When the unstable nuclei of heavy atoms radioactively decay they eject high speed particles this causes materials containing radioactive elements to a. increase in speed b become hotter c. cool down?
Sce1301
The energetic particles (either electrons, neutrons, or helium nuclei containing two protons and two neutrons) are absorbed by other nearby atoms. This may cause those atoms to break down and radiate other particles. Then eventual end result is always heat.

What gives off alpha particles?
Alpha particles are a type of particle of radiation that is emmited by certain radioactive materials. The materials that give off Alpha particles are called ''Alpha emitters.''
What happens to atoms that are radioactive?
Its nucleus emits radioactive particles continuously.
Radioactive particles stirred up after a nuclear explosion?
fallout, a mixture of debris picked up by the updraft in the mushroom cloud and condensed vaporized bomb materials.
How can radioactive particles create ions?
by ionising them
What the meaning of radioactive?
Any substance which is emitting ionizing particles is radioactive. An example is the metal called Plutonium.
What gives off alpha particles?
Alpha particles are a type of particle of radiation that is emmited by certain radioactive materials. The materials that give off Alpha particles are called ''Alpha emitters.''
What does radioactive materials and electricity have in common?
Electrons. Electricity is composed of free electrons and some radioactive decays emit electrons (beta particles)
What is radiopaque?
materials that emit high-speed particles and energy-containing rays from the interior of their matter.
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.
What is the name for the emission of rays and particles by a radioactive material?
The name for the emissions of rays and particles by a radioactive material are called radioactive decay. There are many different types of radioactive decay that emit different rays and particles.
What is meant by the word radioactive?
emits radioactive particles.
What is radio active material?
Radio active material that occurs naturally where human activities exposure to ionizing radiation are naturally-occurring radioactive materials, or NORM. They include uranium and thorium. Radioactive materials are mainly used in engineering and science departments. This type of material emits gamma rays or particles that as radioactive energy.
How can water become radioactive?
Yes they all are A small percentage of each element in all existence is radioactive and some elements are nearly 100% radioactive if not exactly 100% radioactive, so encountering radioactivity in air, soil, and water is inevitable.
How does radiocarbon dating help scientists understand how old a fossil is?
Paleontologists can radioactively date a fossil by determining the amount of carbon-14 isotopes remaining in the specimen. Elements decay by half-lives, meaning that after one half-life, half of the sample's radioactive particles are gone.
What happens to atoms that are radioactive?
Its nucleus emits radioactive particles continuously.
Is aluminum radioactive?
Nearly 100% of aluminum found in nature is 27Al, which is not radioactive. There are traces found of radioactive 26Al, but they are not significant. Other, synthetic, radioactive isotopes of aluminum exist, such as 25Al.
Radioactive particles stirred up after a nuclear explosion?
fallout, a mixture of debris picked up by the updraft in the mushroom cloud and condensed vaporized bomb materials.
