When writing the formula of an ionic compound we use the lowest whole number ratio of cations ([+] ions) to anions ([-] ions). If you look at a salt crystal you will see that each positive ion is surrounded on all 6 sides by negative ions, and that a crystal lattice forms. So it makes no sense to have a "molecular formula" for an ionic compound

Write the chemical formula for the ionic compound formed by each pair of ions. lithium hydrogen carbonate or lithium bicarbonate; Answers. 1. the ratio of each kind of ion in the compound. 2. Sometimes more than one ion is needed to balance the charge on the other ion in an ionic compound. 3.
A B Lithium is in group 1, so we know that it forms only the Li + cation, which is the lithium ion. Similarly, chlorine is in group 7, so it forms the Cl − anion, which is the chloride ion. C Because we begin with the name of the cation, the name of this compound is lithium chloride, which is used medically as an antidepressant drug.
4 · Lithium Ionic is a near-term producer of high-quality, low-cost lithium concentrate in Brazil''s ''Lithium Valley'', a region of global significance for hard-rock lithium production. Our claims span ~17,000 hectares in northeastern Minas Gerais State, a mining-friendly jurisdiction where +300 mines operate.
The formula for lithium bromide is (ce{LiBr}). This chemical formula says that there are one magnesium ion and two chloride ions in this formula.
