How many electrons does a neutral atom of potassuim contain?

Answer 1

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.

Answer 2

Every element (when neutrally charged) has the same number of electrons as it's atomic number. In the case of potassium, it has 19 electrons. If you look at a Periodic Table, the symbol for potassium is K.

Answer 3

The most abundant potassium isotope, potassium-39, has 20 neutrons. Potassium-41, with a natural abundance of 6.73%, has 22 neutrons.

Answer 5

There are 20 neutrons in a potassium-40 atom

Answer 6

Number of Neutrons = Mass Number - Atomic Number

For the most abundant isotope of potasium, 39K: 39-19=20 neutrons

Answer 7

The number of neutrons is different for each isotope of an element.

For potassium isotopes: Atomic Mass of the isotope - 19 = number of neutrons

Answer 8

The most stable atom of potassium has 19 electrons and 20 neutrons.
