The most powerful nuclear weapon in the US arsenal is the B83, a thermonuclear bomb with a maximum yield of 1.2 megatons. It is designed to be carried by strategic bombers like the B-52 and is one of the largest and most destructive nuclear weapons currently in service.
The largest megaton nuclear bomb ever built was the Tsar Bomba, developed by the Soviet Union in 1961. It had a yield of 50 megatons, making it the most powerful nuclear weapon ever detonated. Due to its immense power, the Tsar Bomba was designed with a lead tamper to limit its full yield potential.
The weight of a nuclear bomb can vary depending on its size and design, but they generally range from a few hundred pounds to several tons. For example, the "Little Boy" bomb dropped on Hiroshima weighed about 9,700 pounds, while modern nuclear warheads can be as small as a few hundred pounds.
Nuclear bombs are extremely powerful weapons that can unleash immense destruction by releasing energy equivalent to thousands or even millions of tons of TNT. The destructive power of a nuclear bomb is measured in terms of its explosive yield, which can range from a few kilotons to multiple megatons. The effects of a nuclear bomb blast can include devastating immediate destruction, intense heat, radiation, and long-lasting environmental impacts.
The Mark 7 nuclear bomb was the first "laydown" surface burst bomb used by the US military. It was designed during the Cold War and had a yield of approximately 20 kilotons. The Mark 7 was primarily intended for use by tactical strike aircraft.
Both the US and USSR had deliverable nuclear weapons in the 10+ megaton range by 1955.

No, no country has ever had a 100 megaton bomb in production. The USSR tested a device with a 52 to 58 megaton yield called the Tsar Bomba, that they claimed was designed for 100 megatons (it was tested in a reduced yield configuration for various safety reasons). But this test was mostly for propaganda purposes and the bomb was never stockpiled in either configuration. The US once stockpiled a missile warhead with a 25 megaton yield. The highest yield weapons in any country's stockpile now are in the 300 kiloton to 500 kiloton range, as it has been demonstrated that anything higher is not really militarily useful.
Doubtful.
US, who else?
In order to develop the A-bomb
