PhySci Final Review 5: Matter

PhySci Final Review 5: Matter

By William Lovering

Elements are represented on the Periodic Table by their own symbol...

• Copper (Cu)

• Oxygen (O₂)

Elements

• Pure substance

• Made up of identical atoms

• Cannot be separated into a simpler substance by physical or chemical means

Atoms

• The basic building block of all matter.

• Made up of protons (+), neutrons (0), and electrons (-).

• Different atoms have different numbers of these energy particles

Compounds contain more than one element:

• Copper oxide (CuO)

• Methane (CH₄)

Homogeneous Mixtures

• blended evenly throughout

• you CANNOT tell the different substances apart

• more examples: creamy peanut butter, Gatorade, hand sanitizer

Heterogeneous Mixtures

• you can look at the different substances and tell them apart

• more examples: trail mix, crunchy peanut butter

Mixtures are NOT pure substances

Mixtures are not bonded together, therefore there is no chemical change. Each source of matter KEEPS its original properites!
