Natural isotopes of magnesium have 12, 13 and 14 neutrons.
Number of neutrons = Atomic weight - Atomic number (number of prtons) The atomic number of magnesium is 12; the standard atomic weight is circa 24,3. But magnesium has many isotopes (three are natural) and the number of neutrons is variable in the isotopes - from 7 to 28. The most common natural isotope, 24Mg, has 12 neutrons.
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
12 neutrons
13 neutrons
I believe it is two isotopes of an element. Because an isotope is the amount of protons. with a different number of neutrons in the nucleus. hopefully this will help :)
All neutrons have a negative charge. That is the reason they are called neutrons.
In an atom protons and neutrons are located in the atomic nucleus.
Neutrons.
Magnesium, the 12th element
the best answer is 12
12 and 12
neutrons
