PPT-Ionic and covalent bonding

Covalent bonding Ionic bonding Ionic Bonding Bonding as youve never imagined it httpwwwyoutubecomwatchvBCYrNU7SfA Objectives To consider the features of ionic and covalent bonds and the compounds they make. . Ionic (Atomic) Radii & Coordination Number (CN). Ionic radius: . Hypothetical radius (size) of an ion (. cation. or anion). Calculated values from the bonding distances. CN. Number of one kind of the bond forming ions (atoms) surrounding the other, which are forming the first direct 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. 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.. Ball-and-stick model. Molecular . Compounds. OBJECTIVES:. Distinguish. between the melting points and boiling points of . molecular. compounds and . ionic. compounds.. Molecular . Compounds. OBJECTIVES:. Higher Supported Study - Week 2 . Key Areas – Periodic Trends . The trends in . covalent radius . across periods and down groups.. The trends in . ionisation energies . across periods and down groups. . Bonding Discussion. Bonding. . Ionic. . Covalent. . Metallic. Determined by difference in Electronegativity between atoms.. Ionic . Compounds. Crystalline . solids (made of ions) . High melting and boiling points . Types of bonds. Ionic bonding. results from electrostatic attractions among ions, which are formed by the . transfer. of one or more electrons from one atom to another.. Covalent bonding. results from . Electrons are transferred from an atom of low electronegativity to one of high electronegativity. Anion (-) and cation ( ) formed. Opposite charges attract – called an . electrostatic force. Formula Unit. Day . 6. – Venn Diagram, . haber. Process. Metallic . Bonding, Properties of Substances reading, . Warm up. ON PAGE 23. What do ionic and covalent bonding have in common? What is different?. Time: . Reading. for Tuesday 8/31: Chapter 2 section 5 and Chapter 3 section 1. Homework. WS. 2. : due Tuesday 8/31 (8:00 AM) . WS. 3. : due Thursday 9/2 (8:00 AM). Lab. . Today: . EXP 2 – Nomenclature. Section 9.1 – Bonding of Atoms. Ionic and Covalent Bonds. Ionic. : Conduct electricity, high MP, high BP, dissolve in water.  . Covalent. : Do not conduct electricity, low MP, low BP, do not dissolve in water. Ionic bonds form a . giant lattice structure. Sodium chloride is an ionic compound formed by the reaction between the metal sodium and the non-metal chlorine.. During the reaction, one electron is transferred from each sodium atom to each chlorine atom.. 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..
