Magnesium is a chemical element with the symbol Mgand atomic number 12. That means the neutral atoms of Magnesium have 12 positively charged protons in their nucleus and 12 negatively charged electrons "orbiting" this nucleus. All atoms of magnesium have this structure.
However accompanying (stabilizing) the protons in the nucleus there are a number of electrically neutral neutrons and this is where atoms of magnesium can vary, there can be 12, 13 or 14 of these neutrons. making Magnesium isotopes (all of which are stable ie not radioactive).
24Mg comprising 78.99% of all the MG on Earth.
25Mg comprising 10.00% of all the MG on Earth.
26Mg comprising 11.01% of all the MG on Earth.
Thus all the atoms of Magnesium are chemically and electrically similar but they have different weights/masses.
The element with 13 neutrons is aluminum (symbol Al) which has an atomic number of 13.
Any atom of magnesium will have 12 protons.Neutral atoms of Mg-24 will have 12 neutrons and 12 electrons. Mg-25 has 13 neutrons and Mg-26 has 14 neutrons. A magnesium ion will have either 10 or 11 electrons.
It has 26 atoms . because Barium has 6 atoms and phosphorus has 4 and oxygen has 16 all in all it has 26 atoms.

The number of protons (p+) in the nuclei of an element's atoms is the atomic number of the element. In this case, the atomic number of magnesium is 12. In a neutral atom, the number of electrons (e-) equals the number of protons. So all neutral magnesium atoms have 12 protons and 12 electrons. Isotopes of an element differ in the number of neutrons (n0).There are three stable isotopes of magnesium (Mg) identified by their mass numbers; magnesium-24, magnesium-25, and magnesium-26. The mass number is the sum of protons and neutrons in the nucleus of an atom. To determine the number of neutrons, subtract the atomic number from the mass number. (mass number - atomic number = no. of neutrons)Magnesium-24: 24 - 12 = 12; An atom of Mg-24 has 12 p+, 12 e-, and 12 n0.Magnesium-25: 25 - 12 = 13; An atom of Mg-25 has 12 p+, 12 e-, and 13 n0.Magnesium-26: 26 - 12 = 14; An atom of Mg-26 has 12 p+, 12 e-, and 14 n0.

This would be magnesium, based on the number of protons. Since the protons is equal to the number of electrons it is a neutral atom. Given the number of protons in the atom, the isotope would be magnesium-26.
Manesium 24 has 12 electrons, protons and neutrons.
An unknown element contains 24 protons, 21 electrons,and has mass number 54
24
26 + 24 = 50
24 out of 26 = 92.31%
It has 26 atoms . because Barium has 6 atoms and phosphorus has 4 and oxygen has 16 all in all it has 26 atoms.
