Atomic Mass is the number of protons added to number of neutrons.
Number of protons is element's atomic number, and you can count neutrons by subtracting atomic number from atomic mass.
So, it can be any substance which has a atomic number 12 lower than atomic mass.
Basically, i would say that it is Magnesium 24 isotope [most common Magnesium isotope], because it has 12 protons and 12 neutrons [12 + 12 = 24]
Sodium 23 isotope [also most common] fits perfectly too.
However, it can be any other material's isotope. For example Aluminum 25 [13+12=25] Neon 22 [10+12=22]
Sodium is a metal element. Mass number of it is 23.
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 number).
none because the number of protons and electrons have to be the same.
The element that has 8 protons and 8 neutrons is oxygen.
carbon or boron
Any atom, ion, or isotope with 12 protons is going to be magnesium. Only the number of protons in the nucleus will determine the element. But with the information about the number of neutrons, the specific isotope can also be determined - 22Mg.
Yes. An example would be carbon-12. It has 6 protons and 6 neutrons.
Carbon-12 has 6 protons, 6 neutrons, and 6 electrons. The number of protons determines the element (carbon), the number of neutrons plus protons gives the mass number (12), and in a neutral atom, the number of electrons equals the number of protons.
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.
12. the atomic number of an element is the number of protons in it's nucleus. The mass number is the number of protons+neutrons. Therefore the element has (32-20)12 protons.
Sodium is a metal element. Mass number of it is 23.

You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.
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 number).

The element that has 8 protons and 8 neutrons is oxygen.
