Linguistics and the social. Ms. . Grobsky. Chemical Bonding. Bonding is the interplay between interactions between atoms. Energetically favored. Electrons on one atom interacting with protons of another atom. Energetically unfavorable. 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). Atoms, Orbitals & Bonding Topics:. Very quick history of chemistry…. What is organic chemistry?. Atomic models: nuclear to quantum. All . about . orbitals. How . orbitals fill: electron . configuration. Molecules and . Polyatomic Ions. A molecule is represented by a Lewis structure in which the valence electrons of all the atoms are arranged to give octets. .. Learning Goal . Draw the Lewis structures for molecular compounds or polyatomic ions.. Malcolm, Xavier, Genna. Octet Rule. -Small molecules and polyatomic ions can use basic octet rule.. -Larger molecules, determine general arrangement of atoms, skeleton.. -Always includes central atom, atoms surrounding it bonded.. Molecules and . Polyatomic Ions. A molecule is represented by a Lewis structure in which the valence electrons of all the atoms are arranged to give octets. .. Learning Goal . Draw the Lewis structures for molecular compounds or polyatomic ions.. 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 Bonding. A . chemical bond . is the force that holds two atoms together and makes them function as a unit. Atoms form bonds to become most stable and obtain an octet. Covalent Bonding: Electrons are shared between two or more elements. Always between 2 non-metals. Sigma Bonds. Sigma Bonds. s. bonds. Sketch (badly is fine) what the bonds in the following molecules look like according to valence bond theory:. H. 2. Cl. 2. HCl. s. bonds. Sketch (badly is fine) what the bonds in the following molecules look like according to valence bond theory:. 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..
