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.
Calcium 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
It has 20 protons and 20 neutrons.
20 electrons
Calcium's atomic number is 20. Therefore, There are 20 protons in a Calcium atom (all in the nucleus, of course).
Calcium, no matter what form it is in, will always have 20 protons.
Though it generally forms a cation, not an anion.
Atomic number of calcium is 20. So there are 20 protons in its nucleus.
20 i think :)

A calcium atom has 20 protons, 20 electrons and 20 neutrons
56 protons.
The atomic number is the number of protons in an atom's nucleus.
76 of them.
17
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.
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.
There are 24 Protons in Chromium's nucleus.

Lawrencium has 103 protons in the atomic nucleus.
There are four protons in the nucleus of a beryllium atom.
there are 80 protons in the nucleus of an atom of mercury
Californium has 98 protons.
Radon has 86 protons.
Bohrium has 107 protons.
56 protons.
In atoms, their can be as many protons as neutrons.So the answer is yes.
