Question

directions: utilize the rules for chemical nomenclature contained in chapter 5 of your text to complete this laboratory exercise. 1. binary ionic compounds are formed from the attraction of a metal cation (positive ion) and a nonmetal anion (negative ion). the name of a binary ionic compound is obtained by giving the name of the metallic element first, then list the stem of the nonmetallic element name, followed by -ide. nacl sodium chloride kf cas libr mgf₂ be₃n₂ na₂o kcl cao li₃p 2. writing formulas for binary ionic compounds from their chemical name is a two - step process. the first step is to write down the symbol and charge for each ion in the binary compound. the second step is to use subscripts to balance charge in the compound so that there are as many positive charges as negative charges: potassium oxide is an ionic compound formed from the k⁺ ion and the o²⁻ ion. in order to produce an ionic compound, there must be the same number of positive charges as negative charges. this is accomplished by having two k⁺ bonding to the single o²⁻. the ionic formula for potassium oxide is therefore k₂o. lithium fluoride lif calcium sulfide magnesium chloride hydrogen chloride beryllium fluoride magnesium nitride

Explanation:

Step1: Identify metal and non - metal

For naming binary ionic compounds, first identify the metal (cation) and non - metal (anion).

Step2: Apply naming rule

Name the metal first, then the non - metal stem + "ide".
For writing formulas:

Step1: Write ion symbols and charges

Write the symbol and charge of each ion in the compound.

Step2: Balance charges

Use subscripts to balance the positive and negative charges.
