Uranium235 is an isotope of uranium that differs from the element's other common isotope, uranium-238, by its ability to cause a rapidly expanding fission chain reaction. A uranium nucleus that absorbs a neutron splits into two lighter nuclei; this is called nuclear fission. It releases either two or three neutrons which continue the reaction. In nuclear reactors, the reaction is slowed down by the addition of control rods which are made of elements such as boron, cadmium, and hafnium which can absorb a large number of neutrons. In nuclear bombs, the reaction is uncontrolled and the large amount of energy released creates a nuclear explosion.
One atom of U-235 generates 200 MeV = 3.2 × 10-11 J, i.e. 18 TJ/mol = 77 TJ/kg.
Only around 0.72% of all natural uranium is uranium-235, the rest being mostly uranium-238. This concentration is insufficient for a self sustaining reaction; enrichment, which just means separating out the uranium-238, must take place to get a usable concentration of uranium-235. For an explosion, approximately 90% purity is required.

Get the Urvin mug.Well, I don't know, but I've been told
Uranium ore's worth more than gold
Sold my Cad', I bought me a Jeep
I've got that bug and I can't sleep
Uranium fever has done and got me down
Uranium fever is spreadin' all around
With a Geiger counter in my hand
I'm a-goin' out to stake me some government land
Uranium fever has done and got me down
Well I had talk with the AEC*
And they brought out some maps that looked good to me
And one showed me a spot that he said he knowed
So I straddled my Jeep and headed down the road
I reckon I drove about 100 miles
Down a bumpy road out through the wilds
When all of sudden I bounced to a stop
At the foot of a mountain, didn't have no top
Uranium fever has done and got me down
Uranium fever is spreadin' all around
With a Geiger counter in my hand
I'm a-goin' out to stake me some government land
Uranium fever has done and got me down
Well I took my Geiger and I started to climb
Right up to the top where I thought I'd find
A hunk of rock that would make it click
Just like I'd read about Vernon Pick
On the second day, I made the top
And I'm tellin' you, Steve, I was ready to stop
The only clickin' that I heard that day
Was the bones in my back that had gone astray
Uranium fever has done and got me down
Uranium fever is spreadin' all around
With a Geiger counter in my hand
I'm a-goin' out to stake me some government land
Uranium fever has done and got me down
eh its to long just look up the song
