What is the structure of an atom?

Protons, Neutrons and Electrons
o For each particle, know the electrical charge (+, - or neutral) and location in the atom.
o Why are atoms of elements neutral? (HINT: think of protons and electrons.)

Atomic Number
o What is it?
o Where is it in the boxes on the periodic table?

Mass Number (also known as Atomic Mass)
o What is it?

In general, metals have these properties:
In general, nonmetals have these properties:
More specifically, what properties do the elements in each of the 5 groups have? Be sure you
can remember the name, properties and location of each of the 5 groups.
