Zach Reinhart Hernan Burgos Group 16 Chalcogen

Oxygen  Element Symbol-O  eˉ Configuration-1s²2s²2p 4  Element Classification-Non metal  Found naturally as O 2 and O 3 molecules  Used to breathe  State of matter-Gas  Chemical Properties-Very reactive oxidizing agent in combustion and respiration reactions.  Physical Properties- Melting Point: ºC Boiling Point: ºC

Sulfur  Element Symbol-S  eˉ Configuration-[Ne]3s 2 3p 4  Element Classification-Non-Metal  State of matter-Solid  Physical Properties-Has several allotropes, two main ones rhombic and monoclinic  Chemical Properties-Reactive in all forms  Most sulfur is used to make sulfuric acid  Naturally occurring found in areas around hot springs and in volcanic regions player_detailpage&v=F5jfRjzXLbE

Selenium  Element Symbol-Se  eˉ Configuration-[Ar]4s 2 3d 10 4p 4  Element Classification-non-metal  State of matter-Solid  Physical Properties-Melting Point: 217ºC Boiling Point: 688ºC  Chemical Properties-More light shined on it, better conductor of electricity.  Used extensively in electronics such as photocells, light meter, and light cells  Occurs naturally in nature through natural processes and human activities  Humans exposure to selenium is mainly through food, because it’s naturally present in grains, meats, and in cereal.

Tellurium  Element Symbol-Te  eˉ Configuration-[Kr]4s 2 3d 10 4p 4  Element Classification-Metalloid  State of Matter-Solid  Chemical Properties-Unusual property of combining with gold, gold normally doesn’t combine with many elements  Physical Properties-Melting Point:449.51ºC Boiling Point:988ºC  Tellurium was discovered by Franz Joseph Müller Von Reichenstein, a Romanian mining offical  Primary used as an alloying agent  Most often found in the ores sylvanite, calaverite, and krennerite

Polonium   Element Symbol-Po  eˉ Configuration- [Xe]6s 2 4f 14 5d 10 6p 4   Element Classification-Metal   State of matter-Solid   Chemical Properties-Radioactive   Physical Properties-Melting Point:254ºC Boiling Point:962ºC   Named after Poland   Used to eliminate static electricity in machinery   Usually produced by bombarding bismuth-209 with neutrons in a nuclear reactor, which forms bismuth-210 and decays into polonium-210 through beta decay
