How many neutrons occur in potassium with a mass number of 39?
Potassium is element number 19 and so 39-19 = 20 neutrons
How many neutrons are found in one atom of 40K?
I'm assuming you are referring to Potassium (K)-40. All Potassium has 19 protons, though there are many stable isotopes. Potassium-40 has 21 neutrons.
How many protons and nutrons does potassium have?
Potassium have th atomic number of 19 this means it has 19 protons in its "core" and in atoms the number of electrons are always equal to the number of protons hence also 19. the number of neutrons however vary dependent on witch potassium isotope it is the average for potassium is however 20 in potassium 39
How many protons does potassium 39 have?
The mass number, the number that follows the hyphen at the end of an element name, is the sum of the atomic number of the element and the number of neutrons in each atom of the isotope specified by mass number. The atomic number of potassium is 19; therefore, potassium-39 contains (39 - 19) or 20 neutrons.
How many electrons and neutrons are in potassium?
Potassium (K) Has the same number of electrons as protons therefore it has 19 electrons. To find the number of neutrons you take the mass of the element minus the number of protons so 39-19=20. so there are 20 neutrons in potassium.
How you calculate the number of neutrons in potassium-40?
By subtracting 19 (atomic number of Potassium) from 40. You should come out with 21, which is the number of neutrons in potassium-40
How many neutrons in potassium 41?
the answer is 21. because you do 40-19
How do you get the answer for the number of neutrons for potassium?
by thinking
How many neutrons occur in potassium with a mass number of 39?
Potassium is element number 19 and so 39-19 = 20 neutrons
How many electrons does a neutral atom of potassuim contain?
The number of neutrons in any element depends on the isotope of the element you are referring to. Potassium has 24 isotopes, ranging from 32K to 55K. The most stable natural isotope is 39K, which would have 20 neutrons.
How many neutrons are found in one atom of 40K?
I'm assuming you are referring to Potassium (K)-40. All Potassium has 19 protons, though there are many stable isotopes. Potassium-40 has 21 neutrons.
The atomic number of potassium is 19 how does potassium -39 differ from potassium -41?
39K has 20 neutrons and 41K has 22 neutrons.
How many protons electrons and neutrons does 31potassium have?
From the periodic table, potassium has an atomic number of 19. This means that potassium atoms have 19 protons in their nuclei. In a neutral atom, the number of protons equals the number of electrons. Therefore, potassium atoms have 19 electrons. Mass number is the sum of protons and neutrons in the nucleus of an isotope. If you know the mass number and number of protons, subtract the number of protons from the mass number. In the case of potassium-31, the mass number is 31. So, subtract 19 from 31 and you get 12, which is the number of neutrons. So the atoms of potassium-31 has 19 protons, 19 neutrons, and 12 neutrons.
How many protons and neutrons are in potassium?
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".

What is the atomic mass and neutrons are K?
The mass number of Potassium is 39 which means it has 20 neutrons.
How many neutrons does potassium-39 have?
Answer: 20 Details: mass number - atomic number = number of neutrons.
