Hi, Can someone please explain this to me? "The axis of rotation for a non-quantum-mechanical object can point any way it likes. The Earth could rotate around an axis ninety degrees from the current one, so that the North Pole always faces the sun and the South Pole always faces away from it...

Well, there are no values given in the question. I'm just a beginner in quantum mechanics and am not good at graph plotting but I'll try with your guidance:) The graph is between radius;the distance of orbital from the nucleus and 4πr2 (psi)2, I think the probability density? Now how to plot...

In quantum mechanics, my textbook has this question: "Draw the distribution curves for radial wave function of 1s,2s,3s orbitals." Distribution curve is "The probability density of finding an electron in polar coordinates."

Hi, can anyone please guide me how to draw the distribution curves for radial wave function of an orbital? Please explain stepwise and in easy way. Thanks.

"The peaks represent the maxima of the probability density function." So, as the increase in l, means increase in zero probability region thus the number of peaks decrease, am I right? And in case of n, the energy is nothing to do with probability density but with the electron's distance from...

I realized now, from the Ist image the average radius of n= 3 agrees with Bohr's radius of n=1 that's 53 pm I think. But I don't understand why? And what does these peaks represent? Also when we say electron in 2s has lower energy than 2p, because of screening effect,I couldn't understand what...

The peaks of probability wave are the points where the electron is mostly likely to be found, and these peaks form the electronic cloud boundary with a radius in agreement to that predicted by Bohr's model. And each cloud has a specific wave pattern represented by specific number of peaks, the...

I was referring to this point on the site: "Each wave pattern is identified by an integer number n, which in the case of the atom is known as the principal quantum number. The value of n tells how many peaks of amplitude (antinodes) exist in that particular standing wave pattern; the more...

Hi, Just wanted to ask, the principal quantum number represent the number of peaks of the probability wave and I think more the value of n, more the energy of the electron as the wave has more peaks so higher frequency,am I right? Then in azimuthal quantum number, the orbitals with same energy...

Thank you very much for your reply. Then, how much detail I can include in an answer, when I've four questions to attempt along with diagrams and the time limit is three hours?

Hi, In exam, answering the question,"compare/differentiate between prokaryote and eukaryote cell." Should I write this in columns, writing the differences and comparing them? Or in paragraphs? Which is the right method? And can I include the significance about their differences? I mean, like...

Hi, everyone. I just wanted your advice as at bachelors level, how much material you need to study for a topic? For example, if you're asked to describethe valance bond theory applications in chemistry, should I study and write the points of VBT and give 4-5 applications and explain the theory...

But how this explain that the reaction rate can be found by just looking at the rate of any specie involved in the reaction? And if just one reactant is enough to determine the rate of the reaction, then why we use the product of concentration of reactants in rate equation?

Is it based on: Rate of consumption of A = Rate of consumption of B and are equal to rate of production of C= rate of production of D? Then the reaction rate of B will also be 1mol/sec? Confused!

Can you give me an example? How just one reactant concentration change is enough to calculate reaction rate? If you have two reactants forming two or more products?
