​ Oxygen Family The Oxygen Family The Oxygen family is made of Oxygen (O), Sulfur (S), Selenium (Se), Tellurium (Te), and finally Polonuim (Po). All except Oxygen are solids. Sulfur, Selenium, and Oxygen are nonmetals. While telluim is a silver metalloid and polonuim is a blue metal. Sulfur is a pale yellow and in it's pure form is tastless and oderless, Oxygen is a colorless gas, and Selenium is either grey red or black. Selenium and Telluim is also very rare to find while the others are more common to find in the enviroment. The outer electron shell contains six electrons

Oxygen

Atomic Symbol: O Atomic mass: 15.9994 Atomic Number: 8 Isotopes: 3 state: Gas Physical Properties Melting Point: -218.3°C Boiling Point: -182.9°C Density: 0.001429 g/cm3 Color: Colorless Solutibility: In water Malleable: Nonmalleable Ductile: Nonductile Electron configertion: Chemical Properties Flammablity: Dose not burn Conductivity very low Oxygen is a stable diaradical (an atom or molecule having two un paired electrons). Oxygen supports combustion Uses: Production of steel and plastic Compound: Carbon Dixode CO2 (helps photosynthesis). Compound Formula:C+O2=CO2 Who Discovered: Joseph Preistly Where it was discovered: England When it was discovered: 1774 Fun Fact:when a substance burns it combines chemically with oxygen no matter what. Picture:

Sulfur

Atomic Symbol: S Atomic Mass: 32.06 Atomic Number: 16 Isotopes: 4 state: Solid Physical Properties Melting point: 115.2°C Boiling Point: 444.7°C density: 2.07 g/cm3 color: yellow Solutablity: not soluble in water and is very soluble in carbon sulphide malleable: not mallaeble very brittle Ductile: nonductile electron configeration: Chemical Properties: reactivity with oxygen: when burning with oxygen it turns blue and relases a colorless gass. Flammablity: Burns between 248°C and 511°C Conductivity:highly conductive between the temperatures 0°C and 160°C Occurs naturalll by valcanos When burning the flame is the color blue Uses: Sulfur is used in detergents and fertlizer. Compound:most common is Sulfuric acide and is used to make battery acide. ompound fromula: S+O2= SO2 fun fact: Sulfur was referred to in the Bibel as Bromstone Picture:

Selenuim

Atomic Symbol:Se Atomic Mass:78.96 Atomic Number:34 Isotopes:5. state: solid Physical Properties: Melting point: 220°C Boiling point: 685°C density: 4.79 g/cm3 Color: grey, red, or black Solutability: insoluble in water Malleable: nonmalleable Ductile: nonductile Electron configeration: Chemical Properties: Conductivity:very low Flammability: not very flammable Reactivity with Oxygen: low When Burning it is bright blue. It combines easily with hydrogen, fluorine, chlorine, and bromine. Uses: Photograph toner Compound: selenuim sulfide it is used in shampoos Compound formula: Se+S2=SeS2 Who: Jons J. Berzelius When it was discovered: Sweden Where it was discovered: 1817 Fun Fact: Selenuim was named after the Greek Moon Goddess Picture:

Telluruim ​

Atomic Symbol: Te Atomic Mass:127.60 Atomic Number:52 Isotops: 5 Fun fact: the name comes from the latin word tellus meaning earth Picture:

Polonium

Atomic Symbol: Po Atomic Mass: 209 Atomic Number: 84 Isotopes: Thier is only 1 and it is not stable who: Marie and Pierre Currie Where it was discovered: france When it was discovered: 1898 Fun fact used for thermoelectric power Picture
