33 Covalent Bonding Worksheet Answers
Define covalent bond. Illustrate covalent bond formation with Lewis electron dot diagrams. Ionic bonding typically occurs when it is easy for one atom to lose one or more electrons and another atom to gain one or more electrons. Yet they still participate in compound formation. There is another mechanism for obtaining a complete valence shell: sharing electrons. When electrons are shared between two atoms, they make a bond called a covalent bond. Let us illustrate a covalent bond by using H atoms, with the understanding that H atoms need only two electrons to fill the 1s subshell. This explains why hydrogen is one of the diatomic elements. As another example, consider fluorine. F atoms have seven electrons in their valence shell: These two atoms can do the same thing that the H atoms did; they share their unpaired electrons to make a covalent bond.

Modern Chemistry Chapter 8 Test Answers
Note that each F atom has a complete octet around it now: We can also write this using a dash to represent the shared electron pair: There are two different types of electrons in the fluorine diatomic molecule. The bonding electron pair makes the covalent bond. Each F atom has three other pairs of electrons that do not participate in the bonding; they are called lone electron pairs. Each F atom has one bonding pair and three lone pairs of electrons. Covalent bonds can be made between different elements as well. One example is HF. Each atom starts out with an odd number of electrons in its valence shell: The two atoms can share their unpaired electrons to make a covalent bond: We note that the H atom has a full valence shell with two electrons, while the F atom has a complete octet of electrons.

Covalent Bond Practice Worksheet Answer Key
Use Lewis electron dot diagrams to illustrate the covalent bond formation in HBr. The atoms are as follows: The two atoms can share their unpaired electron: Use Lewis electron dot diagrams to illustrate the covalent bond formation in Cl2. Answer More than two atoms can participate in covalent bonding, although any given covalent bond will be between two atoms only. However, the O atom has only seven electrons around it, which is not a complete octet. We fix this by including a second H atom, whose single electron will make a second covalent bond with the O atom: It does not matter on what side the second H atom is positioned.

Chemical Bonding Worksheet Answer Key
Now the O atom has a complete octet around it, and each H atom has two electrons, filling its valence shell. This is how a water molecule, H2O, is made. Use a Lewis electron dot diagram to show the covalent bonding in NH3. Solution The N atom has the following Lewis electron dot diagram: It has three unpaired electrons, each of which can make a covalent bond by sharing electrons with an H atom. Answer There is a simple set of steps for determining the Lewis electron dot diagram of a simple molecule. First, you must identify the central atom and the surrounding atoms. The central atom is the atom in the center of the molecule, while the surrounding atoms are the atoms making bonds to the central atom. The central atom is usually written first in the formula of the compound H2O is the notable exception.

After the central and surrounding atoms have been identified, follow these steps: Count the total number of valence electrons. Add extra if the species has negative charges and remove some for every positive charge on the species. Write the central atom and surround it with the surrounding atoms. Put a pair of electrons between the central atom and each surrounding atom. Complete the octets around the surrounding atoms except for H. Put remaining electrons, if any, around the central atom. Check that every atom has a full valence shell. The B atom is the central atom, and the F atoms are the surrounding atoms. There is a negative sign on the species, so we have an extra electron to consider. Count the total number of electrons. Write the central atom surrounded by surrounding atoms. There are no additional electrons to add to the central atom. The B atom has eight electrons around it, as does each F atom.

Each atom has a complete octet. If we were to follow these steps for the compound formaldehyde CH2O , we would get the following: The H and O atoms have the proper number of electrons, but the C atom has only six electrons around it, not the eight electrons for an octet. How do we fix this? We fix this by recognizing that two atoms can share more than one pair of electrons. In the case of CH2O, the O and C atoms share two pairs of electrons, with the following Lewis electron dot diagram as a result: By circling the electrons around each atom, we can now see that the O and C atoms have octets, while each H atom has two electrons: Each valence shell is full, so this is an acceptable Lewis electron dot diagram. If we were to use lines to represent the bonds, we would use two lines between the C and O atoms: The bond between the C and O atoms is a double bond and represents two bonding pairs of electrons between the atoms. What is the proper Lewis electron dot diagram for CO2?

Chapter 10 Chemical Quantities Practice Problems Answers With Work
Solution The central atom is a C atom, with O atoms as surrounding atoms. Following the rules for Lewis electron dot diagrams for compounds gives us The O atoms have complete octets around them, but the C atom has only four electrons around it. The way to solve this dilemma is to make a double bond between carbon and each O atom: Each O atom still has eight electrons around it, but now the C atom also has a complete octet. This is an acceptable Lewis electron dot diagram for CO2. Answer It is also possible to have a triple bond, in which there are three pairs of electrons between two atoms. Good examples of this are elemental nitrogen N2 and acetylene C2H2 :.
