Hi there, in this question we are being asked about bohr's model of the atom.
00:07
And of course this model worked for the hydrogen atom, but it kind of fell apart when we started looking at atoms that had more than one electron.
00:14
But his model said that we have the protons and neutrons of course in the nucleus as rutherford said, and then the electrons are found in these orbits of increasing energy around the nucleus.
00:38
And these are defined paths of certain energy, and so using this he could explain that electrons could jump up to a higher energy level and then fall back down either one energy level or two energy levels in this example, and therefore emit light of certain wavelengths, because they could not exist in the space between these orbits.
01:02
So as we look here we are looking for the false statement about bohr's model.
01:07
Well letter a says electrons cannot be between energy levels.
01:12
That is that is a correct statement, because bohr said they cannot be between energy levels, they can only be in these exact levels.
01:25
We know that now as quantized.
01:29
All right, letter b says electrons orbit the nucleus.
01:32
Well that's correct, that's what we were just talking about with our little diagram there.
01:38
Letter c says an electron's path is not known exactly...
