A magnesium atom typically has 12 neutrons. Magnesium has an atomic number of 12, indicating it has 12 protons which is equal to its number of electrons in a neutral atom. The number of neutrons can be calculated by subtracting the atomic number from the atomic mass of magnesium, which is approximately 24.305 amu.
Sodium does have an atomic number of 11, and if the isotope's atomic mass is 23, the atom would have 11 protons (the atomic number) and 12 neutrons (the atomic mass minus the atomic number). The atom would have 11 electrons, and when ionized it would lose one and take on a charge of +1.
To find the atomic number of an element, you need to subtract the number of neutrons from the isotope's mass number. In this case, if the isotope has 12 neutrons, the atomic number would need to be determined in conjunction with the mass number.
Mg has 12 protons since it is element number 12 on the periodic table. To calculate the number of neutrons, subtract the atomic number (12 protons) from the atomic mass (26), which gives 14 neutrons in this case.
Subtract the atomic number from the mass number. Example Carbon-12 an isotope with a mas number of 12. Carbon has an atomic number of 6 therefore carbon-12 has 6 neutrons.
To find the number of neutrons in an atom with an atomic number of 12 (which is the number of protons), you would subtract the atomic number from the atomic mass number. The atomic mass number is the sum of the protons and neutrons in the atom. For an atom with an atomic number of 12, the number of neutrons can be calculated by subtracting 12 from the atomic mass number given for that specific atom.
A magnesium atom typically has 12 neutrons. Magnesium has an atomic number of 12, indicating it has 12 protons which is equal to its number of electrons in a neutral atom. The number of neutrons can be calculated by subtracting the atomic number from the atomic mass of magnesium, which is approximately 24.305 amu.
Number of neutrons = Mass number - Atomic number = 22 - 12 = 10
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 number) - 12 (atomic number) = 12 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.
Sodium does have an atomic number of 11, and if the isotope's atomic mass is 23, the atom would have 11 protons (the atomic number) and 12 neutrons (the atomic mass minus the atomic number). The atom would have 11 electrons, and when ionized it would lose one and take on a charge of +1.

The atomic mass number of an atom is the sum of its protons and neutrons. Sodium typically has 11 protons, so if the atom has 12 neutrons, the atomic mass number would be 23 (11 protons + 12 neutrons).
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.
Neutrons in an atom Equation Atomic Weight - Atomic Number = The neutrons of an element Round for the final answer Example: Sodium (Na) Atomic Number: 11 Atomic Weight: 23 23-11= 12 neutrons so therefore sodium has 12 neutrons
Subtract the atomic number from the mass number. Example Carbon-12 an isotope with a mas number of 12. Carbon has an atomic number of 6 therefore carbon-12 has 6 neutrons.
