2019/2020 Chemical Bonding and naming Compounds

Master chemical bonding and naming compounds with our interactive worksheet! Practice ionic, covalent bonds, formulas & Lewis structures.

What causes atoms to form chemical bonds with other atoms? Atoms are more stable when they give away electrons. When two atoms get close together, they merge into one. The interaction of valence electrons forms a more stable configuration. The attraction of the nuclei for one another causes atoms to share electrons. How many atoms of oxygen are in one formula unit of aluminum sulfate Al2(SO4)3? 3 4 8 12 A nitride anion, N3-, has a charge of 3-. What is the charge of a titanium cation in the compound Ti3N2? 2+ 2- 3+ 3- Choose the correct word to fill in the blank to complete the paragraph. A compound is made of two or more elements that are chemically combined. The forces that hold atoms or ions together in a compound are called chemical bonds. There are two basic types of chemical bonding: ionic and covalent. Ionic bonds are formed by the transfer of electrons. Ionic bonds form between a metal and a nonmetal. Atoms joined by covalent bonds share electons. Covalent bonds form between a nonmetal and a nonmetal. Chemical Bond Sorting Sort the following characteristics based on whether it describes an ionic or covalent bond. Ionic Bond transfers electrons conducts electricity high boiling point high melting point crystal lattice structure Covalent Bond made up of molecules share electrons poor conductors of electricity low melting points low boiling points Ionic Compounds Match the following formulas to the correct ionic compound. Lithium Oxide LiO Beryllium Chloride BeCl2 Aluminum Fluoride AlF3 Covalent Compounds Prefixes Match the correct prefix with the correct number of atoms it represents starting in order from one to ten.
