Guided Notes
Key concepts students will learn:
- •
Water is a polar molecule, meaning it has an uneven distribution of charge and is electrically neutral.
- •
Electrons spend more time orbiting the oxygen nucleus, making it slightly more negative, while the hydrogens become slightly more positive.
- •
Cohesion is when water molecules are attracted to themselves, while adhesion is when water molecules are attracted to other polar substances, leading to capillary action and high surface tension.
