I am in the Pnictogon family.
My friends are Phil Phosphorous, Adam Arsenic, Alan Antimony, and Bob Bismuth.
My density is 1026 kg m-3
My melting point is 63.05 [or -210.1 °C (-346.18 °F)] K and my boiling point is
77.36 [or -195.79 °C (-320.42 °F)] K.
I am colorless, I have no luster, and my crystal structure is hexagonal.
I am also flammable in oxygen or air.
Some more stuff about me
My family and I have the same amount of valence electrons, 5.
We are mildly reactive.
Who discovered me and where I am found
Daniel Ruthorford discovered me by removing carbon dioxide and oxygen from air and found a new gas. Carl Scheele absorbed oxygen using a mixture of sulfur and iron with burning phosphorous and found an unknown gas also known as me!
I am found in various places such as air, earth's crust, and in the earth's atmosphere.
What I can do
I am commonly used in fertilizer, explosives (nitroglycerin), and "laughing gas" (anesthetic).
