What is an unstable isotope?
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
What are the isotopes that give off energy and emit particles are known as?
Isotopes that emit particles and give off energy are known as "radioactive" isotopes. The particles they emit generally come in the form of α-radiation i.e α particles (helium nucleus), and ß-radiation, i.e. ß-particles (electron or positron). Some small amount of neutrons may be emitted by an isotope as a byproduct of α-radiation. The primary energy emitted by radioactive isotopes is gamma radiation and heat; the heat comes from the effect of α-, ß and gamma radiation being absorbed by the surrounding materials.
What is the difference between radioactive and non-radioactive isotope?
Radioactive minerals are unstable and emit radiation at a constant rate. They also have half lives and lose energy overtime. Nonradioactive minerals are stable, and by there own are incapable of emitting energy.
Why synthesized isotopes emit alpha and beta particles?
All radioactive isotopes are unstable and they decay to a stable isotope emitting particles.
Is actinium a very powerful source of alpha radiation?
Yes, the isotope 227Ac emit alpha and beta radiations; all the isotopes of actinium are radioactive and emit radiations.
Why are some isotopes called radioactive?
These isotopes are unstable and emit radiation.
What are isotopes considered radioactive?
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.

When do radioactive isotopes occur?
A radioactive isotope is an unstable atom which emit radiations as alpha, beta, gamma, neutrons, positrons etc.
What eventually happen to all radioactive isotopes?
They emit particles, electromagnetic radiation, or both.* Apex*
What are two types of beta decay for radioactive elements?
Some isotopes emit an electron on decay, others emit a positron (anti-electron).
Why is uranium considered radioactive?
Uranium is considered a radioactive chemical element because uranium (all the isotopes) is unstable and emit nuclear radiations.
What are atoms that emit particles and energy from their nuclei?
radioactive
Why can radioactive isotopes be followed through a chemical reaction?
They emit radiation that can be detected with various radiation measurement tools. Usually the isotopes will be in only one of the products of the chemical reaction, making it radioactive and the others nonradioactive.
