Bohr’s Atom model
- Atoms consist of protons, neutrons and electrons.
- Protons (+) and Electrons (-) exhibit corresponding electric charges
- In a normal condition, an atom is neutral: same number of negative and positive charges.
- Electrons move in different shell-like paths around the core.
- This level is determined by the electron’s energy level.
- Shells are distinguished by the number of maximal electron capacity
- K: 2 electrons
- L, M: 8 electrons
- Electrons in unsaturated shells are called: Valence Electrons
- Electrons can move between shells through Absorption and Emission of energy.
