SNC 1D
- Element Poster Due!

- Review previously learned trends in the Periodic Table.
Examples: 1. Metals are towards the left and tend to lose electrons.
Non-metals are towards the right and tend to gain or share electrons.

2. Elements within a column (family) have similar properties.

3. Elements which tend to lose/gain/share only one electron tend to be more
reactive than those which need to lose/gain/share a larger number of electrons.

- Do the lab: Trends in the Periodic Table (drop lithium, sodium, and potassium into water).
- Homework: Read and attempt all questions on the lab sheet handout (Lab report due Thursday).

Don't forget: Chemistry Unit Test this Friday!
