It has 20 protons, irrespective of its charge.
Yes. The charge of a cation tells how many more protons than electrons it has. For example Fe3+ has three more protons than electrons. However these protons were not gained, since an element always has the same number of protons no matter what its charge is. So in order for an element to have more protons than electrons it has to lose the electrons.
A "cation" carries positive (+) charge. An "anion" caries a negative (-) charge. The charge carried in may be single or multiple.
Ca (2+) I think because since there are two less electrons then the charge would become positive.
20 protons, 18 electron's, and 20 neutrons
CaO. The charges of the and the cation (the positive element, Ca) and the anion (the negative element, O) must add up to zero.
I am going to borrow heavily from the answer to "Why do electrons have a negative charge?" Protons have a positive charge because the charge is part of what the particle is made of. If it were possible to remove the positive charge from the proton we would then have a neutron.

Calcium (Ca) contains: 20 protons (positively charged) 20 neutrons (neutral) Outside of the nucleus: 20 electrons (negative charge) with the configuration 2-8-8-2 Calcium has an atomic mass of 40.08
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.
Ca2+ is positively charged. Remember that an electron is a particle with negative charge; therefore, the element Calcium (Ca) has LOST 2 electrons in order to be positive 2.
The number of protons in an element does not depend on the charge of the element. An atom of a given element has the same number of protons as an isotope of that element. Thus, a calcium ion has 20 protons, just like atoms in calcium metal.
A "cation" carries positive (+) charge. An "anion" caries a negative (-) charge. The charge carried in may be single or multiple.
This formula is Ca(H2PO4)2. Since a dihydrogen phosphate anion has only one negative electric charge and a calcium cation has a positive charge of two, twice as many of the anions are required.
Ca (2+) I think because since there are two less electrons then the charge would become positive.
42 total mass -20 protons = 22 neutrons
20 protons, 18 electron's, and 20 neutrons
There are 20 protons in a calcium atom. You can find the number of atoms in any element by looking at the atomic number which is in the top right corner of the element's box on the periodic table. e.g. Ca 20 40.078
