It's difficult to find something that doesn't exist. There's no credible evidence that there ever was such a bomb.
Yes, Russia has atomic bombs. But you have not yet asked a question.
Japan, after the US dropped atomic bombs on Hiroshima and Nagasaki in early August 1945.

no, you will know if they do
It didn't really. The war was all but over when Hiroshima and Nagasaki were bombed. It did ensure the Japanese surrendered earlier then they may have otherwise done. There were claims made that doing so saved many lives. Many people did not believe that at the time and more do not believe it today. The west knew that the USSR would be its main rival after the war and by showing that the west, the US in particular, had 'the bomb' was a demonstration to the USSR who had not yet developed the weapon.
No. The hydrogen bomb is the most powerful bomb in the world. The first atomic bombs split atoms of Uranium and/or Plutonium. Later development in theory and technology have made the Hydrogen bomb possible. This is in fact a 'normal' atomic bomb with a core of hydrogen. When the Atomic bomb goes off, this create an immense pressure on the hydrogen. This pressure (and heat) causes a fusion reaction of Hydrogen atoms. A 'relatively' small atomic bomb can trigger a quite large payload of hydrogen fusion material. Further developments of this massive destructive weapon has been to implement yet another core with radioactive material filled with more hydrogen. This inner core get super compressed by the first explosions, something of which drastically adds to the speed of material being consumed. Explosion being amplified tenfold. All such powerful devices are named 'nuclear' devices or nuclear bombs. Some are mostly a fission bomb, and others are mostly a fusion bomb. The fusion bombs are more powerful than fission bombs alone when comparing size and weight of 'stuff that go boom' Both fission and fusion bombs are considered atomic bombs, and their kind is among the most powerful devices known to man today. In theory, it should be possible to make an Antimatter payload. Something like a few grams could rival the energy released by the most powerful bombs today.
Nuclear bombs before the 60s were referred to as atom bombs, because the term Nuclear hadn't been discover yet. Nuclear bombs today, are generally Hydrogen bombs, or fusion bombs. They are significantly more powerful, able to places about the size of Rhode Island. Atom bombs,which were mostly uranium and plutonium, lack the destructive power of Nuclear or Fusion bombs.
The periodic table has about 118 elements, if that's what you're asking.
