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!
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.
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.
This nifty little presentation uses computer animation to illuminate how ionic molecular bonds and covalent bonds are formed. This would be a terrific addition to your PowerPoint or Smart Board lesson on molecular bonding.
On this note-taking sheeet, chemistry learners list elements as metals or non-metals. They differentiate between ionic and covalent bonds. They draw Lewis structures for both types of bonds. This would be a terrific teaching tool when introducing ionic and covalent bonds.
An extensive resource for chemistry, this series of exercises and accompanying information could be used as review or added curriculum. Have your class read the information and complete the exercises for homework, or in class. Your choice! The resource covers compounds, ionic and covalent bonds, ionic formulas, atomic mass, molar mass, and more. Take a look and see what this has to offer!
Flowing coherently, this slide show will take your chemistry aces from understanding simple covalent bonds, to naming binary and ternary compounds. Direct instruction and practice problems make this a complete lesson. Show these slides as a support to your lecture and then assign more practice problems as homework.
Prepare a time lapse video of fruit candies acting as atoms moving toward each other to form ionic or covalent bonds. After showing it as a demonstration, have lab groups work together to create a similar video. Over the time period suggested, the concpts of sharing, losing, or gaining electrons is reinforced.
First, high school chemists fill in a chart for seven elements to show the numbers of protons, electrons, valence electrons, and electrons needed to full the outer shell. Then combinations of elements are listed. Instructions say simply to follow the teacher's instructions, which could be to draw Lewis dot diagrams for each covalent bonding situation.
After a short introduction, chemistry aces get right into drawing electron dot diagrams for covalent bonds. There are only three questions to answer, so this is not a comprehensive activity. It can be used when introducing your class to covalent bonds.
Using the chemicals that leaked in the Bhopal gas tragedy of 1984, chemists examine covalent bonds. Provide for them the chemical reactions and have them draw Lewis diagrams for the molecules involved. That's about all there is to the instructional activity.
There are only six short answer questions on this assignment. Chemists explain electrical conduction properties of salt, salt water, and gold. They compare ionic and covalent bonds. The explain bond strengths. Perhaps you could use this as a pop quiz.
After studying the different aspects of atoms and their reactivity, pupils will find this summary PowerPoint useful for review. Some of the slides are informative with labeled diagrams; others give important vocabulary. Teachers may want to take sections of this slide show to use as a supplement to other chemistry lessons.
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.
If you've ever wondered why crystals are so strong and hard, Sal does a fine job of explaining, in chemistry terms, why this is so. Crystals are great examples of covalent networks; which are the strongest and hardest substances in the chemical world. Boiling points and the strength of covalent bonds are used to illustrate how weak or strong a chemical bond is.
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.
In this bonding worksheet, students read about the two different types of chemical bonding: ionic and covalent bonds. Students review ion notation and oxidation numbers. This worksheet has 24 fill in the blank, 2 drawings, and 4 short answer questions.
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!
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.
Page one of this resource displays a chart of five different types of solids: metallic, ionic, covalent, molecular, and atomic. The forces that hold the particles together are also described. On page two, junior chemists consider different compounds and determine what type of crystals they form, name predominant molecular forces, and compare boiling points. Answers are included at the bottom of the page, therefore this is best used as a review of concepts.
