Writing Formulas for Covalent Compounds

Writing Formulas for Covalent Compounds

Read each question carefully and provide the correct chemical formula or name as required. Remember to use prefixes correctly for covalent compounds.

Covalent compounds are formed when atoms share electrons to achieve a stable electron configuration. The prefixes used in their names indicate the number of atoms of each element present in the compound. For example, 'di-' means two, 'tri-' means three, and 'tetra-' means four.

Write the chemical formula for each of the following covalent compounds:

1. Carbon dioxide:  

2. Dinitrogen trioxide:  

3. Sulfur hexafluoride:  

4. Phosphorus pentachloride:  

5. Dihydrogen monoxide:  

Give the correct name for each of the following covalent compounds:

6. PCl₃

7. N₂O₄

8. SO₃

9. Cl₂O₇

10. Which of the following is the correct formula for carbon tetrachloride?

11. What is the name of the compound with the formula N₂O₅?

Indicate whether each statement is True or False regarding covalent compound nomenclature.

12. The prefix 'mono-' is always used for the first element if there is only one atom of that element.

13. Covalent compounds typically involve a metal and a nonmetal.

14. Explain the difference between naming ionic compounds and covalent compounds. Provide an example for each.
