Differences (Bohr Model)
Name one property of the Bohr Model! (having to do with path)
Electrons have a set and circular path they travel around the nucleus.
Name one property of the QM Model! (having to do with path)
Uncertainty principle is incorporated! It is impossible to know exact the location and momentum of an electron, only clouds of probability of where they are likely to be.
Name one similarity between the Bohr and QM Model! (having to do w/ existence between orbitals)
They both establish that electrons can't exist b/w orbitals. They travel from one orbital or energy level to the next whenever they gain/lose energy.
How are interactions between electrons & energy represented in the Bohr model?
As electrons gain energy, they enter an excited state and jump up from their ground state to a higher energy level/shells. But once they lose and release that energy, they jump back down, and based off their wavelength and how low they jump, they emit different colored lights.
How are interactions between the nucleus and the electrons represented in the Bohr model?
The electrons circle the nucleus in orbitals, staying together because of the force of attraction holding them together!
Name another property of the Bohr Model! (has to do with e-'s behavior)
Describes electrons as having particle-like behavior.
Name another property of the QM Model! (has to do with e-'s behavior)
It treats electrons not just as particles but more as waves (like light waves) which can gain and lose energy.
Name another similarity between the Bohr and QM Model! (having to do w/ number of electrons per level)
They both have a limited number of electrons per level.
How are interactions between electrons & energy represented in the QM Model?
As they gain energy, they first occupy the s-orbital, then p-orbitals and so on. Only after they fill all the orbitals on that original energy level will they move on to the next level.
How are interactions between the nucleus and the electrons represented in the QM model?
The electrons travel in wave-like patterns in clouds of possibility surrounding the nucleus, with no way of knowing where they must be at a certain time.
Name one last property of a Bohr Model! (having to do with what it works for)
It only works for atoms with one electron (hydrogen).
Name one last property of the QM Model! (having to do with what it works for)
It works well for explaining the behavior of the atoms (especially e-'s) of all elements
Name another similarity between the Bohr and QM Model! (having to do w/ order of filling orbitals)
Only when the previous orbitals/shell is full, are electrons allowed to begin filling the next level.
How is the interaction b/w electrons and energy shown in the flame test experiment?
In our flame test experiment, we saw how when different elements get heated up they emit different colored lights. This is the process of electrons gaining the heat energy from the Bunsen burner and jumping to higher energy levels. Then as they tire out, they jump back down and release light, and their colors vary based on the element and its unique specter.
A light bulb was held to a plasma ball and the only part of the light bulb that lit up was the part between where the hand held it and the part touching the plasma ball. The light bulb lit up because it created a path of less resistance than the surrounding gases and glass. Only the part between where the hand held it and the part touching the plasma ball lit up because the hand created another pass of less resistance, so the electricity went through the person instead of the rest of the light bulb. This connects to the QM Model's idea of never fully knowing the position or velocity of a particle at the same time since electrons are still moving. It also connects to the QM Model's idea of treating the electrons' movement as a wave-particle duality, as electrons move through other things, versus the Bohr Model's idea of treating the electrons as only particles.
