Questions
A Sulphur atom in its ground state has the electronic configuration How many orbitals are occupied by at least one electron?
detailed solution
Correct option is D
The electronic configuration of Sulphur atom is . The s subshell has one orbital which contain maximum 2 electrons . The p subshell has 3 orbitals which contain maximum 6 electrons. So, Total orbital occupied by at least one electron is 1+1+3+1+3 = 9 orbitals ( since,1s= 1; 2s=1; 2p=3; 3s=1; 3p=3).
