PPT-Covalent Compound Notes

Why do atoms bond Atoms gain stability when they share electrons and form covalent bonds Lower energy states make an atom more stable Gaining or losing electrons makes atoms more stable by forming ions with noblegas electron configurations. Covalent Compounds. Warmup. – write out the answer. Identify these compounds as covalent or ionic. SiO. 2 . is _____. FeS. 2 . is _____. cobalt(III) chlorate is _______. H. 2. O is _______. An ionic bond is____. Co = Together. The Octet Rule. The octet rule says that all atoms want to have eight valence electrons, like the noble gases.. One way that atoms can follow the octet rule is by giving and taking electrons… ionic bonding. Chapter 9 ~ most compounds, including those in living organisms, are covalently bonded. What You’ll Learn. I will analyze the nature of a covalent bond. I will name covalently bonded groups of atoms. Fancy word for naming and formulas. Rules. You did a lot of naming in grade 9, we will expand now. All elements have symbols. Metals on the left side. Non-metal on the right side. Separation is the stair-case. Covalent Bonding. Many compounds do not form ionic bonds. These compounds contain two or more non-metallic atoms. . For example, CO. 2. is made of two different non-metals, carbon and oxygen. These compounds are formed through the sharing of valence electrons. . Directions: Name these compounds. List if they are either ionic or covalent.. PBr. 3. Na. 2. SO. 4. CF. 4. Directions: Write the formula for the following compounds.. carbon monoxide. sulfur dichloride. Do Now: from last years regents. Chemical Formulas. Tell . type. & . number. atoms in compound. Microscopic level: . Formula gives atom ratios. Macroscopic level: . Formula gives mole ratios. EXAMPLE. Molecular Compounds: . Sharing Electrons. The names of molecular compounds need prefixes because several different compounds can be formed from the same two nonmetals. .. Learning Goal . Given the formula of a molecular compound, write its correct name; given the name of a molecular compound, write its formula.. Ionic bonds . result when electrons are transferred between atoms. Covalent bonds . result when valence electrons are shared between atoms. Types of Bonds. Formed between a . metal. and a . non-metal. Covalent Compounds. Formed between two non-metals. Valence electrons are shared between atoms. Binary Covalent Compounds. Contain just two different types of non-metal elements. Some Different Rules. STANDARD C: (CHAPTER 4) TYPES OF BONDING: Comparing and contrasting ionic, covalent and metallic bonding. Identifying the properties associated with each type of bond.. LG (a) Describe an ionic bond between atoms.. Matter takes many forms in nature. : In this chapter, we are going to learn to distinguish the type of compound that we have already studied, the “. ionic. . compound. ” (which contains oppositely-charged particles: metal . US SECURITIES AND EXCHANGE COMMISSION Plaintiff Civil Action No 20-CV-5205 v GEOFFREY J THOMPSON Defendant When elements combine to form compounds a chemical reaction occurs creating a new compound with properties that are different from the original elements.. When a new compound is formed it has a new chemical formula. A .
