they are allowed more by both SALT & START
Well first start of nuclear bombs has more common in physics that chemistry. Sense Chemistry is really assosiated with elemnts while the atom and it spliting is more assosiated with physics. The answer is easy in order to produce an atomic bomb you need uranium or plutonium which is part of chemestry. The fission process is more physic related
Bombs don't start wars, people do.
At the current time Russia has the most, followed closely by the US. These are controlled by limits set by START. The treaty allows Russia more and higher yield bombs because their ICBMs are slightly less accurate.
Start by assuming some 'facts' that would start a nuclear winter. How many bombs must be dropped to actually start a nuclear winter situation? For each bomb, how much dust is kicked up into the atmosphere? Of that, how much will stay in the upper atmosphere? How much sunlight will then be reflected, causing the cooling effect? Make all these estimations. Keep going from there.
Einsteinium-253, a radioactive isotope, is used in hydrogen bombs as a component in the initiation system. It helps to start the nuclear reaction by emitting neutrons when subjected to a high-energy source like conventional explosives. Its properties make it suitable for triggering the fusion reaction in thermonuclear weapons.
Impossible to say without knowing the yields, burst height/depth, and many other parameters. Although more bombs than that were built during the cold war, at no time has that many ever existed on earth. The peek in the 1980s before START was roughly 30000 functional bombs.
Nobody, the bombs were dropped on Japan in 1945 ending WW2. The "Cold War" didn't start until about 1947. Look up Winston Churchill's "Iron Curtain" speech.
Around 1916, before that they had no real bombs.
If you are asking which has the maximum danger, a hydrogen bomb is one type of nuclear bomb. In general, nuclear bombs can be fission (called atomic) or fusion (hydrogen) A fusion bomb is larger than an fission bomb, and actually uses a fission bomb to start the fusion reaction.
Yes--There are bombs that are magnetic.When two magnectics touch the bomb will go off. Sometimes it can start a charge. Bombs in general, no.
All US nuclear warheads at this time are miniaturized fusion bombs. None have yields of 1MTon or more. Most are between 300KTons and 600KTons. Exact size of stockpile is classified, but assuming (based on START limits) its about 5000 bombs of about 500KTon each, the US stockpile totals roughly 2,500MTons.I hope somewhere in there is the answer to your question.
