Transcript of Uranium

History of Uranium
Uranium was discovered in 1789 by Martin Klaproth,
a German chemist. It is found in the mineral called pitchblende. Uranium was named after the planet Uranus which was discovered 8 years before the discovery of Uranium.
Today we're going to explore
Martin Klaproth
Facts about Uranium
Uranium is a silvery-white colour, and weighs 18.95 grams per cubic centimeter. Its hard and rock like, and is found in the mineral called pitchblende. Uranium is solid at room temperature, and has melting temperature of 1135 °C.
Atomic Number
The Atomic number of an element is the number of protons in a atom.
The number of protons in an element NEVER changes.
The atomic number of Uranium is 92. It's 92 because that's how many protons there are in the atom.
Here is a diagram to help you get a visual of the location of the atomic number.
Atomic Mass
The mass number of an atom is the number of protons plus the number of neutrons.
Uranium has a mass of 238.03. This means that uranium has 92 protons and 146.03 neutrons.
Here is a diagram to help you get a visual of the location of the atomic mass.
Examples of different objects that use uranium
Atomic Bomb
Uranium Glass
Atomic Bomb
An atomic bomb is an explosion that releases nuclear energy.
On July 16, 1945 the first atomic bomb was set off. In August of 1945 another atomic bomb was set off, this time over Japan.
This is a video of the atomic bomb that was set off over Japan.
Uranium Glass
This type of glass glows under ultraviolet light.
The normal colour of uranium glass ranges from yellow to green depending on the oxidation state.
Certain things made of this glass are beads, marbles, and artistic glassware.
Uranium Marbles
Artistic Uranium Glassware
Thank you for watching this prezi I hope you learned just as mush as I did!!!!!!!!!!!
