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 . VSEPR Theory, Polarity, and using . Electronegativity. Covalent . Bonds. Forms when 2 atoms share a pair of valence e. -. A. Types of Covalent Bonds. 1. . Single Covalent Bond . – two atoms share . 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. 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 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). i Nomenclature and othe r conventions EUR 24384 EN - 2010 ILCD Handbook : Nomenclature and other conve ntions First edition i The mission of the JRC - IES is to provide scientific - technical supp A.

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?. Mrs. Page. Essential Idea. Lewis (electron dot) structures show the electron domains in the valence shell and are used to predict molecular shape. .. Nature of Science. Scientists . use models as representatives of the real world – the development of the model of molecular shapes (VSEPR) to explain observable properties.. Covalent bonds . result from the . sharing . of electrons. between two atoms.. A covalent bond is a . two-electron bond . in which the bonding atoms share valence electrons.. A . molecule . is a discrete group of atoms held together by covalent bonds.. Aims. Dr. Habibur Rahman. Associate Professor. J. N. College, Boko. Botanical Nomenclature.

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.
