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.
I believe that element is Magnesium with a charge of +2.
what has 10 neutrons in the nuclei
Yes. An example would be carbon-12. It has 6 protons and 6 neutrons.
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.
Neutrons-12 Protons -12 Electrons-10
Neon has the atomic number 10 which means it has 10 protons, it cannot have 12. Different isotopes of an element have the same number of protons but a different number of neutrons. There are three stable isotopes of neon.
This would be a Sodium-12 in ionic for or Na+
Magnesium2+ because it donated 2 electrons
(Explanation): remember that if an atom has less than 20 protons, the closer the number of neutrons and protons are, the more stable it is. Since 10 is closest to 12 out of these options, D is the correct answer.

it is the most stable isotope of sodium Na.
10 protons, 12 neutrons
Neutrons-12 Protons -12 Electrons-10

- The atomic symbol is only an abridged form of the name of a chemical element. - The chemical symbol of neon is Ne; the atomic number is 10. - The atomic number is equal to the number of protons and electrons. - Number of neutrons = Atomic mass of an isotope - Atomic number
A neon-20 atom has 10 protons and 10 neutrons within its nucleus, whereas neon-22 has 10 protons and 12 neutrons, making it an isotope.
Five protons makes this the element boron. The number of protons is the atomic number, and determines the identity of an element. This example would be the boron-12 isotope because it contains 5 protons and 7 neutrons.
The mass number is the number of protons plus neutrons. Magnesium is element number 12, so it has 12 protons. Its mass number with 14 neutrons is 12 + 14 which is 26.
