Those sexy little atoms

So while studying for my test tomorrow (uh, actually today I guess), I picked up some interesting tidbits about a few elements. Pretty sure none of these will be on the test.

1) Of all the elements, sound travels the fastest through Beryllium. A whopping 12500 m/s!

2) Roentgenium has never been seen by the naked eye, but theorists say if someone ever saw it, it'd be gold.

3) Group 5, also called the Pnictogens, got it's name from a greek word meaning to stifle or choke. Funny since nitrogen is in this group and it makes up the majority of the atmosphere.

4) When heated, arsenic smells quite a bit like garlic.

And now I am going home...
