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 0.901.

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 0.0017837 .

8 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

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-54Neutrons-77Electrons-548 valence electrons

Xeon Characteristics

nonmetal

Density @ 293 K: 5.8971 g/cm3

Melting Point: -111.9 °C (161.25 K, -169.42 °F)

Boiling Point: -108.1 °C (165.05 K, -162.58 °F)

Density: 0.005887 grams per cubic centimeter

Xenon

Electrical Conductivity- S cm-1 Specific heat (100 kPa, 25 °C) 20.786

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-86Neutrons- 136Electrons-868 valence electrons

Characteristics

Nonmetal

Density @ 293 K: 9.73 g/cm3

Melting Point: -71.0 °C (-95.8 °F)

Boiling Point: -61.8 °C(-79.24 °F)

specific heat- 0.09 J g-1 K-1

Radon

specific heat- 0.09 J g-1 K-1

Ion: noneOxidation: 0Reactivity: noneCompounds: 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.
