Binary ionic compounds worksheet with answers – Welcome to the realm of binary ionic compounds! This comprehensive worksheet, meticulously crafted with a wealth of practice problems and detailed answer keys, will guide you through the intricacies of these fascinating chemical entities. Prepare to delve into the captivating world of ionic bonding and discover the fundamental principles that govern the formation, properties, and applications of binary ionic compounds.
Binary Ionic Compounds
Binary ionic compounds are chemical compounds composed of two elements, a metal and a nonmetal, that are held together by ionic bonds. Ionic bonds form when a metal atom loses one or more electrons to a nonmetal atom, creating positively charged metal ions and negatively charged nonmetal ions.
These ions are attracted to each other by their opposite charges, forming an ionic bond.
Examples of binary ionic compounds include sodium chloride (NaCl), potassium iodide (KI), and calcium oxide (CaO). These compounds are typically formed when a metal reacts with a nonmetal in a chemical reaction.
Naming Conventions for Binary Ionic Compounds
- The name of a binary ionic compound is written as the name of the metal followed by the name of the nonmetal, with the suffix “-ide” added to the nonmetal name.
- For example, the binary ionic compound NaCl is named sodium chloride.
- If the metal can form multiple ions with different charges, the charge of the metal ion is indicated using Roman numerals in parentheses after the metal name.
- For example, the binary ionic compound FeCl 2is named iron(II) chloride, indicating that the iron ion has a charge of +2.
Ionic Bonds: Binary Ionic Compounds Worksheet With Answers
Ionic bonds are formed when a metal atom loses one or more electrons to a nonmetal atom, creating positively charged metal ions and negatively charged nonmetal ions. These ions are attracted to each other by their opposite charges, forming an ionic bond.
Properties of Ionic Bonds, Binary ionic compounds worksheet with answers
- Ionic bonds are typically strong and have high melting and boiling points.
- Ionic compounds are typically soluble in water and conduct electricity when dissolved.
- Ionic bonds are non-directional, meaning that the ions can be arranged in any orientation without affecting the strength of the bond.
Comparison of Ionic Bonds to Other Types of Chemical Bonds
- Ionic bonds are stronger than covalent bonds, but weaker than metallic bonds.
- Ionic bonds are formed between metals and nonmetals, while covalent bonds are formed between nonmetals.
- Ionic bonds are non-directional, while covalent bonds are directional.

- Magnesium chloride (MgCl 2) is used as a deicing agent and in the production of magnesium metal.
- Sodium bicarbonate (NaHCO 3) is used in baking and as an antacid.
Key Questions Answered
What are binary ionic compounds?
Binary ionic compounds are chemical compounds composed of two elements, one metal and one nonmetal, held together by ionic bonds.
How are ionic bonds formed?
Ionic bonds are formed when a metal atom transfers one or more electrons to a nonmetal atom, creating positively charged cations and negatively charged anions, which are attracted to each other by electrostatic forces.
What are the properties of ionic bonds?
Ionic bonds are typically strong, resulting in compounds with high melting and boiling points. Ionic compounds are also good conductors of electricity when dissolved in water or melted.
