- 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.
- Stochastic terrorism (Wikipedia)
Stochastic terrorism refers to political or media figures publicly demonizing a person or group in such a way that it inspires supporters of the figures to commit a violent act against the target of the speech. Unlike incitement to terrorism, this is accomplished by using indirect, vague, or coded language that allows the instigator to plausibly disclaim responsibility for the resulting violence. Global trends point to increasing violent rhetoric and political violence, including more evidence of stochastic terrorism. A key element is the use of social media and other distributed forms of communications where the person who carries out the violence has no direct connection to the users of violent rhetoric.
