Concept Builders - Chemical Bonding and Molecular Shape
A Concept-Builder is an interactive questioning module that presents learners with carefully crafted questions that target various aspects of a concept. Each Concept Builder focuses the learner's attention upon a discrete learning outcome. Questions target that outcome from a variety of angles using multiple difficulty levels or varying activities. The following Concept Builders target concepts associated with Chemical Bonding and Molecular Shape.
Activities
🞋︎ Learning Goal: To identify the types of elements that undergo ionic bonding and to be able to describe the process that takes place when two elements form ionic bonds.
🞋︎ Learning Goal: To use electronegativity values to identify a bond as being polar or non-polar … and if polar, to identify the direction of the dipole moment vector.
🞋︎ Learning Goal: To identify correct and incorrect Lewis electron dot structures when given the formulas of molecular compounds.
Valence Shell Electron Pair Repulsion Theory
🞋︎ Learning Goal: To identify the Lewis electron dot diagram and the molecular shape of a variety of covalently-bonded molecules.
🞋︎ Learning Goal: To use electronegativity values, a Lewis structure, and an understanding of molecular shape to identify a molecule as being polar or non-polar.
