The Noble Gas Family “our family album” Mo, Gabbie and Kamile

Noble Gases Krypton, Neon, and Xenon are all brothers with Sir William Ramsay and Morris Travers as their parents. Their half brother is Argon who’s parents are Sir William Ramsay and Lord Rayleigh. Their cousin is Radon who’s parent is Friedrich Ernst Dorn.

Neon was born in 1898 in England by Sir William Ramsay & Morris Travers. Neon has 10 protons, neutrons and electrons. It is a non- metal and has a density of Melting Point: -249°C (-416°F) Boiling Point: -246°C (-411°F) Neon 8 Valence electrons Oxidation number is 0 Neon is not reactive. Pro: Neon doesn’t react, so there is no worry combining it. Con: Can cause dizziness, dullness, and suffocation if inhaled

Argon Pro: Used to fill incandescent and fluorescent light bulbs to prevent oxygen from corroding the hot filament. Con: If with a liquid it can cause frostbite Argon was born in 1894 in England by Sir William Ramsay & Lord Rayleigh. Argon has 18 protons and electrons. It has 22 neutrons. It is a non-metal and has a density of Valence electrons Oxidation number is 0 Neon is not reactive. Melting Point: -189°C (-309°F) Boiling Point: -186°C (-303°F)

Krypton Birthday: May 30, 1898

The Parents Sir William Ramsey Morris M. Travis

It’s a Non-metal! # of Protons: 36 # of Neutrons: 48 # of Electrons: 36

Characteristics Density: g/cm3 Boiling Point: °C Melting Point: °C Specific Heat: Heat Conductivity: W/cm K

Chemical Description # of Valence: 8 Oxidation Number: 0 Reactivity: None Possible Compounds: w/ oxygen  halides w/ hydrogen  oxides w/ hydrogen  hydrides “an odorless, colorless gas”

The Good and the Bad Used in: Lighting products Substitute for gas in fluorescent lights Is pretty safe Doesn’t react with other elements Dangers can cause: Suffocation If with liquid; frostbite

Xeon William Ramsay and Morris M. Travers discovered July 12, 1898 through the “study of liquefied air”. Xenon is a gas the Earth's atmosphere.

Xeon Protons-54 Neutrons-77 Electrons-54 8 valence electrons

Xeon Characteristics nonmetal 293 K: g/cm3 Melting Point: °C ( K, °F) Boiling Point: °C ( K, °F) Density: grams per cubic centimeter

Xenon Electrical Conductivity- S cm-1 Specific heat (100 kPa, 25 °C) J·mol- 1·K-1 Ion: None Reactivity: None Oxidation: 0

Xeon Used for powerful lamps and in spacecrafts for the iron thrusters, and as a general anesthetic If breathed in excessively without the right amount of oxygen it can be harmful due to the things its composed from.

Radon Friedrich Ernst Dorn, a German chemist, in discovered radon in 1900 while studying radium’s decay chain.

Radon Protons-86 Neutrons- 136 Electrons-86 8 valence electrons

Characteristics Nonmetal 293 K: 9.73 g/cm3 Melting Point: °C (-95.8 °F) Boiling Point: °C( °F) specific heat J g-1 K-1

Radon specific heat J g-1 K-1 Ion: none Oxidation: 0 Reactivity: none Compounds: Radon Fluoride

Radon Treatment of cancer; radiation, but not widely used do to the dangers If inhaled it is dangerous. Number one cause of lung cancer to non smokers. Invisible
