Covalent (or Molecular) Compounds Practice
(i.e., nonmetal-nonmetal combinations)

Write the correct name for each of the following compound

Page 2: Fixed-Charge Cations Practice

This section covers ionic compounds containing fixed-charge cations, presenting a comprehensive set of exercises for both naming compounds and writing formulas.

Definition: Fixed-charge cations are metal ions that form only one type of positive ion.

Example: NaBr is named sodium bromide because sodium only forms Na⁺ ions.

Highlight: The practice includes polyatomic ions such as ammonium (NH₄⁺) and complex anions like permanganate (MnO₄⁻).

of 8

Page 3: Variable-Charge Cations Practice

This page focuses on naming and writing formulas for compounds containing transition metals that can form multiple different ionic charges.

Definition: Variable-charge cations are metal ions that can form different positive charges, requiring Roman numerals to specify the charge.

Example: CuBr is named as copper(I) bromide, where (I) indicates the +1 charge on copper.

Highlight: The exercises emphasize the importance of correctly identifying and noting the charge of transition metal ions.

of 8

Page 4: Ion Identification Practice

This section teaches how to identify and count ions present in chemical formulas, providing a systematic approach to understanding ionic compounds.

Definition: Ionic compounds consist of positively charged cations and negatively charged anions in ratios that create a neutral compound.

Example: In CoBr₂, there is one Co²⁺ cation and two Br⁻ anions.

Highlight: The practice emphasizes writing ion counts without using "1" and properly balancing charges.

of 8

Page 5: Acid Nomenclature Practice

This page covers the systematic naming of acids and writing their chemical formulas.

Definition: Acids are compounds that produce hydrogen ions (H⁺) when dissolved in water.

Example: HBr forms hydrobromic acid in water, while HBrO₃ forms bromic acid.

Vocabulary: The "-ic" suffix indicates the more common oxidation state, while "-ous" indicates the lower oxidation state.

of 8

Page 6: Additional Practice

This final section provides mixed practice problems combining various types of chemical nomenclature.

Example: Ca₃N₂ is named calcium nitride, demonstrating ionic compound nomenclature.

Highlight: The problems integrate concepts from previous sections, reinforcing overall understanding of chemical nomenclature.

of 8

Page 6: Additional Practice #1

This section provides comprehensive practice combining various types of compounds, including ionic compounds, covalent compounds, and acids.

Example: Nb₂O₃ is named as niobium(III) oxide.

Highlight: This section reinforces the importance of distinguishing between different types of compounds when naming them.

of 8

Page 7: Additional Practice #2

Continues with more advanced practice problems, incorporating all previously covered concepts.

Example: Fe(MnO4)₃ is named as Iron(III) Permanganate.

Highlight: Complex ionic compounds often contain polyatomic ions that must be correctly identified for proper naming.

of 8

Page 1: Covalent Compounds Practice

This page focuses on the nomenclature of covalent (molecular) compounds formed between nonmetals. The practice exercises are structured to reinforce understanding of systematic naming conventions.

Definition: Covalent compounds are molecules formed by sharing electrons between nonmetal atoms.

Example: P₂O5 is named as diphosphorus pentoxide, where 'di-' indicates two phosphorus atoms and 'pent-' indicates five oxygen atoms.

Highlight: The practice includes both naming compounds from formulas and writing formulas from names, providing comprehensive practice in both directions.

Vocabulary: Prefixes used in naming $mono-, di-, tri-, tetra-, penta-, hexa-$ indicate the number of atoms present.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha KlichAndroid user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
