Potassium 31 is potassium's normal state, the way you would find it on the Periodic Table. I presume potassium 41 is an isotope of potassium. (An isotope is the same atom, but it has a different number of neutrons, so the mass differs.)

What is the atomic number and mass number for 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.
How are potassium 40 and calcium 40 alike?
They have different numbers of neutrons. All potassium atoms contain 19 protons. Potassium-39 has 20 neutrons while potassium-40 has 21. The extra neutron adds about 1 AMU to the mass of the atom.
What is 39 in potassium?
39 is the atomic mass of one atom of potassium. This is essentially the weight of one atom
How does potassium-19 differ from potassium-41?
The nomenclature "potassium-19" is not commonly used because it is redundant. The 19 in potassium-19 would indicate the number of protons in potassium. All isotopes of potassium have 19 protons. Therefore 19 is known as the atomic number of potassium. Potassium-41 is one of the three naturally occurring isotopes of potassium. It has 19 protons and 22 neutrons, giving it an atomic mass number of 41.
How many atoms are there in 39 g of potassium?
The atomic mass of potassium is 39 ,therefore the number of mole is 39 /39,which is 1then multiple by Avogadro number you get 6.022*10^24
The atomic number of potassium is 19 how does potassium -39 differ from potassium -41?
39K has 20 neutrons and 41K has 22 neutrons.
What is the atomic number and mass number for 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.
How much mass is in potassium?
Every atom of potassium has a mass of 39 amu. Each mole of potassium has a mass of 39 grams.
What is 39 in potassium?
39 is the atomic mass of one atom of potassium. This is essentially the weight of one atom
How are potassium 40 and calcium 40 alike?

What is the mass number of potasium?
Potassium occurs naturally on earth in three isotopes with mass numbers 39, 40, and 41. Of these, the isotope K-40 is known to be radioactive, but has a very long half life. There are many other radioactive isotopes of potassium.
Which is a prime number 41 or 39?
41 is the prime number.
The atomic weight of potassium is 39.1 From this one could correctly conclude that?
... that there's at least one natural isotope heavier than K-39: Indeed there is K-41 (about 7%)
How many neutrons occur in potassium with a mass number of 39?
Potassium is element number 19 and so 39-19 = 20 neutrons
