  1. Group 16 (6A) and Hydrogen Alyssa Frost & Dan Nicoletta

  2. Members of Group 16 • Oxygen (O) • Sulfur (S) • Selenium (Se) • Tellurium (Te) • Polonium (Po)

  3. Oxygen Isolation • Pure oxygen (O2) is isolated by liquefying air and fractionally distilling the oxygen out of the solution

  4. Ozone • Ozone (O3) is an allotrope of Oxygen. • Ozone is produced by high voltage generators, electrical storms, and in Earth’s upper atmosphere. • Ozone is a pale blue gas with a distinctive odor

  5. Oxidation • Oxidation is when a substance chemically combines with Oxygen • The products of oxidation are called oxides • Oxides of metals can react with water to form bases • Oxides of nonmetals and gases can react with water to form acids

  6. Sulfur • Sulfur (S) is a pale yellow, tasteless, odorless, water-insoluble, brittle solid. • When Sulfur is melted and then cooled to 119 C, it forms an allotrope. • When it is cooled further to 95.5 C, it forms rhombic Sulfur, another allotrope. • Amorphous or “plastic” Sulfur is a third allotrope

  7. Hydrogen • Hydrogen is the most abundant element in the universe. • Even though it is very rare on earth, compounds of hydrogen are common. • They account for 1% of the earth’s crust. • Water is the most abundant hydrogen-containing compound.

  8. Three Isotopes of Hydrogen(natural occurring hydrogen composed of three isotopes) • The most abundant isotope: protium, commonly called hydrogen. • Protium (hydrogen-1) account for 99.98% of a sample. • Deuterium (hydrogen-2) account for 0.02% • Tritium, an unstable form of hydrogen, present in extremely small amounts.

  9. Hydrogen’s Position on Periodic Table • Hydrogen usually appears at the top of Group 1A. • H is not a metal and not a good conductor of heat and electricity. • Like the alkali metals, hydrogen reacts with the halogens. • Like the halogens, hydrogen reacts with the alkali metals. • All these factors make hydrogen unique.
