Big Ideas:
- Every element has predictable chemical and physical properties determined by its structure.
- The type of chemical bond in a compound determines the physical and chemical properties of that compound.
- It is important to use chemicals properly to minimize the risk to human health and the environment.
Overall Expectations:
A1 . analyze the properties of commonly used chemical substances and their effects on human health and the environment, and propose ways to lessen their impact;
A2. investigate physical and chemical properties of elements and compounds, and use varios methods to visually represent them;
A3. demonstrate and understanding of periodic trends in the periodic table and how elements combine to form chemical bonds.
