Q

Under what conditions was Bohr’s theory not perfect in relation to spectra?

A

When his theory was applied to atoms with more than one electron, it failed to account for many of the lines in the emission spectra of these atoms

Q

Bohr didn’t take into account the fact that electron’s had a wave motion, how did this affect his theory?

A

This meant his picture of an electron travelling in a precise path at a precise distance from the nucleus cannot be true

Q

What affect did Heisenberg’s uncertainty principle have on Bohr’s theory?

A

Heisenberg’s uncertainty principle was in conflict with Bohr’s theory, i.e. we can only refer to the probability of finding an electron in a region in space

Q

What could Bohr’s theory not explain in relation to spectra?

A

It could not explain the splitting of certain lines in emission spectra and did not take into account the presence of sublevels
