Very difficult to answer - since most countries are extremely secretive about the amount of nuclear weapons they have stockpiled.
China is not a nuclear free zone. They have many nuclear weapons. Though China has a nuclear policy which states that they are not allowed to produce,fire, or give away these weapons.
India has 85-100 nuclear warheads, around 15-20% of them aren't active.
Actually it is good and bad. Nuclear energy can save many people lives but in can be used as nuclear weapons which are super dangerous. resulting in explosions.
There is no impact of weather on nuclear weapons. They are stored in secure facilities which includes shelter from the weather. Nuclear weapons however do have an impact on the weather. A nuclear blast sends dust and gas into the upper atmosphere where it blocks sun-light from making it all the way to the surface. The cumulative effect of many many many such explosions is feared to create a nuclear winter and promote the onset of a new ice-age.
A nuclear bomb can be made with any desired yield from about 10 tons to well over 50 megatons in one single bomb. These numbers are just for tested devices that worked, there is no theoretical upper limit on the yield of fusion based bombs.
less than 4000, more than 400, exact number classified.
Tens of thousands.
B53 nuclear bomb is nine megatons No public data is out on how large the largest megaton nuke really is but there are claims and reports that it is over 100 megatons.
You had better ask the Pentagon!
Around 400 nuclear warheads. China has the third largest nuclear arsenal in the world.
12, 250 China has the 2nd largest nuclear arsenal in the world.
The word "nuke" can mean a nuclear power plant or a nuclear weapon.As of January 2013, there are 437 nuclear power plants in operation in the world.Because countries with nuclear weapons are secretive about how many they have, the exact number of nuclear weapons is not known. The Federation of American Scientists estimates there are more than 17,000 nuclear warheads in the world as of 2012.
there are many harmful causes of nuclear weapons because whole hiroshima was destroyed of it
