1. Reporting Category #1 Matter & Energy

2. Physical & Chemical Properties
Physical properties are properties that do not change the chemical nature of matter.
Shape, smell, and density
Phase changes: water turning to water vapor

3. Physical & Chemical Properties
Chemical properties are properties that do change the chemical nature of matter.
Color change, heat of combustion, reactivity with water and pH.
Iron Rusting

4. Physical & Chemical Properties
Any substance that contains only one kind of an atom is known as an element.
Each element is represented by a unique symbol. The symbol for each element can be found on the periodic table of elements.
Ex: aluminum (Al), hydrogen (H), calcium (Ca) , mercury (Hg).

5. Categories 3 Categories in the Periodic Table Metals Nonmetals
Metalloids

6. Metals Physical Properties of Metals: Luster (shininess)
Good conductors of heat and electricity
Chemical Properties of Metals:
Easily lose electrons
Corrode easily. Corrosion is a gradual wearing away. (Example: silver tarnishing and iron rusting)

7. Nonmetals Physical Properties of Nonmetals:
No luster (dull appearance)
Poor conductor of heat and electricity
Low melting point

8. Metalloids Physical Properties of Metalloids: Solids
Can be shiny or dull
Conduct heat and electricity better than nonmetals but not as well as metals

9. Physical & Chemical Properties
A compound is a substance formed when two or more elements are chemically joined.
Water, salt, and sugar are examples of compounds.
Letters, numbers, and symbols are used to represent elements and the number of elements in each compound.
Example: alcohol (C2H5OH), water (H2O),

10. Mixtures
Mixtures
Homogeneous mixtures are ones that have consistent properties. Think of them like a blended shake, which has the fruit cut so small and mixed up so that the shake has a specific consistency.
Heterogeneous mixtures have inconsistent and non-uniform composition, like a salad- it’s easy to see and separate the different vegetables.

11. Atoms Atom Tiny particles that compose most forms of matter
Simplest unit of an element
Smallest unit of matter
We all know atoms are what make up any substance. Atoms must have an equal number of electrons and protons with opposite charges in order to remain neutral and stable. Remember that electrons are always outside of the nucleus due to the energy of their motion.

12. Atoms

13. Atoms Atoms are made up of three subatomic particles:
Protons – positive charge located in the nucleus
Electrons – negative charge orbits around the nucleus
Neutrons – neutral charge located in the nucleus
