We have a definition problem to handle here first: any bomb that gets its energy from the atomic nucleus (regardless of method) can be referred to as either an atomic bomb or a nuclear bomb.

There are two different processes by which the bomb can extract this energy:
  1. Fission of large unstable nuclei (e.g. Uranium-233, Uranium-235, Plutonium-239) into smaller nuclei.
  2. Fusion of small nuclei (e.g. Deuterium, Tritium) into larger nuclei (e.g. Helium). As Fusion can only happen at very high temperatures (i.e., 10,000,000K) it is often referred to as Thermonuclear Fusion.

Fission explosives are limited in yield by the amount of fuel that can be placed in the core of the device without risking criticality before it is desired to have the device detonate (if this happens the device will most likely just melt and kill anyone nearby). The theoretical highest yield of a pure Fission explosive is roughly 1 MTon, the highest yield pure Fission bomb tested was a US MK-18 airdropped as the Ivy King shot in 1952, with a yield of about 500 KTons. The core of the MK-18 was a hollow sphere containing FOUR CRITICAL MASSES of Oralloy (93.5% enriched Uranium-235). To prevent premature criticality the hollow of that sphere was filled with a boron/aluminum chain to absorb neutrons, that was only removed minutes before release from the bomber (this chain could NOT be put back in to safe the bomb).

Fusion explosives operate on a "Staged" principle: the Primary or 1st stage is a Fission explosive, which emits X-Rays used to compress and heat the Secondary or 2nd stage (the actual Fusion explosive). There is no criticality issue with Fusion, you can make the Secondary almost as big as you want with as much fuel as you want. If that isn't enough for the yield you want, additional Fusion stages can be added that are successively triggered by X-Rays from the previous stage compressing and heating the new stage. There is no theoretical limit on number of stages, and the only practical limit is what can fit in and be carried by the delivery vehicle. The highest yield Fusion bomb tested was the USSR AN602 airdropped as the Tzar Bomba (King of bombs) in 1961, with a yield of about 50 MTons. It was a 3 stage device, capable of a yield of 100 MTons if they had wanted to go all the way.

However, we have a complicating factor, almost no modern nuclear explosive is pure Fission or pure Fusion. It is often much cheaper, smaller, and lighter to build for example a miniaturized Fusion explosive than a pure Fission explosive of the same yield. So, many Fusion (aka Thermonuclear) bombs actually have far lower yield and extent of damage than some Fission bombs.
Thanks for the feedback!

Is a neutron bomb more deadlier than a nuclear bomb?

A neutron bomb is a nuclear bomb. Specifically a neutron bomb is a modified fusion (hydrogen) bomb. In a standard fusion bomb the fusion tamper is Uranium-238. This absorbs t

Is the nuclear bomb more powerful than the hydrogen bomb?

Nuclear bomb can mean either fission or fusion bomb. Hydrogen bomb means fusion bomb. The fusion bomb can be built with any yield one wants, just by adding more stages with mo

Which is more powerful napalm bomb or nuclear bomb?

Nuclear. Napalm is simply gelled gasoline fire bomb.

Why are nuclear bomb more hazardous then conventional bomb?

First, the amount of energy released is enormous. The most powerful conventional bomb has a few tons of explosive; 7 tons perhaps. The bombs used in Hiroshima and Nagasaki had

Which nuclear bomb did more damage?

Although the Hiroshima bomb had lower yield than the Nagasaki bomb, it did more damage because it: exploded closer to its intended APHiroshima is on flatter land than Nagasak

What more powerful a hurricane or nuclear bomb?

A single hurricane releases the energy (in the form of heat energy, and 10% of that converts to the form of mechanical energy (wind power)) equal to a 10-megaton thermonuclear

What is more powerful atomic bombs or nuclear bombs?

They are the same kind of bomb: bombs that derive their energy from the atomic nucleus. It just depends on design and how much of the design yield is from fission or from fusi

Why are thermonuclear bombs are more disastrous than nuclear bombs?

Nuclear bombs use nuclear fission of some heavy element, usually  uranium or plutonium. Thermonuclear bombs use the detonation of a  fission bomb to ignite the fusion of hyd

Which bomb is more dangerous a nuclear bomb or an atomic bomb?

A nuclear bomb and an atomic bomb are virtually synonymous. The twoterms are both used to refer to a nuclear weapon. Even Wikipediaagrees. The use of either term as a search a

How much stronger is nuclear bomb than an atomic bomb?

You are confused, a nuclear bomb is a general name covering both "atomic bomb" and "hydrogen bomb". A hydrogen bomb is typically higher yield than an atomic bomb, although it
In Physics

What is a thermonuclear bomb?

A thermonuclear weapon (Hydrogen bomb) is a weapon whose yield is derived mainly from fusion as its energy source. A nuclear weapon derives most of its yield from fission (som
