What were two problems that scientist encountered during their first discussions about making the atomic bomb?

1. Uncertainty about whether an atomic bomb would actually work. Some scientists were skeptical that it was possible to create a chain reaction that would release enough energy to cause an explosion. Others worried that the bomb might fizzle or produce only a small yield.

2. Fear of the potential consequences of using an atomic bomb. Many scientists were aware of the destructive potential of nuclear weapons and were concerned about the ethical implications of their use. Some scientists even argued that the atomic bomb should not be developed or used under any circumstances.
