Organic compounds I: Simplest matter The Periodic Table

Atomic structure Define the following terms. Proton Neutron Electron Nucleus

Atomic structure 1. Protons: Positive charge 2. Neutron: Neutral 3. Electron: Negative Charge 4. Nucleus: Center of atom

Checking for understanding Why is it appropriate to say that atoms are the “building blocks” of all matter? Checking for understanding

What information does the periodic table provide? Many periodic tables look different but still contain similar information.

A square on the periodic table 1. Atomic Number Number of Protons Number of Electrons Number of Protons = Number of Electrons 2. Chemical Symbol: Letter(s) that represent the element (Always begins with a capital letter). 3. Atomic Mass: Number of Protons + the Number of Neutrons in one atom of the element (an average).
