### Electronic configuration of Potassium (K)

Atomic number of potassium = 19

Therefore number of electrons = 19

Since, maximum number of electrons in outermost orbit will not be more than 8, thus the 19th electron of potassium atom will reside in 4th.

Thus, electronic configuration of potassium is

given in first pic.

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 given in sec pic.

Number of orbit in calcium = 4
