They perform practice questions on slide 12 where they decide if each pair of elements would form an ionic, non-polar covalent, or polar covalent bond. You must have 30 different compounds!!
After you reach 15, you will need to come up and get a new set When finished, you need to turn in your template and get a molecular naming review half sheet Metal Nonmetal Metal Ion NM Ion Cmpd. As students take notes there is an opportunity for students to perform practice questions.
I have students perform Periodic Table Aerobics. Students find covalent name MUCH easier than ionic, the only issue is remembering the proper prefixes. I allow them to use their notes and to work with their table partner if need be.
I have them perform aerobics to ensure that they recall the components metals, nonmetals, or both for Ionic, Covalent, and Metallic bonds. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
Within this lesson the only resource needed is whiteboards, dry-erase markers, and erasers for the covalent naming whiteboard practice. The only difference is that when you have more than one of a Specific polyatomic ion in a formula you must encase it in parenthesis.
I have students do an Ionic Compound Quick Review to help reinforce what we have already learned about ionic compounds. Ionic Ionic bonding occurs between a metal and a nonmetal. Covalent Covalent bonding occurs when two nonmetals share electrons to fill their valence energy level.
They also perform practice questions on slides 16 and 17 for covalent naming.
Treat polyatomic ions as you would an ion — crisscross to determine the formula. Use your reference sheets to determine the name of the following polyatomics. Students have already learned the basics of covalent bonds through the introductory lessons of Bonding Inquiry and Ionic, Covalent, and Metallic Bonds.
Which elements are involve d in ionic compounds? This is tricky and I have them try to solve the problems through both using the electronegativity values and by looking at the location of the elements on the periodic table I just remind them that Hydrogen has the same electronegativity value as Phosphorous.
I go over the answers with students using the answer key. Always use prefixes in the names. Developing and using models Introduction In this lesson students delve into covalent bonding through taking notes and practicing with whiteboards and individual practice.
Nonmetals gain enough electrons to fill their valence level and become anions. Which elements are involved in covalent compounds? I give students about 5 minutes to work on the paper. You can only reduce subscripts outside the parenthesis. Developing and using models because students learn to model the formation of covalent and metallic compounds.
Must use prefixes in the name. Metals lose all their valence electrons and become cations. WarmUp What is necessary to write ionic compounds? Name tells you the formula. When writing names for covalent compounds what must be included?
Ions form a crystalline lattice. Atoms combine to form individual molecules. Always crisscross oxidation numbers and reduce to determine the formulas of ionic compounds Do not use prefixes in the names.
Engage Building on prior knowledge In this section of the lesson I engage students in the topic in two ways. Covalent compounds form individual molecules that are not connected to each other. Metal is listed first, followed by the nonmetal. They behave as if they were one-atom ion.
Never use oxidation numbers to determine the formula. Drop the positive and negative signs Crisscross the superscripts so they become subscripts. Ionic Quick Review Explain 60 minutes In this section of the lesson I discuss metallic bonding slide 2covalent bonding slideshow electronegativity differences dictate bond type slidesand how to name covalent bonds slides Naming binary covalent compounds Table on p.
gives the prefixes used in naming covalent compounds. The first element named is usually the first one written in the formula-the least electronegative element The root word is the name of the element.
The first thing students do to practice naming covalent compounds is doing Partner Whiteboards. I periodically remind them to switch partners in terms of who is doing the writing throughout the whiteboard session. Covalent Naming Worksheet.

Name the first non-metal. that for naming a covalent compound, so before a compound can be named, it must be classified as ionic or covalent. Writing Formulas for Covalent Compounds The names of covalent compounds contain prefixes that indicate Microsoft PowerPoint - Naming Chemical Compounds A Review [Read-Only] Author: Jason.
Covalent Compound Naming Worksheet 1 ultimedescente.com Naming Covalent Compounds Solutions Write the formulas for the following covalent compounds: 1) antimony tribromide SbBr3 2) hexaboron silicide B6Si 3) chlorine dioxide ClO2 4) hydrogen iodide HI 5) iodine pentafluoride IF5.
Writing and Naming Compounds. Writing Compounds.
To write a formula for a compound, you need information You need to know the elements involved You need to know the number of electrons they lose, share, or gain to become stable.Download
