12 neutrons
Magnesium (Mg), number 12 on the periodic table, has 12 neutrons.
There are 11 protons and 12 neutrons. And that does not depend on the periodic table. Sodium had 11 protons and 12 neutrons long before the periodic table, or even human, beings existed!
Each element on the periodic table has a specific number of neutrons and will vary for its isotope.

The "25" is the mass number, which is the sum of the number of neutrons and protons. We don't know how many neutrons there are, but we do know how many protons magnesium has. The atomic number of an element is the same as the number of protons, so locating a Periodic Table, magnesium is number 12, which means 12 protons. If mass number = number of protons + number of neutrons, then number of neutrons = mass number - number of protons (or atomic number). So 25 - 12 = 13 neutrons in 25Mg.
The 12th element of the periodic table is magnesium. Magnesium has the atomic number 12 and is a silvery-white alkaline earth metal. It is essential for many biological processes and is commonly found in green leafy vegetables, nuts, and seeds.
Mg on the periodic table stands for magnesium. Magnesium is a metallic element commonly found in many minerals and in seawater. It is an essential nutrient for human health and is involved in various biological processes in the body.
Neutrons are sub-atomic particles. The Periodic Table is an arrangement of the elements (atoms) made from these subatomic particles. Thus Neutrons by themselves have no place in the Periodic Table. However as all elements/atoms (except Hydrogen) contain some Neutrons, it is possible to find out how many using the information presented on the Periodic Table. The number of Neutrons present in an element/atom can be determined by subtracting the atomic number of an element/atom from its atomic mass.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
It has two, since it is in the second column on the periodic table.
No. Atoms on the Periodic Table are listed by element in order of atomic number, which is the number of protons an atom contains. The number of neutrons in the atoms of an element usually varies among several isotopes.
