Name the following ionic compounds:(h) Cr 2 (CO 3 ) 3

Hey everyone. Our question here is asking us to provide the name for the following compound. As we know, we know that copper is a transition metal so we can have more than one possible charge. So we can label that charge as X. For now. And we also have a sign which is one of our poly atomic ions. So we know that this has a -1 charge. And since our compound is neutral, we know that this will be equivalent to zero. So we have -1 plus x. And when we saw for X, we end up with x equals plus one. So the name of our compound is going to be copper one in Roman numeral and in parentheses since it's a transition metal bio sign, and this is going to be our final answer. So I hope this made sense. And let us know if you have any questions.

Name the following ionic compounds:(h) Cr₂(CO₃)₃

Verified step by step guidance

Step 1: Identify the cation and the anion in the compound. In this case, the cation is Chromium (Cr) and the anion is Carbonate (CO3).

Step 2: Determine the charge of the cation and anion. The charge of the carbonate ion is -2. The subscript 21 in front of Cr indicates that the charge of the chromium ion is +21.

Step 3: Write the name of the cation first, followed by the name of the anion. The name of the cation is Chromium(21) and the name of the anion is Carbonate.

Step 4: Combine the names of the cation and anion to get the name of the ionic compound. The name of the ionic compound is Chromium(21) Carbonate.

Step 5: Note that the number in parentheses after the name of the metal (Chromium) indicates the charge of the ion. This is used when the metal forms more than one ion, which is the case for most transition metals like Chromium.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Ionic Compounds

Ionic compounds are formed when atoms transfer electrons, resulting in the formation of positively charged cations and negatively charged anions. These oppositely charged ions attract each other, creating a stable ionic bond. Understanding the composition and naming conventions of ionic compounds is essential for accurately identifying them.

Oxidation States

Oxidation states, or oxidation numbers, indicate the degree of oxidation of an atom in a compound. They help in determining how many electrons an atom has gained, lost, or shared during the formation of a compound. In the case of complex ions like Cr21CO323, knowing the oxidation states of chromium and carbon is crucial for proper naming.

Nomenclature of Ionic Compounds

The nomenclature of ionic compounds involves specific rules for naming the cations and anions present in the compound. Typically, the cation is named first, followed by the anion, with the anion's name often modified to end in '-ide', '-ate', or '-ite' depending on its composition. Familiarity with these naming conventions is necessary to accurately name compounds like Cr21CO323.
