Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. Fill in the blank: I discuss my philosophy about homework further in my lesson reflection. Remind students to complete each sample problem with these steps: Negatively charged ions are called anions.
Argon has a total of 8 electrons bolded in redwhich satisfies the Octet Rule. Included in every 5E lesson is a homework assignment, assessment, and modified assessment. This is followed by showing oxygen bonding to another oxygen with a double bond with two bonding pairs of electrons.
We will examine how atoms share electrons to form these bonds, and we will begin to explore how the resulting compounds, such as cholesterol, are different from ionic compounds. Throughout the process, task cards will continue to assist students to understand the differences between ionic and covalent bonds.
At this station, students will be watching a nine-minute video explaining the differences between covalent and ionic bonding. The atom with the higher electronegativity will have a stronger pull for electrons Similiar to a Tug-O-War game, whoever is stronger usually wins. Since each Oxygen atom has 3 lone pairs of electrons, they can each share 1 pair of electrons with Carbon; as a result, filling Carbon's outer valence shell Satisfying the Octet Rule.
This type of bond is much stronger than a single bond, but less stable; this is due to its greater amount of reactivity compared to a single bond. Compounds can be very complex combinations of atoms, but many important compounds are fairly simple. Explain to students they will be taking notes during the video.
Hit Or Miss Mastery. To satisfy the Octet Rule, each atom gives out 1 electron to share with each other; thus making a single bond.
Charged atoms are called ions. Second, instead of having a circle around the chemical symbol to represent the electron shell, they have up to eight dots around the symbol; each dot represents a valence electron.
Note the convention of first writing the number and then the sign on a multiply-charged ion. Class Activity Write these words on the board: On the left, a chlorine atom has 17 electrons.
I use one during this lesson because showing them how electrons can be shared through a frame by frame slide breakdown helps them visualize the process.
The types of covalent bonds can be distingished by looking at the Lewis dot structure of the molecule. I have students perform Periodic Table Aerobics. Students will be demonstrating the bonds of H2O and NaCl. Each Oxygen atom has 6 valence electrons whereas the Carbon atom only has 4 valence electrons.
Larger molecules are constructed in a similar fashion, with some atoms participating in more than one covalent bond. Charges of Monoatomic Ions. Table salt, as we have seen, consists of only two elements: Although it is said that atoms share electrons when they form covalent bonds, they do not usually share the electrons equally.
Developing and using models Introduction In this lesson students delve into covalent bonding through taking notes and practicing with whiteboards and individual practice. For the main group elements, the number of valence electrons is the same as the group number listed at the top of the periodic table.
Water- needed for life Give an example of a metallic bond and name a use of it. What type of bonds are shown in the pictures.
In contrast, when two hydrogen atoms get close enough together to share their electrons, they can be represented as follows:.
Covalent Bonds. Choose a substance, and then move electrons between atoms to form covalent bonds and build molecules. Observe the orbits of shared electrons in single, double, and triple covalent bonds. Chapter 3 – Ionic and Covalent Bonding This content can also be downloaded as a PDF file.

Throughout the process, task cards will continue to assist students to understand the differences between ionic and covalent bonds. WATCH IT! At this station, students will be watching a nine-minute video explaining the differences between covalent and ionic bonding.
Students will then. Summary. In this simulation, students investigate both ionic and covalent bonding. Students will have the opportunity to interact with many possible combinations of atoms and will be tasked with determining the type of bond and the .A student covalent bonding
