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 . 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. 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 . CHEMICAL NOMENCLATURE. Writing Formulas. Binary ionic compounds. Ternary ionic compounds. Binary molecular compounds. Acids. Ionic Compounds. Composed of oppositely charged ions. Positive ion is a . cation.  . 1) . SeF. 6. . . ________________________________________.  . 2) . TeO. 3 . . ________________________________________.  . 3) . H. 2. O. . . ________________________________________.  . Ionic Bonding and Writing Formulas. Common Anion Name Changes. Nitr. ogen .  . Phosph. orus .  . Ox. ygen .  . Sulf. ur .  . Selen. ium .  . Fluor. ine .  . Chlor. ine .  . Brom. 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. Steps:. 1.) . Cation. is written before anion.. 2.) Charges must cancel. (ionic compounds are neutral). 3.) Atoms must be in smallest whole number ratio.. Write the formula units for the following ionic compounds: 1.) lithium chloride, 2.) strontium oxide, 3.) ammonium phosphate.. 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. I. onic compounds form between a metal and a nonmetal.. The metal forms a . cation. (+ ion) and the nonmetal forms an anion (-ion).. The . cation. is always named first and is the element name.. The anion is always named second – the root of the element name with an –ide ending.. 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..
