Phosphorous-32

The nucleus of phosphorus-32 contains 15 protons and 17 neutrons, one more neutron than the most common isotope of phosphorus, phosphorus-31. The atomic number (also known as the proton number) is the number of protons found in the nucleus of an atom and therefore identical to the charge number of the nucleus.

Isotope mass: 31.973907274
Element Symbol: P



Hope you can tackle Barium now Wink Face
