Nuclesr Equation Flashcards
What is radioactive decay?
A random process, unstable nucleus falls apart
What are the 3 types of radioactive decay?
Alpha Beta and Gamma
What is half life?
The time taken for a radioactive isotopes mass or activity to decay by half
Define isotopes
Atoms of the same element that have the same number of protons, but different numbers of neutrons
Describe the difference between alpha and beta decay
Alpha = helium nucleus, high ionising power, composed of two neutrons and two protons
Beta = electron, penetrating power, proton and electron but the electron releases
What is alpha decay and what is emitted?
Unstable nucleus shoots out a helium nucleus changing to another element
What is beta decay and what is emitted?
Beta ray is emitted releasing an electron changing element
