Involves reactions where one element transmutes into another
Reactions that involve changes in the nucleus of an atom
Nuclear Chemistry
-
-
a (alpha) – readily absorbed, 2+ charge,4/2 He , large (relative) mass 6.65x10-24 g
- - either way of writing it is ok.
- - Relatively large mass in comparison to other types of radiation
- b (beta) – more penetrating, 1- charge, , less massive 9.11x10-28g
- - both ways of writing it is also ok. They are qeuivalent
- g (gamma) – highly energetic, no charge, no mass
-
Radiation
All types of radiation are highly energetic. This energy is transferred to any material the radiation contacts. This is the cause of the damage radioactivity creates.
-
natural change of isotope of one element to isotope of another element
Nuclear Reaction
-
Radon-222 to Polonium-218 by emission of an a particle
Make sure to find the atomic number to complete the reaction
Rn --> Po + He
-
Gamma Radiation
Most penetrating type of radiation
-
Radioactive Decay Series
A radioactive element decays to another radioactive element. This new radioactive element decays to another. This continues until a non-radioactive element is produced (and thus, the series ends) Each element that is produced after a decay in a radioactive decay series is usually radioactive in itself so it allows for another decay to occur. That’s why it is able to go through
