Flashcards do conjunto (9)
- 1Structure of the atomNegatively charged electrons orbiting a positively charged nucleus
- 2Rutherfords gold foil experimentThere is a dense positive core at the centre of the atom around which the electrons orbit
- 3Type of radiation used in Rutherford's experimentAlpha radiation
- 4Bohr modelThe nucleus was composed of protons and neutrons packed tightly together; electrons spin around it in fixed orbits
- 5Increase in electron ring radius corresponds with ...Increase in energy level
- 6When atoms gain energyElectrons jump from a lower energy state to the next energy level
- 7When electrons return to their original levelThey emit a photon
- 8Emission line spectraCaused by photon emission
- 9SpectrometerUsed to demonstrate line spectra
