The US, Russia, the United Kingdom, France, China, India, and Pakistan are known to have thermonuclear weapons ("hydrogen bombs"). North Korea has tested fission cores powerful enough to initiate a deuterium-tritium fusion reaction, and it's believed (though it's not known with certainty) that they have a (probably small) stockpile of thermonuclear weapons.
So, that's 7 for sure, 8 almost certainly, and then there's a 9th:
Israel certainly has the technology level and resources required to construct a thermonuclear weapon. However, Israel has never officially confirmed that they have such weapons, and they are a signatory to the Nuclear Non-Proliferation Treaty (though it's generally suspected that they either have, or could in very short order construct, thermonuclear devices).
In addition, the US has nuclear weapons physically stored in Belgium, Germany, Italy, the Netherlands, and Turkey. The US formerly had thermonuclear devices in Canada, Greece and South Korea as well, though these have now been removed. The breakup of the USSR left some of its weapons in Belarus, Kazakhstan, and Ukraine, but these have likewise now been transferred back to Russia.
South Africa at one time had six nuclear weapons, but I believe these were fission ("atomic bomb") weapons and not fusion ("hydrogen bomb") weapons and they've since been disassembled anyway.
A hydrogen or fusion bomb will be ten times more powerful than the original fission atomic bomb.
There is no such thing. The hydrogen bomb is a very complicated mechanism, not a chemical!
no such thing. maybe you meant hydrogen bomb.
A hydrogen bomb is approximately 4.87 times more powerful than an atom bomb. What makes these bombs so powerful is that hydrogen is an extremely inflammable and explosive gas. When the bomb is released, the special coating used on its shell captures tons of friction, which heats the bomb. Then the detonator button is pressed, and the bomb blows up. Also, if the bomb comes in contact with the ground, before the button is pressed, then the heat absorbed by the bomb will set fire to the hydrogen inside and blow the bomb up.

What size of Hydrogen Bomb? How many megatons? the biggest size of hydrogen bomb can done ...........
the hydrogen bomb, is a nuclear bomb
A hydrogen bomb is an atom bomb; just one that uses hydrogen.
The Hydrogen bomb.
The Hydrogen Bomb .
Unable to answer question without knowing yield. A hydrogen bomb can have practically any yield.
hydrogen bomb
the hydrogen bomb has never been used in war
A bomb that splits a hydrogen atom, which literally explodes the air.
The 50 Megaton "Tsar Bomba" hydrogen bomb tested by the USSR in 1961 is the strongest hydrogen bomb ever detonated. The 10 Megaton "Ivy Mike" hydrogen bomb tested by the U.S. in 1952 is the physically largest hydrogen bomb ever detonated.
