Naming Covalent Compounds Worksheet

Write the formulas for the following covalent compounds:

2) hexaboron silicide __________________________________


3) chlorine dioxide __________________________________


4) hydrogen iodide __________________________________


5) iodine pentafluoride __________________________________

Other studying ideas:

    1. Make flashcards of different vocabulary or concepts

    2. Make concept maps like the ones given out at the beginning of the unit (but expand with details)

    3. Create flowcharts for anything that can be seen as a process (how to name/write formulas for ionic and molecular bonds)

    4. Create tables to visually sort out differences between things like bonding, metals/nonmetals/metalloids etc.


Even if you don’t find that you would study from these things for the PAT, making them is an active way to get the information into your head.
