How an Atomic Bomb works
By: Devan Brewer
History of the Atomic Bomb
• Although the atomic bomb was first introduced in 1945 the idea of
the bomb went back as early as 1895. At this point a scientist by the
name of Wilhelm Roentgen first discovered the X-ray by using a
cloud chamber that was capable of tracking charged particles. This
radiation was what fueled the atomic bomb. Next in 1898 Marie
Curie discovered the radioactive element radium which had the
capabilities of making a mass destruction similar to the long term
results of the bombings in Japan. Larger steps would be taken later
in the invention of the atomic bomb.
• In 1905 Albert Einstein developed the theories of the relationship of
mass and energy. Next from 1913 to 1938 the radiation detector is
invented. This is used by an American physician to diagnose heart
disease. Afterwards a demonstration is made on the ideas of nuclear
fission. Finally in July of 1945 The United States Tested the first
atomic device in a closed military area in New Mexico this was the
invention of the atomic bomb.
How it works
• An atom bomb works by starting a nuclear chain reaction on impact.
The explosion releases a large number of energy that is easily a
billion times the amount of a regular stick of dynamite. The reason
the atom bomb is so destructive is because of the nuclear reaction
that occurs in the bomb. The mass destruction that follows the
explosion of the bomb is created by its nuclear reaction.
• This Nuclear reaction occurs when the neutrons in each atom are
fired at other atoms that are extremely close to each other. These
atoms usually have very weighted nuclei and are mostly isotopes of
the elements uranium and plutonium. When a nucleus is hit by the
neutron it breaks in a smaller and lighter atom and this is known as
nuclear fission. This process repeats over and over again until a
chain reaction is formed. This nuclear chain reaction is what triggers
the explosion if the bomb and is what gives the bomb so much
power.
Nuclear Fission
• Nuclear Fission is the
process of elements
being broken up by
neutrons into smaller
elements. In this picture
the element uranium is
added with a neutron
which increases its
atomic mass. The
element then splits,
forming two new
elements( Baron an
Krypton) and two
neutrons.
The Atomic Bomb
• The atomic bomb was first
introduced in 1945. It is
triggered by a nuclear chain
reaction which is started by
nuclear fission the atom bomb
wiped out a good portion of
Japan and the effects of the
bomb are still in play today.
• "I have always condemned the
use of the atomic bomb
against Japan.“ – Albert
Einstein.
• This quote proves that Einstein
was against the bombings on
Hiroshima and Nagasaki.
