They are NOT normally arranged by atomic mass; instead they are arranged in the periodic table by their atomic number. The latter is the number of protons (or electrons) in a single atom of the element and it is a constant for the element. The atomic mass is an average of the isotopes of the element (in proportion to their abundance).While the atomic number is always an integer, increases in steps of 1 and elements that are a specific "distances" apart share similar chemical characteristic. On the other hand the atomic mass is rarely an integer, and occasionally it reverses the order laid out be the periodic table: for example, element 18, argon has an atomic mass of 39.948 which is greater than that of element 19, potassium with a mass of 39.098: this is because the predominant isotope of argon has 22 neutrons while that for potassium has 20 neutrons.
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.

The atomic number of potassium is 19.The atomic weight of potassium is 39,0983(1).The mass number of the isotope potassium-39 is 39.
The nearest Whole number of atomic mass of potassium is 69
potassium
Pottasium is a meta element. Atomic mass of it is 39.
Potassium is a non metal element. Atomic mass of it is 39.
Since potassium chloride has the formula KCl and the mass of the lost electron from neutral potassium is negligible compared with the mass of the protons and neutrons in the potassium atom nucleus, the molecular mass of potassium in this compound is the same as the atomic mass of potassium, 39.098.

Potassium
The atomic number of potassium is 19. The mass number is the number of protons plus the number of neutrons. The three natural isotopes of potassium have mass numbers of 39, 40, 41.
