PPT-Ionic Bonding Lattice Energy

Michael Tian Koya Ionic Bonding Definition The complete transfer of valence electrons between atoms Its a type of chemical bond that creates two oppositely charged ions Typically an ionic bond happens between a metal and a nonmetal where the metal loses electrons to the nonmetal resulting in a cation and a anion. 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.. . 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. 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  . Including Naming. Note: We likely won’t make it to covalent nomenclature, this is the one students find FAR easier than ionic. Please refer to the videos and naming hand out for help with this, and as always office hours, discussions, and . Covalent bonding. Ionic bonding. Ionic Bonding. Bonding as you’ve never imagined it. http://www.youtube.com/watch?v=BCYrNU-7SfA. Objectives. To consider the features of ionic and covalent bonds, and the compounds they make. g. recall the stages involved in the formation of a solid ionic crystal from its elements and that this leads to a measured value for the lattice energy (students will not be expected to draw the full Born-Haber cycles). 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. SNC2D – Academic Science. Learning Goals. Use . Lewis dot diagrams to illustrate how a compound forms between a metal and a . non-metal.. Ions are formed when electrons are gained or lost. Where do electrons that are lost go?. Bonding Theories. Explain how atoms bond together to form molecules. Explain why some combinations are stable and others are not. Table salt . NaCl. …. Not NaCl. 2. Water is H. 2. O …. Not H. 3. 9.1 Bonding Models and AIDS Drugs. X RAY BEAM. ▽. △.

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 .
