Homework Answers
1.There are 7 atomic orbitals in the f-subshell.
2. For n=3, the values of l range from 0 to (n-1). Hence the maximum value of l allowed for n=3 is 2.
3. for n=6, the maximum no of electron in this shell is given by 2n2, maximum no of electron having n=6 are 72.
Rest of the questions aren't visible. Please post them again.
4. There are 10 d-electrons in a ground state K atom.
5. The electronic configuration of Al is 1s22s22p63s23p1. The principle quantum number for valence electrons in Al is n=3.
