I think there are basically 2:

Fission (atomic bombs).  Fuels are usually either uranium or plutonium.

Fusion (hydrogen bombs) with a fission trigger system.

A third type you'll hear about is the Neutron bomb.  I believe it is a spacial case of fusion (hydrogen) bombs designed to maximize the release of neutrons. 

The bombs are often designed to explode in the air, or perhaps as deep penetrating "bunker busting".

Fortunately, after the second World War, people realised just how destructive a war using nuclear weapons would be, and they have not been used in war since then (but sometimes people have been used as guinea pigs).

So, in the past century or two, far more people have been killed by chemical-explosive bombs than nuclear-explosive bombs. Nobel (for whom the Nobel prize was named) thought that his new explosive would make mining much safer, and was horrified by the way it was used in warfare.

In the first World War, extensive use was made of chemical bombs, but this was considered too horrific, and banned. Nevertheless, occasional reports are heard of chemical weapons being used even today, on a small scale.

Despite the mass production of chemical weapons in WW 1, there were more people killed by the influenza virus than by the chemical weapons. A gas mask provided some protection against poison gas, but there was no protection against a virus.
The same has been true throughout the age of exploration - often the explorers brought new diseases for which the native population had no immunity, including smallpox, measles and sexually transmitted diseases. This decimated the population.

Today, despite treaties, various countries still have stocks of biological, nuclear and chemical weapons; all countries have bombs with high explosives.

Quote from: Albert Einstein
I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.

You may also see nuclear weapons categorised by how they are delivered:
  • They can be dropped from aeroplanes (as was done in WW2)
  • They can be carried on missiles (often called an Intercontinental Ballistic Missile, ICBM)
  • An ICBM may carry one or several small bombs, aimed at different targets
  • An ICBM could explode a missile outside the atmosphere, destroying electronic devices and shutting down the power grid in a target through ElectroMagnetic Pulse (EMP)
  • They may be carried on cruise missiles
  • Missiles may be carried on submarines, ships or trucks
  • They may be fired from cannons
  • There are reportedly some small enough to be carried by a single person, in a back-pack

When exploded near the ground, nuclear weapons create considerable radioactive fallout, which is blasted into the upper atmosphere, and is carried around the world on winds. This has left a radioactive imprint in the skeletons of people who have lived in the past 70 years.

PS: We can't really write your report for you, but you could start by searching on Wikipedia.
