Question

Which of the following orbitals does not exit? 6s,3p,2d,4f

Answer 1

Answer:

2d

Explanation:

since for an n value,upto n-1  orbitals are possible

that for n=2 the value of l are upto   2-1=1.....0 ,1  are possible that is  s and p are possible

Answer 2

2d orbital does not exists as 2 which is principal quantum number also denoted by (n)

can contain maximum 8 electron by using the formula 2n^2 i.e. (2*2^2)=8 . 2s orbital contains 2 electron and 2p orbital contains 6 electron which gives the sum 8. Thus, 2d orbital does not exist.
