PPT-Covalent Nomenclature

Prefix System binary compounds 1 Less electronegative atom comes first Add prefixes to indicate of atoms Change the ending of the second element to ide M olecular Covalent Nomenclature. 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 noble-gas electron configurations.. 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. 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. 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. HIDE ALL. SHOW ALL. A. B. C. J. H. G. F. I. K. D. E. 2. Handcuffs Nomenclature. HIDE ALL. SHOW ALL. B. C. J. H. G. F. I. K. D. E.

Molecular Orbital!. Molecular Orbital- . The space that shared electrons move in. Covalent Bond- . when two atoms share electrons. Energy and Stability. Most atoms have low stability except noble gases. 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. Covalent bonds:. occur between two or more . nonmetals. ; electrons are . shared. not transferred (as in ionic bonds). The result of sharing electrons is that atoms attain a more stable electron configuration.. 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.
