Question

How many Neutrons are there in Potassium

Answer 1

Each isotope has 19 protons and 19 electrons, but the number of neutrons vary.Potassium-39 has 20 neutrons, Potassium-40 has 21 neutrons and Potassium-41 has 22 neutrons. Therefore, each isotope of an element will have a different mass number but the same atomic number.

Answer 2

There are 20 neutron in potassium (K)
