The inferior alveolar nerve is the larger branch of the posterior division of the mandibular nerve. The inferior alveolar nerve enters the mandibular foramen in the ramus of the mandible (see the image below) to occupy the inferior alveolar canal in the body of the mandible.
The formula for the compound between Lithium and Sulfur is  Li2S because Lithium has a +1 charge while Sulfur has a -2. So for it to be stable, there needs to be two Lithium atoms attached to one Sulfer.
Formula and structure: The chemical formula of sulfuric acid is H2SO4 and its molecular weight is 98.079 g/mol. Its chemical structure is shown below. The sulfur atom is bound to two oxygen atoms through double bonds, and two hydroxyl groups (OH) through single bonds.
