History of the element

In the year 1789 uranium was discovered by a German chemist known as Martin Heinrich Klaproth. He was the first person to isolate the element and its radioactive properties. The element he had discovered from pitchblende was actually uranium dioxide, and pure uranium was discovered by heating uranium dioxide with potassium in a platinum. Today it is mainly obtained from uranium ores such as pitchblende ,uraninite and much more.

Properties and uses of Uranium


1. Hard, Ductile

2. Malleable, Radioactive

3. Dense, and Silver-white


Uranium is a very important element because it led us to victory in the world war II. Being used in one of the two atomic bomcs.However it is used to provide nuclear fuel to generate nuclear power stations.It is also used in nuclear reactors and nuclear bombs.

3 compounds with the element

uranium hexafluoride (UF6)

uranium tetrafloride (UF4)

Uranium oxides (UO2)

*all of these compounds are ionic compounds because uranium is a metal bonding with a non-metal.

periodic table info.

Atomic mass- 238

atomic number- 92

number of protons- 92 neutrons- 143electrons- 92

symbol- U

group names and properties

uranium is on the actinides group in the f-sub level below the periodic table


  1. all are radioactive
  2. actinides are highly electropositive
  3. the metals tarnish readily in the air
  4. actinides combine directly with most nonmetals
  5. they react with boiling water or dilute acid to reduce hydrogen gas
  6. very dense metals with distinctive strictures, numerous allotropes may be formed

reaction type

Equation for the fusion of uranium- 4H-->He+2E (energy came from the sun

reaction type- synthesis

mole to mole ratio- 4H-1H,2H-1E

other fun facts

The half life of uranium 238 is about 4.47 billion years and that of uranium 235 is 704 million years, making them useful in dating the age of earth.
