That depends on which isotope you're after:
Natural occurring Phosphor has 16 neutrons next to its 15 protons in nucleus,
but also with 15, 17,and 18 neutrons are possible isotopes, though not stable and not naturally occurring.
Phosphorus has 16 neutrons.
there are 12 nuetrons in an atom of magnesium
protons and nuetrons are equal to no. of electrons present in atom
there are 12 protons in an atom of magnesium:-)
it has 35 nuetrons, 30 protons, and 30 electrons with a mass of 65
Neutrons: 6 Protons: 6 Electrons:6
A phosphorus atom typically contains 16 neutrons. This can be determined by subtracting the atomic number, which is 15 for phosphorus, from its atomic mass, which is usually around 31 for the most commonly occurring isotope.
In an anti-atom, there are anti-nuetrons.
In the nucleas
The nuetrons are found in the nucleus.
