A Sulphur atom in its ground state has the electronic configuration 1s22s22p63s23p4 How many orbitals are occupied by at least one electron? - Sri Chaitanya Infinity Learn Best Online Courses for NCERT Solutions, CBSE, ICSE, JEE, NEET, Olympiad and Class 6 to 12

Solution:

The electronic configuration of Sulphur atom is $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{4}$ . 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).
