Hi! My name is Bismuth and I am the 5th element in the Nitrogen group. I am a crystalline, white, brittle metal with a pinkish tinge. I am the most diamagnetic of all metals. My thermal conductivity is lower than any metal, besides mercury. I have a high electrical resistance.  I also have the highest Hall effect of any metal (that is, the greatest increase in electrical resistance when placed in a magnetic field). In Latin my name is: Bisemutum and in Greek it is: Wismuth probably meaning “white mass.” I was usually always confused in early times between tin and lead because of my resemblance to those elements. Claude Geoffroy showed in 1753 that I was distinct from these metals. Hobbyist by my crystal form which is made in the laboratory because it is unseen in nature.I am heavy and I resemble arsenic and antimony. I am available commercially and I’m usually found in nature as bismite (Bi2O3), bismuthinite (Bi2S3), and bismutite [(BiO)2CO3]. I am generally made as a bi-product of zinc, lead, copper, tin, silver and gold plants. Lead-free compounds of my element are found in cosmetics and medical procedures.

This is my crystal form. Aren't I beautiful?   -Bismuth

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.
