Name each ionic compound. a. Mg 3 N 2 b. KF c. Na 2 O d. Li 2 S f. KI e. CsF

Hey everyone, let's go ahead and practice naming the positive ions involved in each compound. So starting off with a, we see that we have capital M. G. O. And we know that M. G. Stands for magnesium and magnesium is going to have that plus two charge. And that's because it's in our group to a medals. And when we name this compound it's going to be magnesium oxide. Moving on to be we have K two S. 04. So we can see that we have potassium and potassium is going to have that plus one charge. And that's because it's in our group one a. And when we name this, we name it as potassium sulfate since our an ion is sulfate. Moving on to see we have N A B R. 04, so N A. Is sodium And we know that it has a plus one charge since it's in our group one a. And when we name this, we named this as sodium per bromate and perp Rome is one of our poly atomic and ions moving on to D. We have C. O. Parentheses 32. And we know that Ceo stands for cobalt. So we're going to write COBOL but we also need to be aware that cobalt is a transition metal. So we can have multiple charges. So looking at our an ion, we know that nitrate has a -1 charge and we see that it has a subscript of two. So this is telling us that Cobalt needs a plus two charge in order to balance out that nitrate. And when we name this we're going to name it as cobalt two nitrate. So we're going to denote the charge with our roman numerals. And lastly looking at E, we have MNOH two. So we know that Mn is manganese and again, manganese is a transition metal, so it can have more than one possible charge. So looking at our an ion, we know that ohh is going to be O H minus. and since we have that subscript of two, That means we have a plus two charge for manganese. And when we name this, we're going to name it as manganese two hydroxide. And this is going to be our final answers. So I hope this made sense. And let us know if you have any questions.

Name each ionic compound. a. Mg₃N₂ b. KF c. Na₂O d. Li₂S f. KI e. CsF

Verified step by step guidance

Identify the cation and anion in the compound. In Na2O, Na is the cation (sodium) and O is the anion (oxide).

Determine the charge of each ion. Sodium typically forms a +1 charge, and oxygen typically forms a -2 charge.

Check the balance of charges to confirm the formula. Here, two sodium ions each with a +1 charge balance one oxide ion with a -2 charge.

Name the cation by its element name, which is Sodium.

Name the anion by taking the root of the element name and adding the suffix '-ide', resulting in 'oxide'. Thus, the name of the compound is Sodium oxide.

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 compound. Common examples include sodium chloride (NaCl) and magnesium oxide (MgO). Understanding the formation and properties of ionic compounds is essential for naming them correctly.

Nomenclature of Ionic Compounds

The nomenclature of ionic compounds involves specific rules for naming the cations and anions. Typically, the cation is named first, followed by the anion. For example, in Na2O, sodium (Na+) is the cation and oxide (O2-) is the anion. The name of the compound is derived from these ions, resulting in 'sodium oxide' for Na2O.

Oxide Ions

Oxide ions are negatively charged ions formed when oxygen gains two electrons, resulting in O2-. They are commonly found in various ionic compounds, particularly with metals. In the case of Na2O, the oxide ion combines with sodium ions to form a stable ionic compound. Recognizing the role of oxide ions is crucial for understanding the properties and naming of compounds like Na2O.
