A calcium ion has 20 protons, the same as its atomic number. The number of electrons depends on the charge on the ion. For the most common calcium ion with a charge of +2, the number of electrons is 18; 20 - 18 = +2. The number of neutrons depends on the isotope that is ionized and is equal to the mass number of the isotope minus the atomic number of 20.

∙ 12y agoCalcium will always have 20 protons (its atomic number). Usually it will be in a +2 state as an ion which means it will have 18 electrons.so they have 15 nucleus

20 electrons

∙ 15y agoCalcium's atomic number is 20. Therefore, There are 20 protons in a Calcium atom (all in the nucleus, of course).
Wiki User
∙ 13y agoCalcium, no matter what form it is in, will always have 20 protons.
Though it generally forms a cation, not an anion.

How many protons and electrons are in an atom in calcium?
Calcium's atomic number is 20. That means that it has 20 protons. To make it neutral then, an atom of calcium must also have 20 electrons.
How many protons nucleus have?
It depends on what atom it is, the number of protons in the nucleus of an atom or ion defines what type of atom it is.
