as part of an addition reaction, and these elements can bond with each other to form their "inter-" variety. They react with hydrocarbons using a free radical mechanism, and one type was used to synthesize the first (*) noble gas compound with platinum. It is the only group to have elements in all three states of matter at STP, and these elements have high electronegativity because they are one electron away from a complete shell. For ten points, identify this family of diatomic elements that includes astatine, bromine, and chlorine.
