If you mean the charge of an alpha particle, it's +2 since they're made up of 2 protons and 2 neutrons, protons having plus 1 charge, neutrons having 0.
Calcium typically has 20 protons, but with an added 2 charge, it now has 18 protons due to the loss of 2 positive charges. Calcium-41 has 41 - 18 = 23 neutrons. With a 2+ charge, it will attract 2 electrons, making it have 18 - 2 = 16 electrons.
For ( \text{Be}^{2+} ) (Beryllium), there are 4 protons, 2 neutrons, and 2 electrons. For ( \text{Na}^+ ) (Sodium), there are 11 protons, 12 neutrons, and 10 electrons. For ( \text{F}^{-1} ) (Fluorine), there are 9 protons, 10 neutrons, and 10 electrons. Lastly, for ( \text{S}^{-2} ) (Sulfur), there are 16 protons, 16 neutrons, and 18 electrons.
The Electrons and the Protons.
if you mean 2 valence electrons then it should be calcium because it is an alkaline earth metal and when you calculate the number of neutrons using the number of protons, 20 the atomic number, and the atomic mass, 40.078..rounded to 40, you get 20 neutrons.

2 protons and 2 neutrons. An alpha particle is the same as a helium nucleus.
The charge of an alpha particle is +2 as there are 2 protons and 2 neutrons

(a) a sodium atom with 11 protons, 11 electrons, and 12 neutrons (b) a calcium atom with 20 protons, 18 electrons, and 20 neutrons (c) a helium atom with 2 protons, 2 electrons, and 2 neutrons (d) an iron atom with 26 protons, 26 electrons, and 30 neutrons
An alpha particle is a helium nucleus. It consists of two protons and two neutrons so it has mass (approximately the same as the mass of a helium atom) and charge (a plus two charge because each proton has a charge of plus one and the neutrons are not charged).
Calcium typically has 20 protons, but with an added 2 charge, it now has 18 protons due to the loss of 2 positive charges. Calcium-41 has 41 - 18 = 23 neutrons. With a 2+ charge, it will attract 2 electrons, making it have 18 - 2 = 16 electrons.
The two subatomic particles found in the nucleus are protons and neutrons. Protons have a positive charge, while neutrons have no charge.

Mg has 12 protons, 12 electrons and 12 neutrons.Mg^2+ ion has 12 protons, 10 electrons and 12 neutrons. The number of protons and neutrons remains the same, but since the ion now has a 2+ charge, it has lost 2 electrons.
