Atoms and The Periodic Table

Topic: Chemistry Aim: Explain how elements are classified in the Periodic Table of Elements. Do Now: next slide HW: Atoms, Elements, Compounds and Mixtures.

The Periodic Table 8.5C: Interpret the arrangement of the Periodic Table, including groups and periods to explain how properties are used to classify.

 Elements are arranged according to atomic number  Number of protons  Not atomic mass.

There are three states of matter: gas, solid and liquid All matter is made of atoms An element is made up of one type of atom A molecule is a combination.
