Basic ideas about atoms 2
Cards in this deck (3)
- 1Explain why the emission and absorption spectra are series of sharp lines, not as a continuous spectrumEnergy levels are quantised
*So they have specific frequencies of light/amounts of energy needed to reach them
*So only certain transitions are possible/allowed - 2Explain why this is more than one series of spectral linesElectrons can fall down to different energy levels
- 3Explain how lines are formed on the emission spectrum of an atom*Electrons absorb energy & jump up energy levels
*As they drop back down to lower energy levels, they emit energy in the form of light
*For each electron that falls, a line is seen in the emission spectrum
