Comments Posting comment... Premium member Presentation Transcript Ionic Bonding : Ionic Bonding Chemical Bond : Interaction between atoms or ions reduction in the potential energy of the system becomes more stable Involves valence electrons Chemical Bond Why Bond? : More stability Atoms want to achieve a lower energy state Why Bond? Ionic Bonding : Between a metal and a non-metal Metals lose electrons (cations) Non-metals gain electrons (anions) Ionic bond electrostatic attraction between the oppositely charged ions Atoms have large difference in electronegativity Ionic Bonding Simple cations : Group 1 metals lose 1 electron becoming +1 Ex: Li Li+ + e- Group 2 metals lose 2 electrons becoming +2 Ex: Mg Mg2+ + 2 e- Simple cations Simple anions : Group 17 non-metals gain 1 electron becoming -1 charge. Ex: F + e- F-1 Group 16 non-metals gain 2 electron’s becoming -2 charge. Ex: S + 2e- S-2 Simple anions Transition metals : Don’t follow group number Can form ions with different charges Ex: Iron can be Fe+2 or Fe+3 Charge is given in the form of Roman Numerals Transition metals Polyatomic Ions : Groups of atoms can join together Have overall electrical charge Form compounds with oppositely charged ions Ex: Carbonate (CO3-2) Polyatomic Ions Formula writing : Look up the charge of the metal ion (its positive) and combine it with the non-metal ion (its negative) The two must combine so that their addition is ZERO, compound must be neutral Ex: Na+ and Cl- become NaCl Formula writing Naming Ionic Compounds : Name the metal Name the non-metal (end in –ide) NaCl = sodium chloride Transition ions Include which charge is in the formula Use Roman Numerals Naming Ionic Compounds Formula Practice : Magnesium and Bromine Calcium and Oxygen Potassium and Phosphorous Iron (II) and Oxygen Iron (III) and Oxygen Calcium Phosphate Ammonium Carbonate Formula Practice You do not have the permission to view this presentation.
