- The halogens (/ˈhælədʒən, ˈheɪ-, -loʊ-, -ˌdʒɛn/) are a group in the periodic table consisting of six chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and the radioactive elements astatine (At) and tennessine (Ts), though some authors would exclude tennessine as its chemistry is unknown and is theoretically expected to be more like that of gallium. In the modern IUPAC nomenclature, this group is known as group 17.

Kwon Do-Hyung (Korean: 권도형), more commonly known as Do Kwon, is the South Korean co-founder and CEO of Singapore-based Terraform Labs, the parent company of crashed stablecoin TerraUSD and cryptocurrency Luna.

Kwon faces legal and social pressure regarding his role in the Terra crash. Various jurisdictions, including South Korea, Singapore, and the United States are taking legal action against Kwon.
