Thus, electronic configuration of potassium is
               Number of orbit in potassium = 4





               Electronic configuration of Calcium (Ca)
               Atomic number of calcium = 20
               Therefore, number of electrons = 20


               Thus, electronic configuration of calcium is
               Number of orbit in calcium = 4
