hello,
Anyone could you please help me with this question:
The diagram represents some energy levels of the mercury atom.
0
-1.6
-5.5 Energy/eV
-10.4
charge of electron = 1.6 × 10–19 C
the Planck constant = 6.6 × 10–34 J s
speed of light in vacuo = 3.0 × 108 ms–1
1) A transition between which two energy levels in the mercury atom will give rise to an emission line of wavelength 320nm?
