A few quick questions
 

Hey everyone,
First time posting here, I have a few questions for General Chemisty:
1. What is the probability that an electron will be found within an atomic orbital?
2. How many many energy sublevels are contained in each of the hydrogens atom's first three energy levels?
3. Which if the following atomic orbitial designations are incorrect:
a. 7f b.3f. c.2d d.6p
Any help is appreciated,
Thanks,
Lou

Answer to number 2.
I think there is 6.
1s in the first energy level.
2s, 2p in the second energy level
3s, 3p, 3d in the third energy level.

Answer to number 3.
a.) correct
b.) incorrect, the f sublevel starts in the fourth energy level.
c.) incorrect, the d sublevel starts in the third energy level.
d.) correct

I hope I helped some, I'm not sure what you're asking for on the second question. The hydrogen's electron only is in the 1s sublevel anyway so I don't know why you need to know about the first three energy levels.
