Front

These have an unstable nucleus that breaks down at a constant rate and can therefore be used to date/trace things (such as fossils or substances in the body):

Back

radioactive isotopes

Front

Back

compound

Front

This type of chemical bond involves the transfer of electrons from one atom to another, creating opposite charges that attract each other:

Back

ionic bond

Front

This type of chemical bond involves the sharing of electrons between two atoms:

Back

covalent bond
