The atomic bomb was created after many years of the study of atoms.
Lastly, this site will cover the testing of the first Atomic bomb.
The circles we see above represent atomic radii. To see the trend more easily, the image above only contains the main group elements. The radii increase from top to bottom and decrease from left to right. The increase going down each group is due to additional shells of electrons, which also decreases Zeff. This makes each element in a group much larger than the one above it. The decrease going across a period is due to a gradual increase in the effective nuclear charge (Zeff). The nucleus has a stronger hold on its electrons, so the radius decreases.
August 6,9 - Atomic bombs dropped on Hiroshima and Nagasaki....
Despite knowing Zeff, it is very difficult to determine the size of an atom, which is the size of the electron cloud around the nucleus of an atom. But because we can never know the exact location of an electron, we cannot actually specify the size of an atom. One way to get around this problem is to assume that the atom is a perfect sphere. We can then determine an atomic radius by measuring the nucleus to the edge of the spherical cloud of electrons. There are a variety of experimental and theoretical methods to determine or calculate the atomic radius for an element. Using these radii, going from left to right across the periodic table, the atomic radius decreases because effective nuclear charge increases. (Figure 4-11)

The Huge Atomic Cloud / The Mushroom Cloud Blowing Up The atomic cloud (mushroom cloud) produced just after the burst is one of the most intensive characteristics of the A-bomb explosion.
What were the effects of the Atomic Bomb?
Besides high mortality rates, retarded growth and development was also indicated. Most notable in those exposed within 1.0–5.0 km of ground zero were retarded stature, underweight, and smaller head circumference, a condition called microcephaly, one of the most pathetic aftereffects of the atomic bombings, especially when accompanied by mental retardation.
How can the answer be improved?
The use of "tactical Deep Earth Penetrating" nuclear devices have been a part of testing which very likely resulted the Psunami and the Earth-quake in Northern Pakistan [Ref.
