PPT-Chemical Bonding and Molecular Structure

Presented by Anik Sinha Department of Chemistry SBSGovernment College Hili TYPES OF BONDS Ionic Bond Ionic bonds are thus electrostatic forces that bind together oppositely charged ions formed by the transfer of electrons from an electropositive element to an electronegative . 92B is applicable to bonding at services and in part states Bonding jumpers meeting the other requirements of this article Article 250 shall be used around concentric or eccentric knockouts that are punched or otherwise formed so as to impair the ele Metals. Look at the Periodic Table…. 75% of elements are metals!. Metals. They can vary a lot…. General Properties of Metals. Dense. Malleable. Ductile. Good conductors of heat and electricity. Shiny Lustre. Molecular Shapes. VSEPR Theory. From a correct Lewis structure, we can get to the 3-D shape using this theory.. VSEPR stands for . v. alence . s. hell . e. lectron . p. air . r. epulsion.. The theory is based on the idea that e- pairs want to get as far away from each other as possible!. This topic will be investigated under five main headings:. Chemical Compounds. . Ionic Bonding. .
