This image presents a worksheet titled "Properties of Ionic and Covalent Compounds." The task is to match the properties listed at the bottom with the correct column for either "Ionic Compounds" or "Covalent Compounds."
To solve this, I need to use my knowledge of chemistry to correctly categorize each property. I will go through each row in the table and assign the appropriate properties from the list below.
Here is the completed solution:
Ionic Compounds:
*
Structure: Crystal Lattice
*
Boiling Point: High Boiling Point
*
Melting Point: High Melting Point
*
Solubility: Soluble in Water
*
Conductivity: Good conductor (when dissolved or molten)
*
Formation: Transfer Electrons
*
Types of Elements: Metals and Nonmetals
*
State of Matter at Room Temp: Solids
*
Texture: Hard/Brittle
Covalent Compounds:
*
Structure: Lewis Structure
*
Boiling Point: Low Boiling Point
*
Melting Point: Low Melting Point
*
Solubility: Solubility Depends on Polarity
*
Conductivity: Poor Conductors
*
Formation: Share Electrons
*
Types of Elements: Nonmetals
*
State of Matter at Room Temp: Liquids and Gases
*
Texture: Soft/Flexible
This categorization is based on fundamental chemical principles. Ionic compounds are formed by the transfer of electrons between metals and nonmetals, creating a strong electrostatic attraction that results in a crystal lattice structure. This strong bonding leads to high melting and boiling points, and they are typically hard and brittle solids at room temperature. They conduct electricity when dissolved or melted because their ions are free to move. Most are soluble in water.
Covalent compounds are formed by the sharing of electrons between nonmetals. The bonds are generally weaker than ionic bonds, leading to lower melting and boiling points. They can be gases, liquids, or soft solids at room temperature. They are poor conductors of electricity because they do not have free ions or electrons. Their solubility varies depending on their polarity; polar covalent compounds may dissolve in water, while nonpolar ones do not.
