Potassium Iodide, symbol K+I-
K+ (19) - 1 = 18 electrons and 18 * 3 = 54, so
I- (53) + 1 = 54 electrons
The chemical formula for the cation in the compound Cr(CO3)2 is Cr2 and for the anion is CO32-.
The chemical formula for the cation in the compound Cr(CO3)3 is Cr3 and for the anion is CO32-.
Typically in writing an ionic compound, the cation is written first, then the anion.
Can an ionic compound ever consist of a cation-cation or anion- anion bond? Explain.
A single element cation and single element anion form a binary ionic compound, where one element is a metal and the other is a nonmetal. The metal forms the cation by losing electrons, while the nonmetal forms the anion by gaining electrons. Examples include NaCl (sodium chloride) and KBr (potassium bromide).

Typically in writing an ionic compound, the cation is written first, then the anion.
An example of a binary ionic compound where both the anion and cation have 10 electrons is lithium fluoride (LiF). Lithium is a cation with 3 electrons, and fluoride is an anion with 9 electrons. When lithium loses an electron and fluoride gains an electron, they form LiF with both having 10 electrons in their outer shells.
Cation because it gives away its valence electrons in order to form an Ionic Compound, ie. LiCl

An ion can be either a cation or an anion, depending on whether it carries a positive or negative charge, respectively. Cations have a positive charge because they have lost electrons, while anions have a negative charge because they have gained electrons.
When you mix a metal cation with a nonmetal anion, they will form an ionic compound through ionic bonding. The metal cation will donate electrons to the nonmetal anion, resulting in the formation of a stable compound with a neutral charge. This compound will have a crystal lattice structure and exhibit properties different from those of the individual elements.
The cation (positively charged ion) typically goes first in writing a chemical formula, followed by the anion (negatively charged ion). This convention helps identify the structure of the compound and how the elements interact with each other.
A cation has extra protons and it is positively charged. An Anion has extra electrons and it is negatively charged. From, your question, it is an anion.
