The atomic number of calcium is 20 and its electronic configuration is 2,8,8,2. Calcium atom tends to lose the 2 valence electrons and becomes positively charged calcium ion. Positively charged ions get attracted towards the cathode i.e. the negative terminal in an electric cell. Hence, positively charged ions are known as cations. Calcium is a cation.

What is the cation of calcium oxide?
Calcium and Oxygen are the atoms in Calcium Oxide.
What is the ratio of anion cation for 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.
Is scandium a cation or an anion?
Scandium is a cation because it tends to lose electrons to form a positive charge.

Is calcium an cation or anion?
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.
What is the cation of calcium oxide?
Calcium and Oxygen are the atoms in Calcium Oxide.
Is scandium a cation or an anion?
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.
The ions that are formed when calcium atom and oxygen atom react?
Calcium cation is Ca2+ and oxygen anion is O2-.
Is calciumcarbonate salt or acid?
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-).
Which atom becomes the anion in calcium chloride?
In CaCl2, Cl- is the anion while Ca2+ is the cation.
What is the valency of the compound calcium carbonate?
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.
When calcium and chloride bond to make calcium chloride does calcium become an anion and chloride a cation?
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.
What salt is ca no3 2?
Calcium nitrate is a salt that consists of the cation calcium (Ca2+) and the anion nitrate (NO3-).
