Did the Big-bang occur because of explosion of supernova star or a small mass of atom?

No one really knows the cause of the big bang as we cannot see any further back than the 3K microwave blackbody radiation, when matter and energy decoupled about 1 to 2 billion years after the moment of the big bang. No stars or atoms or even subatomic particles existed at the moment of the big bang. Not even space or time (as we understand them) existed at the moment of the big bang. All that existed at the moment of the big bang was an empty quantum vacuum (which is not allowed by Heisenberg's uncertainty principle). What happened to convert an empty quantum vacuum to our expanding universe full of matter and energy has generated many (mostly untestable) ideas:
- a quantum vacuum fluctuation produced one ultramassive particle/antiparticle pair, which decayed to less massive particles (losing antimatter in the process due to a broken symmetry) while space expanded dragging the particles with it.
- one form of string theory proposes infinite numbers of rapidly vibrating membranes of 4 dimensional spacetimes a few millimeters apart in the undetectable extra dimensions. The big bang began when our spacetime membrane and an adjacent spacetime membrane slapped into each other. The shockwave generated in each spacetime membrane is driving a big bang in each.
- another idea is spacetime foam, with billions (maybe infinite) big bangs happening as space expands dragging the bubble universes apart just faster than it expands the bubble universes (so we can never see any).
- etc.
Also it is very important to realize that the big bang is not just an event in the past starting the expansion, it is a continuing process that is happening now, it is the expansion of space dragging matter and energy along with it.

What elements were likely generated during a crab nebula explosion?
Since that was a supernova explosion, that would most likely produce all elements that occur naturally, except hydrogen (element #1).
Which star has the greatest probabilty of producing a supernova explosion?
There are many, as too there are many stars. Most supernova explosions are outside of our Galaxy and can occur at any time. So when a supernova explosion is witnessed, it's a rare event. Within our galaxy, or at least within visual with the naked eye, it has to be Betelgeuse. At only 600 light years from us, it is already experiencing the precursor to a supernova eruption. When it will occur - or more correctly - when will we observe it, is any ones guess, but it is expected within humanities lifetime.
What kind of storms do black holes and supernovas cause in Earth's upper atmosphere?
None for now. However, should a supernova explosion occur in our "neighborhood" (anywhere within a few thousand light-years in this case!), the strong radiation might have a severe impact on life on Earth.None for now.

Possibly the most cataclysmic event to occur in nature is?
After the Big Bang itself, we vote for the explosion of a 'supernova' or possibly a black hole.
Can a black hole stop a supernova?
A black hole is often the RESULT of a supernova explosion. When a massive star dies, the star explodes. The core of the star is crushed, while the outer layers of the star are blown away into space. This explosion is a nova or supernova. The early astronomers, seeing a burst of light where no star had ever been seen before, called them "nova stellarum", or "new star". When the core of the star is crushed by the explosion, the result is a neutron star or a black hole, depending on how densely the core is collapsed.
Why doesn't a supernova occur on earth?
A supernova can't occur on any planet. A supernova occurs when a very large star, at least 8 times more massive than the sun dies.
What type of explosion can occur at any moment?
An immediate explosion can occur at any moment.
How does the production of hot gasses cause an explosion to occur?
because hot gasses expand
What year Chernobyl explosion occur?
1986
What do you call an explosion that is about to occur at any moment?
immediate
What do you call an explosion that is about to occur any moment?
immediate
When does supernova occur?
If two stars begin to orbit. However, novae are more common that supernovae, so you can't really say if the result of a binary will be a nova or a supernova.
