Why does radioactive source give out radiation?
Radioactive decay happens when an unstable atom cannot hold itself together, and pieces of it fly out. The pieces include the emissions we call radiation.
If a substance is radioactive is its compound radioactive?
Yes. A radioactive atom is a radioactive atom. If that atom exists as a single atom and is uncombined and it is radioactive, it's radioactive. If that same atom is chemically combined with another or other atoms, it's still radioactive. It's just that simple.
True or false unstable atom that decomposes and emits energy is called retroactive?
No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
What radioactive emissions are not particles?
Gamma rays.
What are the characteristics of a atom?
A radioactive atom is an atom of an element with an unstable nucleus.
Where does heat originate from the earth?
Underground - from radioactive decay.
Which radioactive emissions is not a particle Alpha Neutron or Gamma?
Gamma.
What are the radioactive emissions that have the greatest penetrating power?
Gamma rays
What happens to a radioactive atom after it has emitted its radiation?
The initial atom is transformed in another atom.
Is a radioactive atom always an isotope?
No, not always.
What is the term for an atom the decays?
unstable, radioactive
What happens during a transmutation?
Transmutation is a what happens when a cellular change occurs in an atom. This mutation will occur in an atom if it is unstable as a way to stabilize itself.
