Anything after 'once' is academic
It is difficult to provide an exact number as the use of nuclear weapons would have catastrophic global consequences, potentially leading to nuclear winter and widespread devastation. It is imperative to prevent the use of such weapons to protect life on Earth.
As stated, the question is overly obvious; the world can be destroyed only once because once it is destroyed, there is nothing left to be destroyed, right? How many times could the same ceramic dish be shattered? More than once, but only if you are willing to glue it together again, and if the whole world were to be shattered, there would be no one left to glue it together again (unless you are expecting aliens from outer space to take an interest). However, you might have been thinking of the principle of overkill, that the nuclear arsenals of the world contain more weapons than would be needed to destroy the entire world. At a rough guess, the total inventory of nuclear weapons in the world is sufficient to destroy a dozen worlds at least (if we had a means of getting to other worlds, of course). But the Earth can be destroyed only once.
It is estimated that Russia has enough nuclear weapons to destroy the Earth multiple times over. A nuclear war involving Russia's full arsenal could lead to catastrophic global consequences, including nuclear winter and widespread destruction.
Einsteinium is the name of the radioactive rare earth metal that is named after Albert Einstein. It is a synthetic element with the atomic number 99 and symbol Es. It was first discovered during the nuclear weapons testing of the mid-20th century.
No, underground nuclear tests cannot alter the Earth's axial tilt. The axial tilt of Earth is determined by gravitational interactions with other celestial bodies and is not influenced by nuclear tests.
Yes, by a small amount, placing them in strategic locations that would make the earth's crust break up and covering the planet in lava
Yes they are very effective. Nuclear weapons are dangerous and really effective to destroy all life on earth. They are very powerful.
{| |- | The exact number probably remains highly classified. Both sides kept such things secret, while making it obvious to the other that the number was substantial. Many of the weapons have been destroyed, but more than enough remain to devastate life on Earth as we know it. |}
No, nuclear weapons do not have the capability to destroy the entire Earth. While they have devastating power and can cause widespread destruction, they are not capable of wiping out the entire planet.
Your questions asks for an opinion. My opinion is no. The knowledge of how to build a nuclear weapon is out there. There are too many people with different views and values for nuclear weapons to just go away.
{| |- | I'm sure the number is in the ten's of thousands. The exact number probably remains highly classified. Many of the weapons have been destroyed, but more than enough remain to devastate life on Earth as we know it. |}

The only nations to detonate nuclear weapons in outer space are the United States and the Soviet Union. During the heart of the Cold War, the United States and the former Soviet Union launched and detonated a combined total of over 20 thermo nuclear weapons in the upper atmosphere and near space region of earth in an effort to test the effects of launching an offense as well as countering an offense. Even during the Cuban Missile Crisis! Both governments do not give directions detailing how to detonate a nuclear bomb in space.
It is currently impossible to blow up the Earth using nuclear weapons as the planet is too large and the energy required would be immense. Additionally, detonating a large number of nuclear weapons on Earth could have catastrophic consequences for all life on the planet.
Eventually there were so many nuclear weapons, total destruction of the Earth was possible. The term "Mutually assured destruction (MAD)" was used to describe the resulting holocaust.

No, there are not enough nuclear weapons in existence to knock Earth off of its orbit. The force required to move a massive object like Earth would be astronomical and far beyond the capabilities of any known weapons. Earth's orbit is stable and not easily disrupted by human actions.
