There actually are simple... The nuclear bombs dropped on Hiroshima and Nagasaki were both designed to detonate several hundred metres above the ground. ... This is simply because a bomb that uses an impact fuze will transfer a lot of it's blast energy into the ground when it hits- which is wasted energy.

The most powerful fission explosion is achieved by using enriched uranium and plutonium atoms, which are unstable and radioactive. Atomic bombs (also known as A-bombs or fission bombs) produce their explosive energy purely through nuclear fission reaction.

Atomic bombs are made up of a fissile element, such as uranium, that is enriched in the isotope that can sustain a fission nuclear chain reaction. When a free neutron hits the nucleus of a fissile atom like uranium-235 (235U), the uranium splits into two smaller atoms called fission fragments, plus more neutrons.
