The smallest numbers of ions of the proper kind that provide a correct elemental composition for the compound with electrical charges balanced. For example, magnesium cations have a charge of +2 and chloride anions have a charge of -1, so that two chloride anions and one magnesium cation are required to provide electrical neutrality, resulting in a formula of MgCl2.

Does the chemical formula of an ionic compound show the atoms in a molecule?
No, the chemical formula of an ionic compound does not show the atoms in a molecule. Instead, it represents the simplest ratio of ions in the compound. Ionic compounds exist as a lattice structure of alternating positive and negative ions, rather than discrete molecules.
Is the chemical formula KBr an ionic compound?
Yes, the chemical formula KBr represents an ionic compound. KBr is composed of a metal cation (K+) and a nonmetal anion (Br-) that are held together by ionic bonds due to the transfer of electrons from the metal to the nonmetal.
In a chemical formula for an ionic compound what is written first?
The cation, which is the positively charged ion, is written first in a chemical formula for an ionic compound.

An ionic compound is not represented by a molecular formula because an ionic compound?
An ionic compound is not represented by a molecular formula because it does not exist as discrete molecules. Instead, it exists as a three-dimensional array of positively and negatively charged ions held together by ionic bonds. The formula for an ionic compound represents the simplest ratio of the ions present in the compound.
A chemical compound is represented by what?
A chemical compound is represented by a specific combination of chemical elements bonded together in a specific ratio. This combination is represented by a chemical formula that shows the type and number of atoms of each element in the compound.
What is aluminum and oxygen ionic compound formula?
The ionic compound formed between aluminum and oxygen is aluminum oxide, with the chemical formula Al2O3. In this compound, aluminum (Al) has a 3+ charge, while oxygen (O) has a 2- charge. The formula represents the combining ratio of the two elements to form a stable compound.
