Station 1 Why is a chemical structure like a blueprint of a house?

Station 1 structural formula of water and a blue print of a house

Station 2: List four ways a chemical formula can be expressed? Lewis dot structures  Ball and stick models   Space fill models Structural Formula

Station 3 1 What is a bond length ? 2 What is bond angle? 3 Which model would we find these two things?

Station 4 Bond length Draw the ball and stick model for water. Label the bond length and the bond angle. Use red for oxygen and blue for hydrogen Bond angle

Station 5 Draw the space filled model for water Station 5 Draw the space filled model for water. Label the molecules and color red for oxygen and blue for hydrogen

Station 6: What is an isomer and what kind of chemistry is it important for? Each of the above is an isomer. What element is in the center of each?

Station 7 1. Even though chemist use a solid bar to show a bond, bonds are more like a ____________. Bonds can_________,_____________ and__________ with out breaking.

Station 8 Copy the picture and label the hydrogen bonds between the water molecules. What ends are attracted to each other?

Station 9 Lewis Dot Diagram Single line represents single bond and two lines represent a double bond. Each line is worth two electrons, count the number of electrons around the N. What do you think the negative means for the oxygen ( gain lose or share electrons). Look up the octet rule on your phone and give the definition.

Station 10 Why do atoms form bonds Station 10 Why do atoms form bonds? How many electrons are needed to be stable in the outer most shell?

Station 11 What are the two basic kinds of chemical bonds?

Station 12 What happens to the valence electrons in ionic compound Station 12 What happens to the valence electrons in ionic compound? Will they have a charge? If yes, give the name if gaining electron, give name if losing electron.

Station 13 What happens to the electrons in a covalent bond Station 13 What happens to the electrons in a covalent bond? Will they have a charge?

Station 14 What ways in which multiplication can be represented in a problem? Just in the way that many different ways to express the same thing so in chemistry we have many ways to represent a chemical formula. For each model of a formula match the correct name to picture.
