Organization of Matter

In this brief video, students review the concept of an atom and its constituent parts (proton, neutron, electron). As well, students are reminded of the difference between ions, isotopes, and atoms and are expected to recall these concepts from the past. A note about polyatomic ions is included and students should proceed into the Chemistry 11 curriculum with full knowledge of these topics.

Learning Goals:

To define the atom as the basic unit of the molecule
To define an element as a pure substance made of a single type of atom
To be able to describe the position and electrical charge of the elementary particles in an atom (proton, electron, neutron)
To define the concept of ion
