When a mineral spontaneously decays into subatomic particles?
Radioactive decay is the process through which unstable atoms disintegrate and emit radiation until they attain a stable configuration. New elements with reduced atomic number are formed.
Does radiation involve heat passing through particles?
Heat doesn't pass through particles. On an atomic or sub-atomic level, heat is the speed with which the particles are either vibrating or moving. Some kinds of radiation are related to the temperature of the particles that emit the radiation, other kinds are not.
What particles can thorium emit?
Alpha particles but also electrons and gamma radiations (Th 232).
What is the release of energy by particles of matter that have absorbed extra energy called?
Radiation. Different levels of energy dictate the type of radiation that is emitted. Extremely excited particles might emit visible light or even x-rays while particles that are not very excited might emit weak radio waves. This range from weak radiation to strong radiation is called the electromagnetic spectrum.
What energy produced by the vibrations of electrically charged particles?
Such particles will emit electromagnetic waves.
What do you understand by the term radioactive?
It refers to elements that undergo nuclear fission and, in the process, emit atomic particles (alpha and beta particles) and energy (gamma rays).
What particles give off high energy?
Radionuclide or radioisotope is a substance that give off high energy particles or rays as it disintegrates. They emit three types of radioactivity is alpha particles, beta particles, and gamma rays.
What substance does uranium and plutonium release?
The elements emit especially alpha particles.

What do radioactive materials do?
The atoms become some other type of atom. In the process, they emit some radiation, which contains energy. The radiation they emit typically include one or more of the following: alpha particles (helium-4 nuclei), beta particles (electrons or positrons), gamma rays, and neutrinos.
How are radioactive elements harmful?
They emit high energy particles, ionizing atoms in organic cells and disrupting many normal reactions in the cell.
What changes in a radioactive material to make it emit radiation?
Due to unstable atomic structures (or a weak nuclear force), radioactive materials release alpha particles as radiation.
Why those elements does not emit radiation whose atomic number is less than 82?
Because such nuclei have stable ratio of protons and neutrons, but some atoms having atomic no less than 82 are also radioactive.
Why elements in gaseous state emit radiation?
They do not! Most gases do not emit radiation.
