Term | Definition |
---|---|
Bohr's model (solar system model) | energy levels / atoms absorb and emit light as electrons move energy levels |
When do atoms absorb energy? | moving to higher energy levels |
When do atoms emit energy? | moving to lower energy levels (also releases light) |
Modern quantum mechanical model | electrons in electron cloud and exist in orbitals |
What causes an atomic emission spectrum? | going from a higher energy level to a lower energy level |
Why does each atom have a unique spectrum? | the pull go the nucleus is different for each atom due to the protons and the electrons |
