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
