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.
What radioactive emissions are not particles?
Gamma rays.
What is an unstable atom?
An unstable atom is a radioactive atom.
What is a radioactive atoms?
A radioactive atom is an atom that has an unstable nuclear force, and therefore either absorbs or emits a radioactive particle.
What has two protons and two neutrons and is identical to a helium nucleus?
An alpha particle, one of the possible emissions in radioactive decay.
What are the characteristics of a atom?
A radioactive atom is an atom of an element with an unstable nucleus.
What is the final result of radioactive decay?
radioactive isotope
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
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.
Where do gamma rays originate?
by radioactive source
