Bonding 0.0 / 5 ? ChemistryBonding & shapesASOCR Created by: nikolanowakCreated on: 21-04-14 13:57 Definition of ionic bonding? The electrostatic attraction between oppositely charged ions 1 of 16 Define giant ionic lattice A 3D structure of oppositely charged ions held together by strong ionic bonds 2 of 16 Define covalent bonding A shared pair of electrons 3 of 16 Define dative bonding? A shared pair of electrons where both electrons originate from one of the bonded atoms only. 4 of 16 What is the bond angle in tetrahedral? 109.5 5 of 16 What is the shape of a molecule with 107 degrees? Pyramidal, eg ammonia 6 of 16 a non linear molecule has what bond angle? 104.5 eg water 7 of 16 What shape has 120degree bond angles, and give an example Trigonal planar, eg boron trifluoride 8 of 16 An octahedral molecule has what bond angles? 90d e.g. SF6, sulfur hexafluoride 9 of 16 Trigonal bipyramidal shape has what bond angles? Give an example 90 degrees and 120 e.g PCl3, phosphor trichloride 10 of 16 What is electronegativity? The measure of the attraction of a bonded atom for the pair of electrons in the bond. 11 of 16 Define metallic bonding The electrostatic attraction between positively charged metal ions and delocalised electrons. 12 of 16 What is a giant metallic lattice? A 3D structure of positive ions and delocalised electrons, bonded together by strong metallic bonds. 13 of 16 What is a simple molecular lattice? 3D structure of molecules, held together by weaak Van der Waals forces. 14 of 16 What is a giant covalent structure? a 3d structure of atoms bonded together by strong covalent bonds, e.g graphite, diamond 15 of 16 What structure does NaCl have? Giant ionic lattice 16 of 16
