Yes, a cation and an anion can be isoelectronic if they have the same number of electrons. For example, in the third period of the periodic table, a sodium cation (Na+) and a fluorine anion (F-) are isoelectronic because they both have 10 electrons.
An example of an ionic compound with a polyatomic cation and anion, where the atoms in the anion are all from the same group, is ammonium phosphate (NH4)3PO4. Here, the cation is the ammonium ion (NH4+), a polyatomic cation, and the anion is the phosphate ion (PO4^3−), which contains phosphorus and oxygen, both belonging to Group 15 and Group 16 of the periodic table, respectively. However, the phosphate itself does not have all its atoms from the same group; for a strict interpretation, consider a compound like ammonium sulfate ((NH4)2SO4), where the sulfate ion (SO4^2−) has sulfur from Group 16 and oxygen from Group 16 as well.

Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.
cation is positively charged ion. metals lose electrons to form cations.
An example of this type of compound is ammonium sulfate (NH4)2SO4, where the polyatomic cation is ammonium (NH4+) and the polyatomic anion is sulfate (SO4^2-). In this case, the atoms in the sulfate anion are all from the same group in the periodic table (Group 16 or the oxygen family).
One example of an ionic compound meeting these criteria is Ca(NO3)2, where the cation is Calcium with 20 electrons and the anion is nitrate (NO3-) consisting of nitrogen and oxygen, which are in the same group on the periodic table.
Yes, a cation and an anion can be isoelectronic if they have the same number of electrons. For example, in the third period of the periodic table, a sodium cation (Na+) and a fluorine anion (F-) are isoelectronic because they both have 10 electrons.
Divalent cation: Ca2+ Trivalent anion: (PO4)3-
Group 15 elements will typically bond as an anion to a cation from groups 1,2, or 13. They can also bond covalently to any of the elements from groups 13-17.
Potassium will most likely form a cation with a +1 charge.

Sodium is an elemental metal, found in the Periodic Table. When it ionises( looses) an electron it becomes the Sodium CATION (Na^(+)). Remember ions that have a positive charge are CATIONS, and ions that have a negative charge are ANIONS. Slo the chloride ion (Cl^-) is an ANION. Collectively they are ions.
An anion is a negatively charged ion that forms when an atom gains electrons. Anions are typically found on the right side of the periodic table among nonmetals.
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.
Neither, heluim is inert, one of the noble gases.
