Bismuth Science Facts 

Fact one 

Bismuth is very weakly radioactive; its only primordial isotope, bismuth-209, decays via alpha decay with a half-life more than a billion times the estimated age of the Universe. Bismuth can also be used in nuclear reactors and to make trans-uranium elements using a process called cold-fusion.

Fact two

Bismuth subsalicylate (‎C7H5BiO4) -sold under the brand names Pepto-Bismol and Kaopectate- is a well-known remedy for stomach aches and diarrhea. It works by decreasing the flow of fluids and electrolytes into the bowel, reduces inflammation within the intestine, and may kill the organisms that can cause diarrhea, according to the U.S. National Library of Medicine.  

Fact three

Bismuth is the 83rd element on the periodic table (hence the name) and it is located right next to lead which is element #82. 

Fact four

Bismuth has a heavier atomic weight than lead 207.2 (lead) compared to 208.980 (bismuth).

Fact five 

Most solar panels are made of silicon.  The silicon is made into something called "silicon wafers" which are used in solar panels.  The way solar panels works is, a small piece of silicon traps the light and extracts power from the light - which is the primary function of the silicon wafers.  Silicon removes and extracts infrared (invisible) light because of how small their gap is.   That being said, bismuth has a wider gap than silicon; the bismuth gap reaches farther into the spectrum of light and is able to pull power from visible light.  Visible light is produced by  things such as light bulbs, street lamps, etc. - any form of light that we can see with our eyes.  This makes solar panels made of bismuth more efficient.

Fact six

Bismuth's meting temp is 544.55 K (271.40°C or 520.52°F) which is what enables me to melt the metal on a standard electric burner.
