Hi! My name is Antimony and I am the fourth element in the Nitrogen group. I am an extremely brittle metal with a flaky and crystalline texture. I have a metallic lustre and a bluish white color. I do not have reactivity to air at room temperature but, when heated with formations of white fumes I burn brilliantly. I am used in flame-proofing ceramics, a wide variety of alloys, rubber, electronic, enamels and ceramics.

One thing is that I am a poor conductor of heat and electricity. My compounds and I are very toxic elements and I am usually found with other minerals. You don’t need make me in a laboratory because I am commercially available.

I was founded by Tholden in 1450 and was only known to be a metal by the beginning of the 17^th century. No one is really sure on how my name came to be, but some people believe that it may have come from the Greek words “anti” and “monos” which approximately means “opposed to the solitude.”

This is me in a tube.

This is a native massive me with oxidation products.
