Re: 14B Next Quarter

I am not sure if it's confirmed that 14B is also asynchronous since on MyUcla it still says its online recorded. But, I am sure Lavelle will accept everyone off the waitlist again next quarter. It would be good to confirm with him just in case. Although it says "Online - Recorded" it coul...

Re: Test Anxiety

I've learned that more practice reduces my anxiety. Especially for this class, there are plenty of practice problems in the textbook, UA sessions, and Sapling. After understanding all those questions, I feel more prepared to take the exam.

During Dr. Lavelle's OH, he also mentioned that having negative energy is favorable since it has low energy.

Re: Mid-quarter Check in

It is going really fast! I feel like the quarter just started, but we are already planning our schedule for winter quarter. I hope I can keep myself motivated for the rest of the quarter, but it is really hard to do so with online classes. Wishing we were on campus!

Re: Valence Electrons

To find an element's valence electrons, I count the number of columns on the periodic table. But, remember to skip the transition metals. So for example, the element Boron is in the 3rd column, meaning it has three valence electrons. This also makes sense because Neon is in column 8 and having 8 val...

Re: Expanded Octet

During a step-up session, the UA told us to know P, S, and Cl as the exceptions to the Octet rule. There are definitely more elements that are exceptions, but for this class these three are the only ones we need to know.

Re: Speed of light

For most problems using 3.0 x 10^8 m/s resulted in the correct answer. But for exams, it would be safer to go with the more precise value given on the formula sheet.

Since the electron is returning to a lower energy level from n=5, the lowest it can drop to is n = 1. For each level it drops, there will be a spectral line that will appear. To find the wavelength range, you know that since the electron is returning to a lower energy level it can be anywhere from n...

During a step-up session, the UA told us a good way to remember the difference between the Lyman and Balmer series.
Lyman goes Lower (n=1) and Balmer has the letter B which is the 2nd letter of the alphabet so (n=2).

I used the equation Energy (photon) = Work + Kinetic Energy To find the maximum number of electors ejected, you would set the Kinetic Energy = 0. The energy of each photon is equal to the work function since the energy of work is given in J/Photon. Now you can calculate the number of photons equal t...

I agree with everyone else! I would use a scientific/graphing calculator for those problems. I would also add parentheses to the numerator and denominator just to be sure the calculator understands the function.

Re: Electron not emitted even for high intensity light

Hi! I was also a bit confused on that. I think increasing the intensity of the light would increase the number of photons present, but the each photon does not have enough energy to eject an electron. Increasing the number of photons does not allow them to add up all their energy. Each photon still ...
