Chemistry – The study of matter and atoms and the changes they can undergo
Atoms – The building block and basic unit of all matter
- Consist of a small charged particles
Subatomic Particles – Atoms contain charged particles
Nucleus Electron Cloud (rings)
Positive – Protons Negative – Electrons

3. Connection to the Periodic Table of Elements (p. 20 D)
Atomic Number – Number of Protons
- This is how elements are arranged on the periodic table
Neutral Atom –Protons = the number of Electrons
Atomic Mass Number – Number of Protons + Neutrons
- The total mass of the nucleus 6 C
Carbon
12.001
Atomic Number = # of Protons / Electrons
Symbol = 1st letter always capital
Atomic Mass = Protons + Neutrons

Warm up:
Atoms of the same element are alike / different.
Protons are positive / neutral / negative.
Protons are inside / outside the nucleus.
Neutrons are positive / neutral / negative.
Neutrons are inside / outside the nucleus.
Electrons are inside / outside the nucleus.

10. Matter Pure Substances Mixtures Element Compound Homogeneous
Has mass or weight
Takes up space (volume)
Cannot occupy the same space as other matter at the same time
Pure Substances
Has the same composition throughout
Can Occur Naturally
Mixtures
Formed when two or more substances are physically combined
Parts can be physically separated
Substances in a mixture retain their original properties
Element
Cannot be broken down into simper substances
Compound
Chemical combination of two or more different elements
Cannot be physically separated
Properties are entirely different properties of each element alone
Homogeneous
Parts of the mixture are evenly distributed
Heterogeneous
Parts of the mixture are not evenly distributed
