Question:

Write the distribution of electrons in carbon and sodium atoms.

Answer:

The distribution of electrons in Carbon and Sodium atom :
Carbon :          Atomic no. of Carbon = 6
                         no. of protons = 6
                     no. of protons = no. of electrons
                     Distritribution of electron = K L
                                                                2  4
Sodium : 
        Atomic no. of Sodium = 11
                          no. of protons = 11
                       no. of protons = no. of electrons
                      Distritribution of electron = K L M
                                                                 2 8 1
