The number of neutrons is entirely dependent on the Mass number of the particular atom. The standard mass for potassium is 39.
Potassium is element number 19, so it has 19 protons and 19 electrons in the neutral atom. It has therefore 39-19 = 20 Neutrons.
There are 18, 20 or 22 neutrons.
Hydrogen typically has 0 neutrons.
In-115 isotope has 66 neutrons
the average amount of neutrons in chlorine is 18, but there could be more or less with the different isotopes
Number of neutrons is 48 (mass number) minus 21 (proton number) = 27 (neutron number)
Potassium (K) typically has 19 neutrons in its nucleus. Potassium-40 is a radioactive isotope with 21 neutrons in its nucleus.
Potassium has 19 protons, 19 electrons and 20 neutrons.
Potassium typically has 20 neutrons in its nucleus.
An atom of potassium has 19 protons, 19 electrons, and typically 20 neutrons.
the answer is 21. because you do 40-19
There are 19 protons,20 neutrons, and 19 electrons.
Potassium-41 contains 22 neutrons and 19 protons.
20 for the stable atom
Potassium has 20 neutrons in its most abundant isotope, potassium-39.
Potassium with a mass number of 39 has 20 neutrons. The mass number of an element is the sum of its protons and neutrons. Since the atomic number of potassium is 19 (number of protons), the number of neutrons can be calculated by subtracting the atomic number from the mass number.
19 protons 19 electrons 20 neutrons
Potassium has the atomic number 19; that means it has 19 protons. The number of neutrons - as with any element - depends on the specific isotope. For more details, check the Wikipedia article on "Isotopes of potassium".
