chapter 2 Q29

Postby Rachel Brown 3A » Tue Oct 24, 2017 11:47 am

can someone help me with parts B and D on question 29? Question reads: how many electrons can have the following quantum numbers in an atom...

B) I don't understand how when n=4 and l=2, only two electrons can have these quantum numbers.

Same thing for D when n=3, l=2, and m=1...

For (b), it says n=4, l=2, and ml=-2. It shows a specific orbital in 4d-orbital. According to Pauli exclusion principle, no more than 2 electron can occupy any given orbital. So, only two electrons can have these three quantum number. The same thing for (d). Only two electrons can occupy a 3d-orbital.
