My+Project+on+83+Bismuth

MY Bismuth Project By: Luca I Like Pie [|Bismuth] is a metal that is number 83 on the periodic table. Bismuth was and still is commonly confused with lead and tin because they look so similar. It was shown to be different between those other two elements in 1753 by French scientist, Claude Geoffroy. Nobody really knows when it was really discovered since it used to be confused with others. It’s made half by supernova clouds and half by small stars. That is some basic knowledge about bismuth.

All elements have an atomic mass and number. Bismuth has an atomic number of 83 and an atomic mass (mass of the atom) of 209. That means it, has 83 protons, a proton is a particle in the nucleus that has a positive charge. It also has 120 neutrons, neutrons are particles in the nucleus with no electric charge. Also it has 83 electrons those are particles outside the nucleus that have a negative charge. That is the information about sub-atomic particles in my element, bismuth.

Bismuth is a crystalline metal with a pinkish tinge. It turns solid at 25 degrees celsius and melts at 272 degrees celcius. It has the highest hall effect of any metal, which means it has the highest amount of resistance in a magnetic field. It also has the lowest thermal conductivity of all metal which means it can stand up to heat. Like a glove that you use to take food out of an oven with aso has high thermal conductivity.

People use bismuth in many different ways. It is used to produce medicine and other cosmetic materials. It is also used in fire detection and extinguishing systems that people use every day. You can find bismuth by digging underground, the same way you find other elements like lead, gold and, silver.
