The Calcium Atom for the Calcium Cation , by ionising two(2) electrons.
Ca(g) = Ca^(2+)(g) + 2e^-
Calcium chloride is a salt; calcium is the cation and chloride the anion.
Calcium and Oxygen are the atoms in Calcium Oxide.
Cation:Anion :: 1:1 : Ca^(2+) : O^(2-) The charges balance at '2' , but are opposite (+/-) Because they are opposite, they come together like the N & S poles of a magnet, to form the ionic compound 'CaO ' Calcium oxide/lime.
Scandium is a cation because it tends to lose electrons to form a positive charge.
Can an ionic compound ever consist of a cation-cation or anion- anion bond? Explain.

As the elemental metal, calcium is neither a cation nor an anion. Its elemental symbol is 'Ca(s)' . 's' indicating that it is solid. However, like sodium , calcium readily ionises ( loses) 2(two) electrons. Symbolically it is now 'Ca^(2+) ' . It is an ION. Because it is a positive(+) ion , it is known as a 'CATION'. Compare to chlorine, it has electron affinity, and symbolically it is ' Cl^(-) ' . It is also an ION. But because it is a negative (-) ion , it is known as an ANION. So remember. any atom that loses or gains electrons, is no longer an atom, but an ION. If the ion is positively(+) charged, then it is a CATION , and if the ion is negatively(-) charged , then it is an ANION.

Calcium cation is Ca2+ and oxygen anion is O2-.
A Salt. Chemical salts are of the form 'metal cation' and Acidic Anion'. The general formula is given as M^(n+)A^(m-). In calcium carbonate the metal cation is calcium (Ca^(2+)) and the Acidic anion is CO3^(2-).
In CaCl2, Cl- is the anion while Ca2+ is the cation.
The valency of calcium carbonate is 2. Calcium has a valency of 2 as it can lose two electrons to form a stable cation, and carbonate has a valency of 2 as it can accept two electrons to form a stable anion.
No, in the compound calcium chloride, calcium remains a cation with a 2+ charge, and chloride remains an anion with a 1- charge. They bond through an ionic bond where calcium donates its two electrons to chlorine.
Calcium nitrate is a salt that consists of the cation calcium (Ca2+) and the anion nitrate (NO3-).
