element
There is every known element floating around in outer space, since that is where most of the elements on Earth originally came from. When a star that is 25 times the size of our own sun goes supernova, it explodes and sends out most of it's mass (24 solar masses) into outer space.
Being radioactive lawrencium is dangerous.
This element is helium.
The most basic element we have discovered is hydrogen. If you are refering to matter. If not it is mostly photons.
The silver nitrate, but this is a dangerous compound.
plutonium
Space travel is statistically the most dangerous form of travel. Overall odds of fatality are approximately 1:120.

such an element is As, Arsenic.
You think probable to artificial radioactive elements considered transition metals.
it depends on which element
The process where an element turns to another is radioactive decay, and exposure to radioactivity is dangerous.
I would think it would either be a Hyper Nova or a Quasar
no.
Humans, because we are not adapted to survive in space without technology and protective gear. The vacuum of space, extreme temperatures, and lack of oxygen make it a very dangerous environment for us.
Being radioactive lawrencium is dangerous.
is the element dangerous on its or is it generally stable
