PPT-Ionic Bonding Formation of Bond

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. 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. 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.. 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. ATOMIC STRUCTURE AND INTERATOMIC BONDING. Session II. Ionic bond – . metal. + nonmetal. donates accepts. electrons electrons.  . Dissimilar electronegativities  . 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.. 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.
