PPT-Lewis Structures: non-octet breaking

BH 3 NH 3 Any common octet breaking atoms How many electrons are present What is the central atom Draw a skeletal structure Add electrons do you have enough to give all atoms octets. , let’s see what Lewis structure is. Lewis structure, also called electron-dot structure, is a structural formula in whicbetween two atoms represent a covalent bond. It was named from Gilbert New (Chp. 8,9). :.

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. Chemical bond. - attractive force between atoms or ions. Ionic bond . - electrostatic force between oppositely-charges ions; results from the transfer of electrons from a metal to a nonmetal.. Covalent bond . Chemical bond. - attractive force between atoms or ions. Ionic bond . - electrostatic force between oppositely-charges ions; results from the transfer of electrons from a metal to a nonmetal.. Covalent bond . Breaking the octet rule. Some compounds have atoms with more or less than 8 electrons around them (breaking the octet rule). There are 3 types. 1. odd numbered electrons. 2. electron deficient compounds. Bonding. Bonding models for methane, CH. 4. . Models are NOT reality. Each has its own strengths and limitations.. Ga . Standards. Students know . atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds.. 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 .
