Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.
The cation would be C6H5NH3+ and the anion would be C6H5NH-
The symbol of the cation AuCl3 is [AuCl4]−, as gold(III) chloride typically exists as the complex anion [AuCl4]− with a +3 charge on the gold atom.
The cation of potassium cyanide is potassium (K+) and the anion is cyanide (CN-).
Boron is a metalloid element with the symbol B. In chemical compounds, boron tends to form covalent bonds rather than ionic bonds, so it does not typically exist as a cation or anion in its pure elemental form.
Can an ionic compound ever consist of a cation-cation or anion- anion bond? Explain.
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.

The cation would be C6H5NH3+ and the anion would be C6H5NH-
Al2O3 - aluminum oxide (dialuminium trioxide); this oxide is not a cation or anion but a chemical molecular substance.
The symbol of the cation AuCl3 is [AuCl4]−, as gold(III) chloride typically exists as the complex anion [AuCl4]− with a +3 charge on the gold atom.
The cation of potassium cyanide is potassium (K+) and the anion is cyanide (CN-).

Oxygen is neither a cation nor an anion. It is a neutral element.
CR is a cation.
