Naming Compounds Worksheet – Easy Difficulty
Naming Compounds Worksheet
Objective: Understand and practice the naming of different types of chemical compounds.
Instructions: Read each section carefully and complete the exercises that follow.
1. **Ionic Compounds**
Ionic compounds are formed when a metal reacts with a non-metal. The metal donates electrons to the non-metal, resulting in the formation of positive and negative ions, which attract each other.
Exercise 1: Name the following ionic compounds
a. NaCl
b. CaO
c. Al2S3
d. MgF2
2. **Covalent Compounds**
Covalent compounds form when two non-metals share electrons. The naming of these compounds often includes prefixes to indicate the number of each type of atom present.
Exercise 2: Name the following covalent compounds
a. CO2
b. N2O5
c. SF6
d. PCl3
3. **Acids**
Acids can be classified into two groups: binary acids (made of hydrogen and one non-metal) and oxyacids (made of hydrogen, a non-metal, and oxygen).
Exercise 3: Name the following acids
a. HCl (aqueous)
b. H2SO4
c. H3PO4
d. HF (aqueous)
4. **Polyatomic Ions**
Many compounds contain polyatomic ions, which are ions made up of more than one atom. Familiarity with common polyatomic ions is essential in naming compounds.
Exercise 4: Name the following compounds that contain polyatomic ions
