PPT-Covalent Bonds! Yeah!

Elements with high electronegativities nonmetals will not give up electrons Bonds are not formed by a transfer of electrons they are formed by sharing electrons Molecules are neutral groups of covalently bonded atoms. Molecular Geometry. Ch. 6 Sections 1-4 Review. In general, what determines whether atoms will form chemical bonds?. Atoms will form a chemical bond if their potential energy is lowered in doing so.. Describe the difference between ionic and covalent bonding.. 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. 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. 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). Valence Electrons and Bonding. The number of valence electrons (electrons in the outermost energy level) in an atom of an element determines many properties of that element, including the ways in which the atom can bond with other atoms.. Electron Pairs. Recall that in the Lewis/electron dot diagram, only valence electrons are shown. We consider the shell that they are in to be the valence shell. . These valence electrons give the element its chemical properties, and therefore determine its ability to form chemical bonds. . 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?. we shine the light of God. And when we speak, . we speak with words of love. And when we dance, . we may get a little wild. Cause we’re the people of God, yeah. The people of God, yeah. Yeah, we shine, . On Friday nights we’d meet in Joe’s back yard (Joe’s back yard).. We’d set off into town, singing “Knees Up Mother Brown”,. Then at our local Music Hall we’d all settle down. . And we’d sing along to each song, . 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.. SmartStarter. What is the octet rule?. SmartStarter. Draw the electron dot diagram for ionic compound MgCl. 2. Compare. – Eyes on Chemistry. Epsom Salts. Rock Salt. Sucrose. One more…. WHAT DO YOU NOTICE ABOUT THEIR STRUCTURE?. Diamond. Covalent bonding. Usually gases or liquids. Covalent bonds in the molecule are strong but forces between molecules (intermolecular) are weak. Low melting and boiling points.. Due. to having w. The Covalent Bond. Section 9.1. Worldwide, scientists are studying ways to increase food supplies, reduce pollution, and prevent disease. Understanding the chemistry of compounds that make up fertilizers, pollutants, and materials that carry genetic information is essential in developing new technologies in these areas. An understanding of the chemistry of compounds requires an understanding of their bonding..
