Question

Does each orbital have exactly the same amount of energy?

Answer 1

@matt101 I believe the answer is yes because each orbital has 2 electrons.
Am I correct?

Answer 2

I see where you're coming from, but the answer is no.

Remember, orbitals can be part of any energy sublevel (which themselves have different energies), and you can have different sublevels in any energy level (which for sure have different energies).

This goes back to your question about energy levels being quantized.

Answer 3

@matt101
The angular quantum number describes the shape or type of an orbital.
In a video it says
s=0 p=1 d=2 f=3 What do these indicate?

Answer 4

@dtan5457 do you know about it?

Answer 5

The angular momentum quantum number is another word for azimuthal quantum number. Remember, this quantum number describes the energy sublevel we're talking about. The quantum number can be any whole number greater than or equal to 0, and these numbers correspond to the sublevels s, p, d, f, etc as you wrote above.

Answer 6

but why s=0 ?

Answer 7

It's just the convention.

If the angular momentum quantum number is 0, we're talking about an s sublevel.
If the angular momentum quantum number is 1, we're talking about a p sublevel.
And so on...

Answer 8

Ok I got it. How did you learn all this stuff? Especially with memorizing it?

Answer 9

I've taught it to myself several times over the years during high school and university. I've taught it to others many more times. I find that if you're able to explain something to someone else so that they understand it, it improves your own understanding of whatever you're explaining.

It's gotten to the point where it's not so much that I've memorized everything but rather I see how it all fits together in the big picture, so usually I can fill in the blanks even if it's something I haven't encountered in a while.

Answer 10

Wow that is amazing. Keep up your good work. I wish we could return all this favor and help you give us. Thanks man :D

Answer 11

Hey not a problem! Glad I'm able to help people out!

Answer 12

Are you a professor?

Answer 13

Nope

Answer 14

You see like a professor to me? What do you for a living?

Answer 15

Haha definitely not a professor. I'm a graduate student.

Answer 16

I am sure you will make it doctor degree and even higher. I have rarely seen someone with this much information. I have to go, but keep yourself ready for tomorrow. I got some big questions for you ;) :D

Answer 17

Alright lol take care
