Number of orbitals that could be associated with 'n' are;

a) n^2 + 2

b) 2n^2

c) n^2

d) n^2-2

Question

Number of orbitals that could be associated with 'n' are;




a) n^2 + 2

b) 2n^2

c) n^2

d) n^2-2

anonymous · Answer

The answer is b) 2n^2

If n = 1, then there only exists the S level, which contains 2 orbitals. so 2 * (1^2) = 2
If n = 2, there is the S level and P level, which contains 2 orbitals + 6 orbitals. so 2 * (2^2) = 8.

based on these relationships, 2n^2 shows how many orbitals there are according to the value of 'n'

orbitals refers to elektrons???

if not then korect ans is n^2

I am very sorry! My above post was incorrect. I was under the impression that we were talking about the number of electrons in each "n" level.  I wrote "orbitals" in the place of what should be "electrons."  mos1635 is correct.  The relationship between the number of orbitals and "n" is n^2

So the correct answer is C) n^2
