There will be a TEST next Friday on all of the concepts covered in Unit #3, including but not limited to: - Density (including definition, units, and how to calculate it) - Properties of Solids and Fluids (the definitions of the vocab, and how to apply that knowledge, ex: because you know the definition of tensile strength, you should be able ... The student knows how atoms form ionic, metallic, and covalent bonds. The student is expected to: The student is expected to: (7A) name ionic compounds containing main group or transition metals, covalent compounds, acids, and bases, using International Union of Pure and Applied Chemistry (IUPAC) nomenclature rules (RS);
The bases are known by their coded letters A, G, T, C. These bases always bond in a certain way. Adenine will only bond to thymine. Guanine will only bond with cytosine. This is known as the Base-Pair Rule. The bases can occur in any order along a strand of DNA. The order of these bases is the code the contains the instructions.

Concept Review with Key Terms. Chemical Bonds: A Preview—Chemical bonds form when the attractive forces between negatively charged electrons and positively charged nuclei exceed the repulsions between the nuclei to the maximum extent possible.
Concept Review: Covalent Bonds 1. A covalent bond forms when two or more valence electrons are attracted by the positively charged nuclei of two atoms and thus are shared between both atoms. 2. The H 2 molecule is stable because each hydrogen atom now has a shared pair of electrons and has achieved a stable noble gas configuration. 3.

Covalent bonds form when two or more nonmetals combine. For example, both hydrogen and oxygen are nonmetals, and when they combine to make water, they do so by forming covalent bonds. Nonmetal atoms in polyatomic ions are joined by covalent bonds, but the ion as a whole participates in ionic bonding.
