Transcript of Teri M Chemistry basics

Chemistry
Matter, Mass, and Weight
Concepts that you should
remember.
Atomic Structure
The nucleus contains:
Neutrons and Protons
Electrons flow around the nucleus in orbits.
The outer most electrons determine how an atom behaves.
Most common Elements
in living things.
Hydrogen
Symbol: H
Atomic Number: 1
Mass Number: 1
Oxygen
Symbol: O
