IONIC VS. COVALENT COMPOUNDS PROPERTIES OF MOLECULES Exist as solids, liquids or gases at room temperature Solids are often soft and waxy Liquids and solids often are volatile and can evaporate readily [ie. Perfume or mothballs] Low melting and boiling points Low solubility in water and other p...
Lab: Properties of Ionic and Covalent Compounds Introduction: Ionic compounds (or salts) are formed when metals transfer electrons to nonmetals. The loss of electrons by the metal atom transforms it into a positive ion, orcation. The gain of electrons by the nonmetal atom transforms it into a...
Ionic vs. Covalent Bonds Summary Here's a quick summary of the differences between ionic and covalent bonds, their properties, and how to recognize them: Test Your Knowledge of Ionic and Covalent Bonds Think you fully understand the differences between ionic and covalent bonds? Test your comprehen...
In this lesson we will discuss what happens when we dissolve two different types of compounds in liquids: ionic and covalent solutes. The chemical differences between these solutes affect the properties of the solutions they form. Introduction ...
