The Periodic Table

Define the following terms. 1. Proton 2. Neutron 3. Electron 4. Nucleus

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

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

Many periodic tables look different but still contain similar information.

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).
