16A Chemical Bonds
Why do atoms form chemical bonds?
Materials
Most of the matter on Earth is in the form of compounds. Even when a
substance exists as a pure element, it tends eventually to combine with

other elements. For example, if you leave an iron nail outside in the rain,
it will quickly combine with the oxygen in the air to form iron oxide, better
known as rust. In this Investigation, you will build models of atoms and
discover one of the fundamental ideas in chemistry: how electrons are
involved in the formation of chemical bonds.

Reviewing atomic structure
Let’s review what you already know about atoms:
• A neutral atom has the same number of electrons and protons.
• The electrons occupy energy levels surrounding the nucleus.
• Since electrons are attracted to the nucleus, they fill the lower energy levels first.
Once a given level is full, electrons start filling the next level.
