A LOT!
The United States droped 3 Atomic bombs on Hiroshima in 1945. After that, the Japanese were living in hell. Atometrical (atom for short) Bombs contain very much power due to the contractoins of the protons and neutrons inside of an atom.

At first the Japanese did not believe that one bomb could create THAT much damage. After the second city was atom bombed, the Japanese surrendered rather quickly.
A single 1 MTon bomb will do it, or four 250 KTon bombs, or a thousand 1 KTon bombs, etc. However more smaller bombs can spread the damage wider than one large bomb.
The H-Bomb, or Hydrogen Bomb, has never been used in warfare- the bombs dropped on japan at the end of WW2 were ATOMIC bombs, which are not as destructive. The Hydrogen Bomb is very much more powerful than the atom bomb, and has only ever been exploded in tests. For full information, Google 'US Hydrogen Bomb' and see what comes up.
It was actually the lower yield MK-I Little boy bomb dropped on Hiroshima that did more damage.The higher yield MK-III Fatman bomb was accidentally dropped much further from its target (almost 2 miles away) and the blast wave was contained by the surrounding hills.
A hydrogen bomb is more destructive than an atom bomb. A hydrogen bomb releases much more explosive energy through nuclear fusion reactions, whereas an atom bomb relies on nuclear fission reactions. As a result, a hydrogen bomb can produce a significantly larger explosion and more widespread damage.

It depends on how much atoms/weight it has
Los Almos did much work but J. Robert Oppenheimer is called the father of the atom bomb
it can do beyound our imagination.
The bomb hit the room that held all the ammunition.

That depends on who is selling it, who is buying it, and whether or not it is a Black Friday sale at Walmart.
They knew almost everything. In order to make the bomb they had extensive knowledge about how the atom works and the results of radiation on people and animals. They knew what they were doing, then left it to the politicians to decide.
The term atom bomb is somewhat ambiguous. The more precise distinction that you are trying to make is between a fission (or uranium or plutonium based) bomb and a fusion (or hydrogen based) bomb. The process of nuclear fission releases a certain amount of energy, and the process of nuclear fusion, per nucleus, releases a much larger amount of energy. Hence, you can build much bigger bombs based on fusion (although they still contain fission bombs which are required to create the high temperature needed for fusion).
A hydrogen bomb (thermonuclear bomb) is more destructive than a regular nuclear bomb (fission bomb). Hydrogen bombs release much larger amounts of energy and have the potential to create significantly more devastation and damage.
