When an atom gives away, receives, or shares electrons.
What is bonding?
A substance that cannot be broken down into a simpler subtsance.
What is an element?
A property or characteristic of a substance that can be observed without a chemical change.
What is a physical property?
Protons, neutrons, and electrons.
What are subatomic particles?

The tendency of an atom to attract electron pairs for bonding.
Electronegativity.
Two or more atoms bonded together.
Color, Volume, Malleability, Viscosity, Luster
What are examples of physical properties?
The study of substances, their properties, and how they interact.
