  1. Basics of matter Atoms -The building blocks of matter Atoms are composed of 3 types of particles: • protons (positively charged) • neutrons (no electric charge) • electrons (negatively charged) Atoms become different elements depending on the number and ratio of these three particles.

  4. An interesting fact: diterpene molecules are too heavy to allow evaporation in steam distillation, so are therefore rarely present in distilled essential oils!
