What are the elements of 17th group?

halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).

Is ytterbium flammable?

Possibility of Hazardous Reactions: Flammable in the form of dust when exposed to heat, spark or flame. May react with water under fire conditions liberating flammable hydrogen gas.

Is ytterbium harmful to humans?

Ytterbium and its compounds are not normally found in the human body. They are estimated to be of low to moderate toxicity. However, ytterbium is stored and treated as if it were a highly toxic chemical. Part of the reason is that metallic ytterbium dust presents a fire hazard, evolving toxic fumes as it burns.
