Today we know
of several naturally radioactive elements and
compounds. the best known of these is uranium becouse it is used in nuclear
reactors and nuclear weapons.
Chemistry is concerned with the exchange of electrons in the outside
regions of an atom, rathe than with what is happens in the core of an
atom, in tthe necleus. However, when working with radioactive elements,
scientists, and physicist need to understand the nature of the particles
that make up the atoms.
Radioactive elements vary greatly. All are quite rare; mast are metals.
But radioactive isotopes cannot be used in the same way as other metals
- to make new materials. indeed, if we use this way they could make
rather dangerous materials. Rather, radioactive elements are used for
their radioactive properties alone.
