Study Notes
Rutherford's Model of the Atom
- Rutherford's gold foil experiment provided evidence for the nuclear model of the atom.
- Observation: Most alpha particles passed straight through the gold foil, indicating the atom has a lot of empty space. A few were deflected at small angles, indicating an interaction with a positive charge. A very small number were deflected straight back, suggesting a very concentrated positive charge in the atom.
- Conclusion: The atom consists of a small, dense, positively charged nucleus surrounded by negatively charged electrons.
- Limitations: Doesn't explain the stability of the atom. Electrons moving in a circular path would radiate energy, which it doesn't. Doesn't explain the arrangement of electrons in an atom.
-
Subatomic Particles:
- Protons: Positively charged particles found in the nucleus.
- Neutrons: Neutrally charged particles found in the nucleus.
- Electrons: Negatively charged particles that orbit the nucleus.
- The atom is electronically neutral because the number of protons (positive charge) is equal to the number of electrons (negative charge).
- The nucleus of an atom is very small compared to the size of the atom.
