Electrons have no relevant mass, and protons and neutrons both have the mass of 1u.
If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u.
Core Mass - Protons = Neutrons
40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.

How many protons neutrons and electrons are in Francium?
Francium has 87 protons and electrons; the number of neutrons is different for each isotope and francium has ca. 40 isotopes ad isomers. Number of neutrons = Atomic mass of the isotope - 87
How many protons electrons and neutrons in calcium-44?
Ca-46 is an isotope of the calcium found on the periodic table. The atomic number is equivalent to how many protons the atom has and tells the identity of the element, if the number of protons is changed/ atomic mass number, the element would transmutate into another element. Thus, Ca always has 20 protons. Because it is not Ca++ or Ca- it is not changing the charge so no electrons are moving either. This means the number 46 is refering to a change in neutron in the nucleus of the atom, hence it is called an isotope. 46 is the number of protons plus neutrons so the isotope of Calcium has 20 protons, 20 electrons and 26 neutrons, or 46-20=26. Hope this clarifies things.
How many electrons are lost or gained in the element Ca as it changes into simple ions?
You already gave the answer yourself. You see, ions don't change the number of protons and neutrons of an atom. It only changes the number of electrons. Ca originally has 20 electrons, protons, and neutrons. If it becomes ionic; two of the electrons disappear, but the amount of protons and neutrons are still the same. Now since the two electrons disappear, you place a "2" behind the letters "Ca". And now because the amount of negativily charged particles (electrons) are less than positively charged particles (protons), the atom becomes positive! Hence the plus sign after the number "2"? So the answer to your questions is 20. The only time the amount of protons and neutrons can change in an atom, is by the process of nuclear fission or fusion.
How many protons electrons and neutrons are there in the isotopes of calcium?
For the Calcium isotope with atomic number 20 and with isotope or mass number 40, each atom has 20 protons, 20 electrons and 20 neutrons.This can be found easily as the atomic number of any atom = number of protons (20) and also = number of electrons(20) as each atom is electrically neutral so the +proton number has to equal the - electron number.The atomic mass number (or isotope number) = number of protons + neutrons combined so in the case of calcium 40 = 20 + number of neutrons. This makes the number of neutrons 20.Added:Other isotopes (about 3%) of (natural occurring) Calcium are with 22, 23, 24, 26 or 28 neutrons.All Calcium isotopes have 20 protons and 20 electrons.

Chemical with 11 protons and 10 electrons is?
The chemical element with 20 protons and 20 neutrons is Calcium(Ca). The number of protons is equal to the number of electrons, and the number of electrons is equal to the atomic number.
How many neutrons are found in an atom with atomic mass of 20?
Neon (Ne) has at. wt. of 20.183 and at. no. of 10.We know that the number of Protons is equal to At. No. and the number of Electrons equals the number of Protons.The number of Neutrons is the (At. Wt.) - (At. No.)Thus, we know that Ne has 10 Protons, 10 Electrons and 10 Neutrons.
What is the element that has 20 neutrons?
Several can. Perhaps you meant to ask which has 20 protons, in which case the answer is calcium. (Calcium is also one of the elements that can have 20 neutrons, but it's not the only one.)
How many protons and electrons does a calcium atom have?
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.

How many neutrons does the isotope Ca have?
42 total mass -20 protons = 22 neutrons
