PPT-Naming Binary Covalent Compounds

Covalent Compounds Formed between two nonmetals Valence electrons are shared between atoms Binary Covalent Compounds Contain just two different types of nonmetal elements Some Different Rules. Day 2. Working backwards: name to formula. It’s. . possible. . to. . determine. . a. . formula. . from. . a. . name. E.g. What is the formula of sodium oxide?. To get the answer, first write the valences:. 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____. Ch. . 16. Covalent Compounds. Covalent bonds. form when atoms share . their valence electrons. .. Covalent compounds. are formed from 2 or more nonmetals.. Rules for Naming Covalent Compounds. 1. Prefixes are used to show how many atoms of each element are present in the compound . What is the arrangement of the electrons around each chlorine atom in Cl. 2. ?. 2, 8, 8. This is the same as the electron configuration of an atom of which noble gas?. Argon. When atoms bond . covalently. 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. Including Naming. Note: We likely won’t make it to covalent nomenclature, this is the one students find FAR easier than ionic. Please refer to the videos and naming hand out for help with this, and as always office hours, discussions, and . COVALENT BOND. bond. formed by the . sharing . of . electrons . Covalent . Bonds. Between nonmetallic elements of similar electronegativity. .. Electronegativity = how badly an atom wants to add an electron (non metals have higher electronegativity). Bonding. Bonding models for methane, CH. 4. . Models are NOT reality. Each has its own strengths and limitations.. Ga . Standards. Students know . atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds.. Covalent bonding. Ionic bonding. Ionic Bonding. Bonding as you’ve never imagined it. http://www.youtube.com/watch?v=BCYrNU-7SfA. Objectives. To consider the features of ionic and covalent bonds, and the compounds they make. What do these images have in common?. How are they different?. What do you know about the uses of graphite and carbon?. Learning questions. What are giant covalent molecules?. How are they similar/ different from each other?. 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. Oxyanions. Oxyanions- negative ions containing oxygen.. These have the suffix “-ate” or “-ite”. “-ate” means it has more oxygen atoms bonded, “-ite” has less. For example. SO. 4. 2-. sulfate. Chapter 5: Molecules and Compounds. Learning Goals. Distinguish . between common and systematic names for compounds. . Name . binary ionic compounds containing a metal that forms only one type of ion.. 6.2. Molecules. Molecules – a neutral group of atoms held together by . covalent. bonds. Molecular compound – a . cmpd. whose simplest units are molecules. Chemical formula – indicates relative # of atoms of each kind in a chemical compound by using atomic symbols & subscripts.
