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.

Can an element have the same number of protons and neutrons?
Yes. An example would be carbon-12. It has 6 protons and 6 neutrons.
If an atom of an element has a mass number of 31 and 16 neutrons in its nucleus what is the atomic number of the element?
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.
How many neutronselectrons and protons does magnisium ion has?
Neutrons-12 Protons -12 Electrons-10
Which has more isotopes neon -10 or neon-12?
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.
What element has 11 protons 12 neutrons 11 electrons?
This would be a Sodium-12 in ionic for or Na+
What element has 12 protons 14 neutrons 10 electrons?
Magnesium2+ because it donated 2 electrons
Which of the following nuclei would be the most stable A. 10 protons , 14 neutrons B. 10 protons, 15 neutrons C. 10 protons, 13 neutrons D. 10 protons, 12 neutrons.?
(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.

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.
what element has 10 protons 10 electrons and 12 neutrons?
it is the most stable isotope of sodium Na.
What nuclei would be the most stable?
10 protons, 12 neutrons
How many neutronselectrons and protons does magnisium ion has?
Neutrons-12 Protons -12 Electrons-10
What's the atomic number of an element that has 12 protons and 14 neutrons?
6
How many protons neutrons and electrons would an atom of neon have?
- 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
How are neon 22 and neon 20 alike?
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.
What is the identity of an element with 5 protons 7 neutrons and 5 electrons?
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.
What is the mass number of a magnesium atom with 14 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.
