7 Chemical Bonds

Overview

Objectives

  • Define ionic and covalent bonding.
  • Predict which elements will gain or lose electrons.
  • Predict whether a compound has ionic or covalent bonds based on periodic table position.
  • Predict whether a compound has ionic or covalent bonds based on difference in electronegativity.
  • Draw Lewis Structures for covalent compounds.
  • Explain how physical properties such as boiling point are related to the strength of molecular attractions.
  • Memorize basic nomenclature rules and monoatomic and polyatomic ions.
  • Convert between formulas and names of ionic and covalent compounds as well as acids.

Academic Standards


C.1.6  Predict formulas of stable ionic compounds based on charge balance of stable ions.  Predict formulas and names using monoatomic and polyatomic ions.

C.1.7  Use appropriate nomenclature when naming compounds.
  • Write chemical formulas and name chemical compounds using the IUPAC system.
  • Predict formulas and names of binary compounds and oxyacids.
  • Predict formulas and names of binary covalent compounds.
C.1.28  Explain that chemical bonds between atoms in molecules, such as hydrogen, methane, ammonia, ethene, nitrogen, chlorine, and  many large biological molecules are covalent.

C.1.33  Use an element's location in the Periodic Table to determine its number of valence electrons, and predict what stable ion or ions an element is likely to form in reacting with other specified elements.
  • Determine electron configuration by position on the periodic table.
  • Construct Lewis-dot structures for elements using the periodic table.
C.1.34  Use the Periodic Table to compare attractions that atoms have for their electrons and explain periodic properties, such as atomic size, based on these attractions.
  • Demonstrate the relationship between periodicity and electronegativity, ionization energy, oxidation numbers, electron affinity, and chemical reactivity.
  • Predict molecular geometry of molecules including linear, trigonal planer, bent, trigonal pyramidal, and tetrahedral.
  • Understand polarity.
C.1.35  Infer and explain physical properties of substances, such as melting points, boiling points, and solubility, based on the strength of molecular attractions.

C.1.36  Describe the nature of ionic, covalent, and hydrogen bonds and give examples of how they contribute to the formation of various types of compounds.
  • Explain the driving force behind chemical bonding using the periodic table and the octet rule.
  • Differentiate between ionic and covalent bonding using electronegativity.
