The atomic number is 19 and the mass number of its most abundant isotope K-39 is 39 (19 protons + 20 neutrons) while the mass of that isotope is 38.96371 a.m.u.
The relative Atomic Mass of the element potassium, K, is 39.10 g/mole.
Atomic number is 19, atomic mass is 39.
Potassium is a metal element. Atomic mass of it is 30.
The atomic number is the number of protons: 19.number of neutrons = mass number - atomic number = 21.The number of electrons is normally the same as the number of protons: 19
The answer is Fluorine!Argon, one of the noble gases.
The atomic number of potassium is 19. This means that there are 19 protons in every potassium atom, regardless of isotope.
Number of neutrons = Mass number - atomic number
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
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.
Fluorine is a non metal element. Atomic mass number of it is 19.
The atomic mass of potassium is 39.0893
K, or potassium, has a mass number of 19. Fluorine is a non metal element. Mass number of it is 19. No, mass number for potassium is not 19. That is the atomic number.
Potassium
Potassium is a metal element. Atomic mass of it is 30.
Potassium is a metal element. Atomic mass of it is 30.
The atomic number of the potassium is 19. So the number of protons and electrons is 19 in the atom of potassium. The number of neutrons can be calculated as mass number minus atomic number. It comes to be 39 minus 19. That is 20.
the relative atomic mass for the element potassium is 39.0983
the atomic mass of potassium is approximately 39
