The atom bomb was invented by the brilliant research of a group of scientists in 1945, working on what was known as "The Manhattan Project". The lead scientist was J. Robert Oppenheimer.
to make the atom bomb seem less threatning.
uranium
Yes.
Fission and/or fusion.
Well, the technical explanation is very complicated, so I will make it more simple: there are the fission bomb, and the thermonuclear bomb. The fission bomb makes an explosion through the splitting of atom. Atom is the smallest measurement. There are neutrons and photons in a atom. But when you split the atom to make a big explosion, you do not use any atom. We usually use an atom of uranium-235. When the uranium atom is split, the normal amount of neutrons or photons does not come out. Then the neutrons release lots of energy! (Very simple explanation: A fission bomb is a bomb that uses energy from splitting uncontrolled atoms. And a thermonuclear bomb is just opposite to fission bomb, it gets energy from fusion of atoms to make a heavier one.
To make people's lives harder. ;)
The video uses animation and song to make the atom bomb seem not so bad.

Firstly to make the atom bomb in WW2. After that to make electricity

The atom bomb is a type of nuclear weapon. Nuclear weapons can kill entire cities, make air quality unsafe, and kill plants and animals.
