Bohr basically just clarified specific stable energy levels and conservation of angular momentum and whatnot to explain spectroscopy. But his model is often referred to the Rutherford-Bohr model even in HSC so they are borderline the same model.
I got taught that as well but only briefly
Felt like I bloody redid English paper 2 with that one
Yeh I agree with that. A lot of the questions were just nonsensical, like 36, 31 and 26.
It was an answer in one of the past papers wasn't it? You should know at least 2 limitations for both Rutherford and Bohr. I doubt you need too much detail on the limitations. Just maybe one line of explanation IF it's a high mark question. For me the two simplest limits for Bohr is that his model only applied to the hydrogen atom, and it couldn't account for hyperfine splitting.
Could you also include the fact that electrons are in circular motion, and thus accelerating and should be emitting light. iirc bohr had a postulate that said that the electrons didn't do this, but he had no physical justification other than electrons had stable orbits in real life, so his model had to as well
yeah 1. unspported postulates (for now) 2. hydrogen only seem the most straightforward
Totally! I have that as a limitation for Rutherford. Bohr couldn't actually prove or explain his postulates. i.e He says no EMR is emitted when in a stationary state. But when asked to define a stationary state it's defined as when no EMR is emitted. His explination was very cyclical
Me too
I think schrodinger is just saying you can only look at electron orbits in terms of probability (hence the cat in a box thought experiment). Electron's don't occupy specific positions/orbits/energy levels, instead are defined by the probability that the electrons will occupy these spaces.
i just use my left hand for negative charges i.e cathode rays, singular electrons. Right hand for positive charges
right hand is for everything lowk except for negative charge or induced current where u just do the opposite. lenz law and negative is opposite to positive
Right hand for positive charges and left hand for negative charges. You can never go wrong. And current is a flow of protons so use your right hand.
ahh ok, including for motors?
yes definitely just know your advantages and limitations of the models
