radioactive


What word is given to describe substances that give off high energy particles?

Radioactive substances give off high-energy particles through the process of radioactive decay. These particles can include alpha particles, beta particles, or gamma rays.


What particles does americium give off?

Americium emit alpha particles and gamma radiations.


Which are the two important particles in an isotope?

The atomic particles of an isotope are the proton, electron and neutron


Do isotopes that decay really disappear explain?

They don't so much disappear as become converted to a different isotope - as they throw off particles. If you took the remaining material and added the mass of the particles released as radiation, you should still get the same mass as the original material before the radioactive decay.


What is the process in which one isotope changes to another isotope?

The process in which one isotope changes to another isotope is called radioactive decay. During this process, the unstable nucleus of an isotope emits radiation in the form of alpha particles, beta particles, or gamma rays to transform into a more stable isotope. The rate at which radioactive decay occurs is measured by the isotope's half-life.


An unstable isotope with extra energy in the nucleus?

An unstable isotope with extra energy in the nucleus is a radioactive isotope. This extra energy causes the nucleus to undergo radioactive decay, emitting particles or gamma rays in order to become more stable. This process can involve the release of alpha particles, beta particles, or gamma radiation.


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 materials give off the most black carbon particulates?

An incomplete combustion give off black carbon particles.


Charged particles that are given off by the nuclei of radioisotopes as they decay are called?

Charged particles that are given off by the nuclei of radioisotopes as they decay are called decay products or radioactive decay daughters. Examples include alpha particles, beta particles, and positrons. These particles carry energy and momentum away from the decaying nucleus.


How much energy is in radioactive particles?

This depends for each isotope.
