How many neutrons are in a atom of magnesium?
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.
What is atomic number of 12 neutron?
12 neutrons has nothing to do with atomic number. Atomic number is the number of protons. You might mean sodium. Sodium has an atomic number of 11, and an atomic mass that rounds to 23, so 23 -11 = 12 neutrons in some isotopes of sodium. but some atoms of magnesium atomic number 12 also have 12 neutrons with a mass number of 24, and probably some other element, but those are all I can think of now.
Why the magnesium have a atomic mass of 24?
Magnesium has 12 protons and 12 neutrons in its nucleus. The atomic mass is the number of protons and the number on neutrons added together, so 12 + 12 + 24.
How do you find the number of neutrons in an isotope?
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.
Sodium has an atomic mass of 23 and an atomic number of 11 so the number of neutrons must be?
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.
What is the number of neutrons in an atom with atomic number 12 and mass number 22?
Number of neutrons = Mass number - Atomic number = 22 - 12 = 10

How many neutrons are present in a magnesium atom with a mass number of 24?
12 neutrons. Since the atomic number of Mg is 12 (which means Mg atom has 12 protons, and 12 electrons) and the mass number of the isotope is 24 (which means 24 nucleons, or 24 protons and neutrons in total), we derive the number of neutrons by 24 - 12 = 12.
How do you the get neutrons?
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

How do you find the number of neutrons in an isotope?
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.
If an Atom has an atomic number of 12 What is the atomic number?
Atomic number depends on the number of protons and it doesn't matter how many neutrons there are in that case. Neutrons only contribute to the atomic weight. The atomic number is the same as any other atom of carbon: 6.
Sodium has an atomic mass of 23 and an atomic number of 11 so the number of neutrons must be?
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.
How do you determine the number of neutrons for a sodium atom?
Subtract the proton number or atomic number (11) from the nucleon number or the atomic mass (23) and you get the number of neutrons = '''12'''.
If the atom has 14 protons and 12 neutrons what the atomic number?
The atomic number is 14 - silicon.
