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]

What element has 8 neutrons 8 protons?
The element that has 8 protons and 8 neutrons is oxygen.
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.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
What is the mass number of an atom with 11 protons 11 electrons 12 neutrons?
Sodium is a metal element. Mass number of it is 23.
How many neutrons are in magnesium 25?
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.
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.
What element has 12 protons and 10 neutrons?
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.
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.
What element has 8 neutrons 8 protons?
The element that has 8 protons and 8 neutrons is oxygen.
What's the atomic number of an element that has 12 protons and 14 neutrons?
6
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.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
What is the mass number of an atom with 11 protons 11 electrons 12 neutrons?
Sodium is a metal element. Mass number of it is 23.
How many protons and neutrons are in the element?
Neon has 10 protons and 9 neutrons.
An element's atomic mass number is?
It is about neutrons and protons. The total of neutrons and protons.
What element has 11 protons 12 neutrons 11 electrons?
This would be a Sodium-12 in ionic for or Na+
