Answer 7

#5: Electron A emits mainly violet light when excited. Electron B emits primarily yellow light when excited. What can be said about the transition between energy electrons A and B?

A. The distance between the energy levels for Atom A is greater than for Atom B.

B. The distance between the energy levels for Atom A is less than for Atom B.

C. The number of energy levels jumped by electrons is more for Atom A than for Atom B.

Answer 8

#6: According to Einstein, why does the photoelectric effect occur?
A. The photoelectric effect changes with the emission of an atomic spectrum.
B. The photoelectric effect is related to the number of electrons in the shells around a nucleus.
C. The photoelectric effect is due to the release of electrons from atoms.
D. The photoelectric effect has to do with the number of atoms in a material.

***im not too sure about this one but i would guess C.... idk is that right??? @aaronq ??

Answer 9

5 and 6 are right, but #4 I'm not sure, because you can't calculate the energy released or absorbed from the excitation or relaxation of electrons with E=hv

Answer 10

nvm oh okay, thanks!! :)

Answer 11

hmm well B sounds right but you'd have to know the wavelength

Answer 12

yeah its oaky, ill ask my teacher :P but i think its B :D

Answer 13

to calculate the energy released from an electron from a specific orbital you'd have to use this

Answer 14

oh oaky, thanks!! :)

Answer 15

so i think #4 is A haha

Answer 16

oh okay, thanks!! :P

Answer 17

#4 Is actually b (the energy released as an electron moves to a lower orbital) for those of you who are wondering.
