PPT-Covalent Bonding and Molecular Compounds

62 Molecules Molecules a neutral group of atoms held together by covalent bonds Molecular compound a cmpd whose simplest units are molecules Chemical formula indicates relative of atoms of each kind in a chemical compound by using atomic symbols amp subscripts. and . Electronegativity. Presented by . Leticia Bonita Prince. Newcastle University 4. th. Year . MChem. Student. Aims of Today. Increase your understanding of bonding and electronegativity. Increase your spatial skills and awareness using software designed by the CCDC. 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.. Introduction to Chemical Bonding. Introduction to Chemical Bonding. Objectives:. Define . chemical bond.. Explain why most atoms form chemical bonds.. Describe ionic and covalent bonding.. Explain why most chemical bonding is neither purely covalent nor purely ionic.. Elements with high electronegativities (non-metals) will not give up electrons. Bonds are not formed by a transfer of electrons, they are formed by sharing electrons.. Molecules are neutral groups of covalently bonded atoms. This topic will be investigated under five main headings:. Chemical Compounds. . Ionic Bonding. . Covalent Bonding. Electronegativity. . Shape of Molecules and Intermolecular forces. Chemical Compounds. . and Structure. IB Chemistry. Topic 4. . Bond - A force that holds . atoms . together and . makes . them . function as a . unit.. 4.1 Ionic Bonding.

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 . Covalent Compounds. Formed between two non-metals. Valence electrons are shared between atoms. Binary Covalent Compounds. Contain just two different types of non-metal elements. Some Different Rules.

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..
