Find Polar Bonds educational ideas and activities
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!
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!
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.
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 worksheet by drawing three electron dot structures of compounds.
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.
This is an online exercise in which chemistry learners answer a series of multiple choice questions about bonding. Topics addressed include ionic and covalent bonds, electronegativity, ions, valence electrons, resonance structure, and the octet rule. When learners submit, the correct answers get highlighted in green, and if they made errors, they are highlighted in red. This is a terrific way to study for an exam.
A more thorough PowerPoint on chemical bonds and chemical reactions would be hard to find! Through 108 slides, chemistry learners are taught about how compounds are formed, how to name them, and how to balance chemical equations. They are exposed to different types of bonds and reactions. You could show this in segments, stopping not only at the included "Check for Understanding" slides, but also to practice drawing molecular structures and balancing equations along the way.
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.
An organized table charting the different types of chemical bonds arrays this resource. The octet rule, ionization energy, and the naming of compounds are also reviewed. Young chemists answer review questions in multiple choice fashion. They can check their answers with those listed at the bottom of the page, making this a terrific pre-exam review.
Sal introduces students to the ways that atoms "stick together" by bonding. Students see that the process of atomic bonding is what creates molecules. He outlines specific examples of atoms combining through covalent bonding, polar covalent bonding, and metallic bonding. Previous knowledge of how electrons are given away and taken by elements would come in handy when viewing this presentation for the first time.
High school chemists chart the properties of different types of solids after considering their various intermolecular forces. They examine ionic and metallic bonding and draw electron dot structures for several different compounds. This worksheet is an ideal overview of these concepts and can be used as homework or an assessment.
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.
The different types of molecular interactions, and the impact they have on boiling, melting, and freezing points of different substances, is the focus of this chemistry video. Sal goes over Van Der Waal Forces, London Dispersion Forces, Dipole Attractions, and Hydrogen bonds in order to illustrate these points.
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 worksheet, pertinent to any general chemistry curriculum.
