Atomic Structure

Atomic Structure. First off, what is an atom?. Atoms are the smallest parts to which an element can be divided. Atoms are the building blocks of all matter. How small is an atom?. An atom is so small that a penny contains about 2 x 10 22 or 20,000,000,000,000,000,000,000 atoms!!!.

The Atom

The Atom. Part 1. Inside the nucleus. Inside an atom. Atoms are made of 3 sub-atomic particles Protons Mass = 1 amu (atomic mass unit) Charge = positive Neutrons Mass = 1 amu (atomic mass unit) Charge = neutral (no charge) Electrons Mass = too small Charge = negative.
