How many protons, neutrons, and electrons are in 24 +2

Mg
12 is it 12p, 14e- or 10 e?

Mg is atomic number 12. So the mass number of 24 has 12 protons and 12 neutrons since mass number = protons + neutrons. The neutral atom has 12 electrons, also; therefore, the 2+ ion will have 10 electrons.

You can check out your answers this way. (You already know 12 p is correct.)
Since the charge of the neutral atom must be zero
12+ for protons
12- for electrons
-----
0 charge for atom.
Take your answers of 10e and 14e.
12+ for protons
14- for electrons
-----
2- charge and you wanted 2+ charge. Try the other.

12+ for protons
10- for electrons
-----
2+ charge which is what you wanted.

thanks.

The charge and identity of an ion with 16 protons, 18 electrons and 17 neutrons would be?

To determine the number of protons, neutrons, and electrons in an atom, you need to look at its atomic number and atomic mass.

In the case of the Mg ion you provided (+2 means it has a charge of +2), you need to consider the neutral form of the atom. The atomic number of magnesium is 12, which means it has 12 protons. This number does not change, regardless of whether the atom is charged or not.

The atomic mass of magnesium is typically reported as about 24, but this does not represent the actual number of protons and neutrons. Instead, it represents the average atomic mass of all the natural isotopes of magnesium. To find the number of neutrons, you subtract the number of protons from the atomic mass.

So, for Mg, the number of protons remains 12. To find the number of neutrons, you subtract 12 (number of protons) from approximately 24 (atomic mass): 24 - 12 = 12 neutrons.

Now, since the ion has a charge of +2, it means it has lost 2 electrons. When an atom loses electrons, it becomes positively charged. So, for Mg+2, the number of electrons would be 12 (number of protons) - 2 (charge) = 10 electrons.

Therefore, in the Mg+2 ion, it has 12 protons, 12 neutrons, and 10 electrons.
