The mass number is the sum of protons and neutrons in an atom. Since magnesium has 12 protons, a magnesium atom with 14 neutrons would have a mass number of 26 (12 protons + 14 neutrons = 26 mass ...
However, the number of neutrons will vary depending on the isotope (atoms of the same element with different numbers of neutrons). There are three isotopes of Magnesium, 24Mg, 25Mg, 26Mg, having ...
Magnesium, an element with 12 protons, does not have a fixed number of neutrons. It exists as many isotopes (differing versions of the same element with the same number of protons, but a different ...
Updated: 5/31/2024. Wiki User. ∙ 11y ago. Best Answer. A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one. Wiki User. ∙ 11y ago. More answers.
So 25 - 12 = 13 neutrons. Magnesium 25 has 13 protons in its nucleus, since its atomic number is 12. To get the number of neutrons, you subtract the atomic number from the Atomic Mass. So ...
13 neutrons. Atomic number of Mg is 12 equal to the number of protons. So 25-12=13. how many neutrons in magnesium? The "25" is the mass number, which is the sum of the number of neutrons and protons.
Since Magnesium-26 has an Atomic Mass of 26, it has 26 - 12 = 14 neutrons. To find the number of protons given this information, take the number of neutrons away from the atomic mass. 24-12 = 12 ...
A magnesium atom with a mass number of 24 has 12 protons because the atomic number of magnesium is 12. To find the number of neutrons, you subtract the atomic number from the mass number: 24 (mass ...
The mass number is the sum of protons and neutrons in an atom. Since magnesium has 12 protons, a magnesium atom with 14 neutrons would have a mass number of 26 (12 protons + 14 neutrons = 26 mass ...
The mass number of an atom is the sum of its protons and neutrons. Therefore, the mass number of a magnesium atom with 12 protons and 12 neutrons is 24. Mg has 12 protons. So the mass of Mg-24 ...
