Activity 8: How Atoms Interact With Each Other Atoms Unite! Let’s Make a Bond Webquest Introduction A chemical bond form when atoms combine to form stable compounds and molecules. In this activity you will learn about different types of chemical bonds and how they are formed. You will also learn why some atoms bond with other atoms and why some do not bond. Complete the worksheet provided by your teacher as you learn about chemical bonding in this web quest. Log on to the following website: http://www.kn.att.com/wired/fil/pages/listchemicalwe.html
SECTION 1: Introduction to bonding What is a chemical bond?
Explain why do most atoms form chemical bonds?
SECTION 2: Types of Chemical Bonds Atoms can react with one another to form new substances called _________________________. In 1916, the American chemist Gilbert Newton Lewis proposed that chemical bonds are formed between atoms because ______________from the atoms interact with each other. He suggested that atoms with fewer than ____________________________bond together to share electrons and complete their __________________________________.
There are two main types of chemical bonding;____________ bonding and _____________bonding. What is an ionic bond?
How are ionic bonds formed?
Give one example of an ionic bond.
http://www.visionlearning.com/library/module_viewer.php?mid=54 This website explains the reaction between sodium and chlorine to produce sodium chloride. Read the information and (1) write a summary and (2) Sketch an illustration which show how sodium and chlorine bond with each other. SUMMARY:
ILLUSTRATION:
http://www.visionlearning.com/library/module_viewer.php?mid=55 Ionic compounds have many features in common. List FIVE features of ionic compounds. 12345(a) What is a covalent bond?
How are covalent bonds formed?
Give one example of a covalent bond.
http://www.visionlearning.com/library/flash_viewer.php?oid=1348&mid=55 Sketch and describe what you see. SKETCH:
Covalent molecules exist as true ___________________because electrons are _____________________in covalent molecules, no full ionic charges are formed. Covalent molecules are not strongly attracted to one another. As a result, covalent molecules move about freely and tend to exist as _____________ or ___________________at room temperature. Lewis dot structures are used to represent the ___________________of an atom. Lewis structures can also be used to show___________________ between atoms. Write the Lewis Dot structures for H2 and O2 below:
Both atoms in the H2 molecule have an equal attraction (or affinity) for _______________________. The bonding electrons are equally shared by the two atoms, and a __________________________is formed. Whenever two ___________________________of ________________________________is formed.

A polar bond is formed when electrons are _______________ shared between two atoms. In a polar covalent bond, the bonding electrons will spend a ______________amount of time around the atom that has the _________________affinity for electrons. List one example of a polar covalent bond.

SECTION 3: Properties of Molecular bonds http://www.chemguide.co.uk/atoms/structures/molecular.html The physical properties of substances vary with the type of intermolecular attractions. The intermolecular attractions are called hydrogen bonding or Van der Waal forces. Physical properties are governed by the ___________________forces. Molecular substances tend to be ____________, ___________ or low melting point _______________, because the intermolecular forces of attraction are comparatively weak. Most molecular substances are ___________________(or only very sparingly soluble) in water. Molecular substances are often soluble in ______________solvents. Organic solvents are also molecular – Like substances dissolve like substances. Molecular substances won't conduct_______________________.
SECTION 4: Application Choose one of the following to complete to demonstrate what you have learned. 1.STORY - Choose one type of bonding and write “A Day in the Life of an Atom” story describing what it's like to be an atom that forms your chosen bond type. The story should incorporate at least 5 properties of this type of bond. 2.COMIC STRIP - Choose one type of bonding and write a comic strip with 5+ frames. The comic should incorporate at least 5 properties of this type of bond. 3. SINGLE-FRAME CARTOON - Draw a single-frame cartoon for each type of bonding. Each cartoon should incorporate at least two key properties of each bond type.
