A very neat worksheet has been produced by Pearson Education, Inc. for use in a general chemistry class. The first nine questions are fill in the blanks for a paragraph about types of bonds and electronegativity. Five true-false questions and five matching descriptions follow. This would make an ideal pop quiz!
Five pages provide extensive exercise when studying covalent bonding and molecular geometery. College level or AP chemists relate bond length and strength, order elements in terms of electronegativity, fill in data tables describing molecular shape and bond angles, and draw Lewis structures for a variety of compounds. Use this as a chapter review or exam.
This is simply a reading passage about how covalent bonds are formed and what makes them polar. Keep this on hand for chemistry kids who happen to be absent on the day that you teach these concepts. There are three questions addressing them at the top the page that are answered within the text.
Four pages provide plenty of problem solving practice for chemistry whizzes. They answer questions and write electron configurations for ions. They use Lewis dot diagrams to display equations. Covalent bonds are explored. The last half of the assigment is made up of a chart in which learners write the number of valence electrons, the Lewis structure, molecular shape, bond angles, polarity, and resonance.
Here you have four slightly different versions of a chemistry quiz that you can give on the same day. The topics covered are nuclear charge, ionization energy, atomic size, par bonds, Lewis electron dot stuctures, quantum numbers, and the periodic table of elements. The level of the questions makes this quiz geared toward college or AP chemistry courses.
This simple chemistry assignment sports a chart for learners to complete showing the change in electronegativity and the type of bond displayed by a Lewis dot structure. Learners consider electronegativity values and state what type of bond will form. Give this out as a review or a pop quiz in your high school general chemistry class.
There are 66 objectives to be covered by upcoming chemists if they complete this two-chapter assignment. It encompasses all of the information needed to deal with covalent bonds and molecular geometry. Colorful diagrams display the molecular orbital structures. Charts are used to compare them. Practice problems and vocabulary definitions abound!
As amazing as James Bond is, the surface tension of water does not allow him to walk on it! In this series of little lab activities, physical scientists play with the properties of water due to the hydrogen bonds and resulting polarity. They float a paper clip on the surface, compare oil and water, experiment with evaporation, and think about why water expands as it freezes. Background information, materials, and a challenge are all provided. Lab groups should put together a report of what they learn.
At the top of the page are a reading passage and colorful diagram that depicts the tug-of-war that occurs between bonding molecules due to electronegativity. High school chemists fill in a chart with electronegativity values, the difference, and the type of bond formed as a result. This is a neat learning exercise, pertinent to any general chemistry curriculum.
In "The Nature of Covalent Bonding," chemistry hopefuls demonstrate an understanding of various types of covalent bonds, electron configuration, and resonance structures through fill in the blank, true or false, and matching questions. They complete the activity by drawing three electron dot structures of compounds.
