Question

List four steps naming ionic compounds-

A) Identify the cation, name the anion, write the Roman numeral, indicate the charge

B) Determine the charge, name the cation, identify the anion, write the chemical formula

C) Name the cation, identify the anion, determine the charge, write the Roman numeral

D) Identify the anion, name the cation, write the chemical formula, indicate the charge

Answer 1

Naming ionic compounds involves identifying and naming the cation and anion, determining if a Roman numeral is needed to indicate a cation's charge, and writing the chemical formula with a balanced total charge.

Step-by-step explanation:

Steps for Naming Ionic Compounds

Naming an ionic compound involves several steps to ensure the correct chemical name is given. The appropriate steps to name an ionic compound are:

1. Identify the cation (the positively charged ion) and name it, which is usually a metal or a polyatomic ion like ammonium.
2. Identify the anion (the negatively charged ion) and name it, which is usually a nonmetal with an '-ide' ending or a polyatomic ion.
3. If the cation can have more than one possible charge, determine the charge based on the anion and write the Roman numeral to indicate its charge (this is needed only for cations with variable charge).
4. Write the chemical formula, ensuring that the total positive charge balances the total negative charge, reflecting the neutral nature of the compound.

For example, for the ionic compound FeCl₂, the correct name would be iron(II) chloride, which indicates that the compound consists of iron ions with a +2 charge and chloride ions with a -1 charge. The (II) represents the charge of the iron cation as a Roman numeral.

Correct naming is crucial for the proper identification of chemical substances and for clear communication in science.
