Hey! I need a picture of nitrogen, not the atomic structure but nitrogen. Liquid nitrogen would work too.
The problem with getting a picture of nitrogen is that at 'normal'
temperatures, nitrogen is a gas. Not just that, but it's an invisible
gas. Nitrogen gas makes up about 70% of the air that you breath - you
see it every day.
Liquid nitrogen, however, is a bit easier to photograph. Liquid
nitrogen is basically just gaseous nitrogen that's been cooled down so
much that it's turned into a liquid. It's about 320 degrees F below
zero. But cool as that is, it still looks a lot like water, since it's
clear. What does look pretty interesting is the vapor clouds that you
get around it as it warms up and evaporates. You can find a lot
of pictures of liquid nitrogen on our site (since we use it at all of our shows), but here's just a few of my favorites:
