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.
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
A positive calcium ion (Ca^2+) has 20 protons, 18 electrons, and 20 neutrons. This is because the atomic number of calcium is 20, indicating 20 protons in a neutral atom, and losing 2 electrons makes it positively charged while the number of protons and neutrons remains the same.
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.
I don't want to do your homework for you. Here's how you figure it out: Protons = atomic number Neutrons = atomic mass - atomic number Electrons = atomic number + ionization
The nuclear symbol would be ^44Ti, representing the element titanium, since the atomic number (number of protons) is 22 (20 electrons + 2 protons) and the mass number (protons + neutrons) is 44 (22 protons + 24 neutrons).

1) it's spelt Calcium and 2) 20 protons, 20 electrons, 20 neutrons

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.
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.
The atom (^{44}_{20}\text{Ca}) contains 20 protons, 20 electrons, and 24 neutrons.
42 total mass -20 protons = 22 neutrons
The question is worded a little strangely, but if the alternate wording is correct I can answer. Calcium 45 has 20 Protons (like all calcium isotopes) and 25 Neutrons. That makes 65 up quarks and 70 down quarks. Electrons may vary with ionization, but will typically be 20.
