Guided Notes

3 key concepts

  • 1

    Water is a polar molecule, meaning it has an uneven distribution of charge and is electrically neutral.

  • 2

    Electrons spend more time orbiting the oxygen nucleus, making it slightly more negative, while the hydrogens become slightly more positive.

  • 3

    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.
