In an atom the number of electrons in M - shell is equal to the number of electrons in the K and L - shell . Answer the question. Explanation : 1) Number of electrons in K-shell (1 s^(2)) = 2 Number of electrons in L-shell (2s^(2) sp^(6)) = 8 Total number of electrons in k & L shells = 10 2) Given that number of electrons in M-shell is equal to number of electrons in K& L- shells 3) Hence number of electrons in M-shell (3s^(2) 3p^(6) 3d^(2)) = 10 4) But , we know that before filling of 3d orbital 4s should be filled (4s^(2)) 5) So , electronic configuration is 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 4s^(2) 3d^(2) What is the atomic number of element ?
