Descriptions
- Compare and contrast covalent and ionic bonding.
Explain metallic bonds.
Describe the molecular structure of a compound.
Name the intermolecular forces and explain their affects on properties.
Identify the structure and properties of water.
Generalizations:
• Elements bond in various ways in order to become more stable.
Different types of bonds produce compounds or molecules with different properties.
Vocabulary:
Core, Components, Ionic, Covalent
Metallic, Octet, Electronegativity, Polarity
Dot diagrams, Double bonds, Triple bonds, Resonance, Coordinate covalent, bonds
TEKS
(8) The student knows how atoms form bonds to acquire a stable arrangement of electrons.
(A) identify characteristics of atoms involved in chemical bonding;
(B) investigate and compare the physical and chemical properties of ionic and covalent compounds;
(C) compare the arrangement of atoms in molecules, ionic crystals, polymers, and metallic substances; and
(D) describe the influence of intermolecular forces on the physical and chemical properties of covalent compounds.
(12) The student knows the factors that influence the solubility of solutes in a solvent.
(C) evaluate the significance of water as a solvent in living organisms and in the environment.
to be reviewed: BIO 1-3, IPC 1-3, IPC 9A Relate the structure of water to its function [as the universal solvent this terminology is not assessed]. IPC 7D Relate the chemical behavior of an element including bonding, to its placement on the periodic table.
BIO 12A analyze the flow of energy through various cycles including the carbon, oxygen, nitrogen, and water cycles
B.2B, I.3A, I.9A (10th) & B.2A, B.2B, B.2D, I.3A, I.3B, I.7D, I.9A (11th)
