Study Notes

Atomic Structure

  • Ernest Rutherford suggested a model in which electrons and protons are uniformly mixed throughout the atom, contradicting Thomson's model.

Rutherford's Experiment

  • Rutherford devised the 'gold foil' experiment to test Thomson's model.
  • He bombarded the gold foil with alpha particles (high-energy helium nuclei).

Results of Rutherford's Experiment

  • Rutherford observed that most alpha particles passed through the gold foil, but some were deflected or even bounced back, indicating the presence of a small, dense, and positively charged nucleus.

Fields of Chemistry

  • Physical chemistry is focused on the physical principles underlying chemical reactions.
  • Biochemistry is the subdiscipline of chemistry that deals with the study of living organisms.

States of Matter

  • Solids are characterized by fixed particles that are very close together with very strong interactions.
  • Gases are characterized by particles having a random arrangement, being far apart, and having essentially no interactions between them.

Gas Properties

  • Pressure is the force exerted per unit area by gas molecules as they strike the surfaces around them.
