Mr. W introduces the importance of chemistry for biology students, explaining that living systems are chemical systems. The video covers the basics of atoms, including protons, neutrons, and electrons, and their charges. It explains the periodic table's organization based on atomic numbers and chemical properties. The video encourages students to engage with interactive learning materials on the website to reinforce their understanding.

Why is it important for biology students to understand chemistry?

• Because chemistry is more interesting.

• Because living systems are chemical systems.

• Because chemistry is easier than biology.

• Because chemistry is a prerequisite for biology.
