Answer is in the question itself. 19. Because atomic mass is nearly equal to the mass number of the atom. Mass number is always a round number that is natural number. The proton code for fluorine atom is 9. Mass number is the total number of protons and neutrons. So for mass number 19, the number of neutrons will be 19 - 9 = 10.

The atomic number by definition is the number of protons in the nucleus, therefore 19 in this instance. (The isotope effectively specified by the numbers given in the question is potassium-40, which is least commonly occurring natural isotope of potassium.)

the answer is like numbers that come in a row like 7 or 8 and 19 and 20.

The atomic number for potassium is 19, which means it has 19 protons in its nucleus. The mass number of potassium is approximately 39, which includes the sum of protons and neutrons in its nucleus.
