The elements that will commonly form -2 anions are the chalcogens in group 16, otherwise known as the oxygen family. These elements are oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and radioactive polonium (Po).

Is carbonate in the periodic table?
Carbonate does NOT appear in the Periodic Table, because it is not an elementy, but an 'ANION'. The carbonate anion has the formula of 'CO3^(2-)'. That is the anion consists of one carbon and three oxygen atoms. Both Carbion and Oxygen are elements and appear in the Periodiuc Table.
What is an anion and what is the function of the liquid inside an anion?
An anion is a negative ion, i.e. one which is attracted to the anode during electrolysis. It's a particle, so it can't contain a liquid.
What is a charged particle called that forms when an atom transfers electrons?
An ion.If the atom loses electrons it becomes a positive ion, a cation.If the atom gains electrons it becomes a negative ion, an anion.
How does a polarised anion differ from an unpolarised anion?
Well the difference will be in the type of bond formed as a result. The bond would be Ionic in case of polarized anion and Covalent in case or unpolarised anion.The related link below also talks about the size of the anion and charge density in determining the bond type.
An ion that has a negative charge?
Chloride would be a negative ion in sodium chloride dissolved in water.
Is br a anion or cation?
Bromine forms the Br- anion
Is selenium cation or anion?
No. Selenium generally forms selenide (Se2-) ion
How do anion of nitrogen forms?
A nitrogen anion forms when a nitrogen atom gains three electrons, forming a nitride ion, N3-.
Does an anion always form a covalent bond?
No. An anion may contain covalent bonds, if it is a polyatomic anion, but an anion forms only ionic bonds if the anion's chemical integrity is maintained.
What toxic forms of oxygen is improperly paired with the detoxifying enzyme or molecule?
a Peroxide anion (O2-2)
What forms anion?
generally, non-metals
Is scandium a cation OR anion?
It forms a cation.
What forms an anion?
generally, non-metals
Is iron an anion or cation?
Iron forms a cation.
Is bismuth cation or anion?
Bismuth forms a cation.
Is cesium a cation or anion?
Cesium is an element that forms a cation.
What elements forms anions and why 1Silver 2Strontium 3Tin 4Iodine?
iodine forms iodide anion
