Question

How many electrons in the same atom can share the quantum number n = 2?

A. 2 B.6 C.8 D.10

Answer 1

\(\huge2*n^2\)

just fill in

Answer 2

Would it be 8?

Answer 3

n=2 can have l=0 and l=1.
l=0 has 1 orbital and l=1 has 3 orbitals.
each of the orbital has 2 electrons

Answer 4

yup, \(\large2*n^2=2*4=8\)

Answer 5

Thank you

Answer 6

but this only works when n alone is given

Answer 7

when the angular quantum number (l) is given, it doesn't work anymore and you'll have to calculate it in another way

Answer 8

So if when the angular quantum number (l) is given, how would you calculate that?
