Element Group:  Noble Gasses

I am most well known for my inert behavior,  although my cousins the Noble Gasses are all nonreactive and lazy.

But I am the laziest and most nonreactive. I’m not even a heat conductor, and because of this I am put between glass panes for windows to keep the cold out. I’m also used as an inert atmosphere in incandescent light bulbs to keep Oxygen (8) from eroding the hot filament. Arc welding is also one of my employers.

Like a few of my cousins, I have one compound with energetic Fluorine (9) and kingly Hydrogen (1); argon fluorohydride.

I am sleepy, lazy, nonreactive and inert. And that’s the way I like it.
