PPT-COVALENT BONDING 1 Chemical Bond

A Quick Review A bond results from the attraction of nuclei for electrons All atoms are trying to achieve a stable octet IN OTHER WORDS the protons in one nucleus are attracted to the electrons . 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.. 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. This topic will be investigated under five main headings:. Chemical Compounds. . Ionic Bonding. . Covalent Bonding. Electronegativity. . Shape of Molecules and Intermolecular forces. Chemical Compounds. There are two kinds of pure substances. Elements. Compounds. Let’s start the new notes….

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. Types of Chemical Bonds.
