What atoms are in potassium?

Answer 1

Which potassium atom do you want? At what level do you want to count particles?

1. potassium-38: either 19 protons & 19 neutrons or else 114 quarks
2. potassium-39: either 19 protons & 20 neutrons or else 117 quarks
3. potassium-40: either 19 protons & 21 neutrons or else 120 quarks
4. potassium-41: either 19 protons & 22 neutrons or else 123 quarks
5. potassium-42: either 19 protons & 23 neutrons or else 126 quarks
6. potassium-43: either 19 protons & 24 neutrons or else 129 quarks
7. potassium-44: either 19 protons & 25 neutrons or else 132 quarks

I hope you did did not mean to count either the mesons or gluon that's convey the strong force in each case.

Answer 2

Protons, neutrons, and electrons make up the element potassium. Specifically, there are 19 protons and 19 electrons in each potassium atom. If the element's stable, then an atom can have either 20 or 22 neutrons.

Answer 3

Potassium is an element, so it is composed of potassium atoms.

Answer 4

Potassium has 19 electrons and protons; the number of neutrons is specific for each isotope.

Number of neutrons in a potassium atom = Mass number - 19

Answer 5

Potassium has 19 electrons and protons; the number of neutrons is specific for each isotope.

Number of neutrons in a potassium isotope = Mass number - 19
