formula of the molecular compound.

Practicing is the best way to learn how to name chemical compounds and write the corresponding formulas.

Chemists can have a sense of humor at times when naming

molecules. Some of the more classroom “appropriate” include, Draculin which is a

large glycoprotein found in vampire bat saliva. Penguinone, named from its similarity in 2D

structure to a penguin. The keto acid of morolic acid, isolated from the mora tree, is named moronic acid with derivatives called moronates, as in “which moron-ate all of the pie?” Traumatic acid is a plant hormone that causes injured cells to divide and help repair trauma to the plant. Uranium has resulted in

the creation of numerous silly names such as the uranium oxide anions known as urinates, uranium

nitrate which is also known as uranyl nitrate, and U4+ known as the uranous ion. 22 ©Hands-On Labs, Inc.

Experiment Naming Ionic and Molecular Compounds

Exercise 1: Preparation for Naming Ionic and Molecular Compounds In this exercise, you will color the periodic table and prepare note cards to learn common polyatomic ions and acids. You will also review tips for correctly naming ionic and molecular compounds.


1. Print the Periodic Table of Elements found here PeriodicTable.pdf.

2. Use colored pencils or photo editing software (i.e. Paint®, Microsoft Powerpoint®, Adobe Photoshop®) to color the groups of elements referenced in the legend boxes. Each group of elements should be represented by a unique color.

3. Color the legend boxes with the corresponding color used for each group.

4. Record your name and the date on the table. Then, take a photo of the colored periodic table, or save it as an image if you use photo editing software.

5. Resize and insert the image into Data Table 1 of your Lab Report Assistant. Refer to the appendix entitled “Resizing an Image” for guidance.

6. Write the name, formula, and charge for each of the common polyatomic ions in Table 2 of the Background onto individual note cards. Polyatomic ions that vary based on oxidation state, such as sulfate and sulfite, can be included on the same card, as shown in
