13 neutrons. Atomic number of Mg is 12 equal to the number of protons.
So 25-12=13.
The atomic number of magnesium is 12. So there are 12 protons
The main difference between magnesium-24 and magnesium-25 is their atomic mass. Magnesium-24 has 24 protons and neutrons in its nucleus, while magnesium-25 has 25 protons and neutrons. This difference in atomic mass results in different physical and chemical properties between the two isotopes.
Any atom of magnesium will have 12 protons.Neutral atoms of Mg-24 will have 12 neutrons and 12 electrons. Mg-25 has 13 neutrons and Mg-26 has 14 neutrons. A magnesium ion will have either 10 or 11 electrons.
Sulfur-25 has a total of 25 nucleons, which include both protons and neutrons. Sulfur has an atomic number of 16, meaning it has 16 protons. To find the number of neutrons, subtract the number of protons from the total nucleons: 25 - 16 = 9. Therefore, sulfur-25 has 9 neutrons.
In it's most stable form, 55 is its atomic mass. 55 overall - 25 protons = 30 neutrons
25 is the number of protons and neutrons added together. The atomic number of Mg is 12 which is the number of protons. So 25 - 12 = 13 neutrons.
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.

13 neutrons
The number of protons (p+) in the nuclei of an element's atoms is the atomic number of the element. In this case, the atomic number of magnesium is 12. In a neutral atom, the number of electrons (e-) equals the number of protons. So all neutral magnesium atoms have 12 protons and 12 electrons. Isotopes of an element differ in the number of neutrons (n0).There are three stable isotopes of magnesium (Mg) identified by their mass numbers; magnesium-24, magnesium-25, and magnesium-26. The mass number is the sum of protons and neutrons in the nucleus of an atom. To determine the number of neutrons, subtract the atomic number from the mass number. (mass number - atomic number = no. of neutrons)Magnesium-24: 24 - 12 = 12; An atom of Mg-24 has 12 p+, 12 e-, and 12 n0.Magnesium-25: 25 - 12 = 13; An atom of Mg-25 has 12 p+, 12 e-, and 13 n0.Magnesium-26: 26 - 12 = 14; An atom of Mg-26 has 12 p+, 12 e-, and 14 n0.

The number of neutrons in the nucleus of an element can be calculated by subtracting the atomic number (which is the number of protons) from the atomic mass. For magnesium, the atomic number is 12, and the atomic mass is usually around 24-25. Therefore, the approximate number of neutrons in the nucleus of magnesium is 12-13.
