Question

Who invented the atomic bomb?

Answer 1

When the atoms whose nucleus are heavier and the atomic number of those atoms are higher, disintegrates into smaller pieces which have much lighter nuclei and the atomic numbers of those integrated particles are also less, they produce a huge amount of energy which could be weaponized when planted in a certain way.

Complete step-by-step answer: An atom bomb is a type of weapon which could be used to make a lot of destruction because it covers a huge area of impact. The working principle of an atomic bomb is based on the concept of nuclear fission.
Nuclear fission could be defined as a type of nuclear phenomena in which an atom of higher atomic number and mass number meaning heavier nucleus tends to disintegrate into smaller pieces until it becomes a stable nucleus with smaller atomic and mass number.
Another nuclear phenomena which is called the nuclear fusion, is when two lighter nuclei combine with each other in order to form a heavier nucleus.
The atom bomb was invented by Julius Robert Oppenheimer who was given the title of the “father of atomic bomb”. Julius Robert Oppenheimer was a theoretical physicist by profession and was also a physics professor at the California University, Berkeley.

Note: The term radioactivity and nuclear fission are two different terms and should not be interchanged with each other, as in case of radioactivity, an atom undergoes radioactive decay in nature in order to emit certain kind of radiations whereas in case of nuclear fission, the nucleus of an atom breaks down into smaller nucleus which has lesser nucleus weight and this process gives off a lot of energy which could be weaponized to create mass destruction.
