Sulfur hexafluoride is an inorganic, colorless, odorless, non-toxic and non-flammable gas
No, it is nonpolar. Hope this helps!
Covalent. Ionic bonds happen between Metals and Non Metals. Bonds between Non metals are covalent
It is SF6 but i don't know how you would represent the chemical bonding formula and how you would solve it. its a tricky one.
It's a very powerful greenhouse gas, but it's nontoxic and is used in a few medical applications.
