calcium
Calcium
One atom of (^{36}Cl) contains 20 neutrons. This can be calculated by subtracting the number of protons (which is 17 for chlorine) from the atomic mass number (36).
Calcium
Cl-35 isotope has 18 neutrons Cl-37 isotope has 20 neutrons
Potassium has 19 protons, 19 electrons and 20 neutrons.
Calcium is the answer. Atomic weight 40 - with 20 protons means 20 neutrons. Calcium is a key element in teeth and bones.
Calcium has 20 neutrons and is found in your teeth.
You are calcium. Most calcium atoms have 20 neutrons though 20 - 28 is possible, but it is the fact that they have 20 protons which makes them calcium.
