Common Ions and Formulae of Ionic Compounds

This is not a worksheet per se, but rather a reference sheet for your chemistry class. It displays a list of cations and anions along with their chemical symbols and net charges. Following the table is a pretty thorough explanation of how to combine these ions to form ionic compounds. This is a valuable tool to accompany your lesson on ionic compounds. Make sure to assign a few practice problems for homework!

Common Ions and Formulae of Ionic Compounds

Produced in the UK, this handout contains a chart of cations and anions. It explains how ionic compounds are formed and named. This is a concise and attractive handout that can be useful as a reference for your chemistry apprentices.

Common Ions and Formulae of Ionic Compounds

In this ionic compounds worksheet, students read about how to indicate the formulae for compounds with common ions.

Ionic Nomenclature

One document contains five different worksheets for practice naming and writing formulas for ionic compounds. The first is particularly notable, as it systematically walks beginning chemists through the process of using the periodic table to identify ions and combine them to form polyatomic ions. The remaining worksheets are not as neat in appearance and simply list names or chemical formulas for learners to practice with. They do, however, come with answer keys.

Chemistry Revision Themes: Quick Crosswords

A collection of 16 different chemistry crosswords provides variety in the ways that your class reviews chemistry vocabulary and concepts. Because the topics for each range from the introductory periodic table of elements to the complex energetics and kinetics, this resource is valuable to middle school and high school teachers alike. Each puzzle is comprehensive in coverage and has anywhere from 12 to 36 questions to answer. Add this to your library of review tools. US teachers, be aware that there are British spellings for some terms. In most cases, the US spelling requires the same number of letters as the British, so this shouldn't be a problem.

After the Test. . . Improving Understanding

The heading that tops this assignment is humourous, but specifically directed at a group of chemistry kids who apparently did not perform very well on an exam. The questions that follow are meant to review concepts that they need additional practice with. You could use the questions as a review for your own class, but you might want to replace the blurb at the top with something more personal. The topics covered by the multiple choice questions include binary molecular compounds, oxidation states, anions and cations, and writing molecular formulas.

Naming Compounds Handout

In this naming compounds worksheet, students read through guidelines on naming different types of chemical ions and compounds then practice naming on their own. The naming compounds handout includes 100 practice problems in which they name ions, combine pairs of ions to make new formulas, write the ions and chemical formulas for compound names, name molecular compounds, name acids, and finish with naming additional chemical compounds by applying all they have studied in the packet.

Covalent Compound Scavenger Hunt

In this chemistry worksheet, students look for the covalent compounds while examining the objects in the classroom. They also apply the knowledge of formulas.

Chemical Nomenclature

Students study the chemical symbols and memorize the elemental symbols.  In this formulas instructional activity students determine the empirical and molecular formulas of compounds. 

Ternary Compounds

Practice naming ternary compounds with this PowerPoint presentation. Individual slides show the patterns for memorizing the nomenclature for polyatomic ions. Several examples are included for student practice. This thorough and cleverly-designed slideshow is strong enough to use as a foundation for your lecture.
