Write the distribution of electrons in carbon and sodium atoms.

Q.:- Write the distribution of electrons in carbon and sodium atoms.

 

Answer:-

Atomic number of carbon = 6

Hence first shell (K – shell) have 2 electrons and the remaining 4 electrons will be present the second shell, i.e. L- shell. Thus the distribution will be
                                 K                              L
                                 2                              4
Atomic number of sodium =11. Hence, 1st shell (K-shell) will have 2 electrons and 2nd shell (L-shell) will have 8 electrons and 3rd shell (M-shell) will have 1 electron. Thus, the distribution will be
                         K                      L                    M
                         2                       8                    1
