Question

PLEASE HELP!! MEDAL!!
The Quantum theory and the Bohr Model have both been used to organize atoms and their particles. Explain the main components to each model and provide a strength and weakness for each atomic model.

Well, quantum theory model, is based on the heisenberg uncertainty principle/quantum mechanics, which means that we can't know for certain both the position and momentum of an electron, so what this means is that we generally can't know exactly where an electron is, so that's why we have something called orbitals, where electrons are most likely to be found. the nucleus is positively charged of course in both models. Also consider that in quantum mechanics, electrons have properties of both particles and waves, so there's a duality here.

for the bohr model, electrons aren't found in orbitals but rather revolve around the positively charged nucleus like planets around the sun. of course this depiction is wrong because it's based entirely on a particle like behavior of electrons. if this were the case we would be able to calculate the position and momentum of the electron precisely, and use our understanding of physics to predict where exactly the electron will be. but the weakness in this model is implied here, if we could know all of these aspects of an electron then sure that would work if an electron completely behaved like a particle but it doesn't.

thank youuu @Photon336

Answer 5

You understand this better right? essentially these two models differ in the sense that one involves a more classical understanding of electrons that behave as particles, while the the other involves more "quantum mechanics' electrons behaving more like waves/particles duality.
