Review of Chemical Bonding
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.
8.4 Section Review ~ Polar Bonds and Molecules
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!
Chemistry students review the trends found in the organization of the periodic table by completing this worksheet. They determine which of the given atoms has the largest ionic radius and which is the most electronegative. This worksheet has 6 matching, 4 true or false, 10 fill in the blank, and 2 problems to solve. It is neatly formatted and pertinent to any general chemistry curriculum.
For this electronegativity worksheet, students complete a chart given 10 molecules. They draw their Lewis structures, they draw the shape of the molecule, they determine the difference in electronegativity between the bonds, they determine the polarity of the bonds, they determine the symmetry of the molecule and they determine the polarity of the molecule.
12.1-12.3 Worksheet ~ Electronegativity and Chemical Bonding
Most of the 10 short answer questions on this chemistry handout have to do with electronegativity. There are also few that deal with types of bonds that form. Use this as a homework assignment or quiz.
Electronegativity and Bonding Worksheet
Learners are instructed to consider electronegativities of certain elements to determine their bonding type. Three examples are given to frame the activity, and 17 questions follow.
WS 3.6 Polar Bonds and Electronegativity
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.
Electronegativities of Elements
In this elements worksheet, students use a table showing the electronegativity values of elements to characterize compounds as ionic or covalent. This worksheet has 14 fill in the blank questions.
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.
All different types of bonding are covered in this PowerPoint, along with details of resulting bond and molecule shapes. The definitions of traditional molecule shapes and characteristics of behavior are very useful to assist in understanding polarity, electronegativity, and intermolecular attraction. The slides are quite text-rich, but the summaries are useful and would help in note taking.
Chapter 3: Chemical Compounds
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!
Other Periodic Table Trends
Ionization energy is the focus of this science video. Specifically, it covers 2nd Ionization Energy of the elements. Electronegativity is a key concept when trying to understand 2nd Ionization energy. Sal also discusses the metallic nature of an element - which affects 2nd Ionization energy as well.
Introduction to Oxidation States
Oxidation states in elements is the focus of this chemistry video. Sal illustrates how when an element loses electrons, it is moving toward a state of oxidation, and when an element is gaining electrons, it is moving toward a state of reduction - because electrons are negatively-charged.
Compounds and Their Bonds
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.
More on Oxidation States
In the previous video, Sal presented how elements move toward a state of oxidation (by losing electrons), and a state of reduction (by gaining electrons). This lecture takes that concept a bit further, and he provides more examples.
How Do Atoms Stick Together?
In this chemical bonding instructional activity, students answer 76 questions about compounds, Lewis dot structures, intermolecular forces between atoms, electronegativity and bonding and types of bonds.
What's in that Pill? Chromatography Lab
Learners study the difference between a mixture and a compound. They review filtration and distillation and then explore chromatographic separation. They complete an experiment in which they use chromatography to identify the active ingredients in over-the-counter analgesics.
Chalkboard Challenge: The Periodic Table and Periodicity
In a well-prepared Jeopardy-style game, your chemisty class can review the periodic table. Questions cover the element groups, some history, atomic number, atomic and ionic radii, electronegativity, and the shielding effect. What a fun way to prepare for a quiz or exam!
States of Matter
The three states of matter are the focus of this chemistry video. Sal uses the example of a water molecule, and explains in great detail what forces are present to make that molecule change back and forth between a liquid, a solid, and a gas. Of course, the temperature that the molecule is exposed to is the most important factor, but the molecular changes that take place are what he really goes into here.
Your young chemists will find these slides very informative. Groups and periods of the periodic table are labeled and described according to the charge. Comprehensive explanations of physical and chemical properties and how they relate to the atomic and stability will help with understanding chemical bonds. Also, practice naming compounds is provided. Though not flashy, this is a fact-filled and useful resource.
