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