The standard atomic notation for potassium is K-39. This indicates that the element has a mass number of 39.
The standard atomic notation for boron is ^10B.
The standard atomic notation for an atom of argon with 20 neutrons and 18 protons is 38Ar.
The standard atomic notation for the sodium-23 atom is: Atomic number (number of protons) = 11 Mass number (sum of protons and neutrons) = 23 Symbol = Na Putting it all together: ^23Na
The atomic notation of boron is ( ^{5}_{B} )
Only elements have a particular (unique) atomic number. Potassium (K) has 19 and chlorine (Cl) has 17 as atomic number (= proton number)

The standard atomic notation for an atom of argon with 20 neutrons and 18 protons is 38Ar.
In the periodic table, "K" represents potassium, which has the atomic number 19. The "O" in "KO" typically refers to oxygen, with the atomic number 8. However, "KO" is not a standard notation in the periodic table; it might refer to potassium oxide (K₂O) in chemical contexts, where potassium combines with oxygen.
