What type of energy is released when one element decays into other element?
kinetic energy
What element creates Lead when it decays?
Thallium 204 turns into lead.
What element decays to form helium and francium?
Actinium 225Ac--------alpha (4He) + 221Fr
What is the first radioactive element that forms when uranium 238 decays?
The isotope 234 Th.
What type of nuclear decay does Uranium undergo?
Uranium has a different decay chain/series for its different isotopes. Uranium 238 for example first decays to thorium 234 through alpha decay while U235 alpha decays to thorium 231. Both have different half lifes which can be found on a natural decay series chart for the said element. The thorium in either case then beta decays to another element.
Why an element call radioactive?
it is unstable and decays to another element
An element that decays to another element over a period of time is?
A property of that element. An unstable element. A radioactive element

What is it called when an atom decays and become another element?
Radioactivity
What happens when radioactive element decays?

What is produced when a radioactive element decays?
Energy, various sub-atomic particles, a different element.
What element creates Lead when it decays?
Thallium 204 turns into lead.
What is a decay chain?
One element decaying into another, which decays into another
What gas is produced when radium decays?
The extremely dangerous Radon (my favorite element).
If uranium decays is it a chemical change?
No. It is a nuclear change, as the identity of the element changes.
