Potassium ( K ) has an atomic number of 19 which is located in group 1, period 4 of the periodic table. The electronic configuration is K:1s22s22p63s23p64s1
The 2p and 3p sublevels each hold six electrons, which means that they are completely occupied. Since every p sublevel has a total of three p-orbitals – px, py, and pz. Therefore 3 p-orbitals on the 2p sublevel and 3 p-orbitals on the 3p sublevel is occupied by the electrons which means K has total of 6 p-orbitals which hold 12 of its 19 electrons.
