Migration of Ions via Electrolysis. 3 of 17 Isoelectronic Ions Have the same electronic configuration and number of electrons. 4 of 17 Trend in Ionic Radius across a period Ionic radius decreases across a period. 5 of 17 Covalent bond is? The strong electrostatic attraction between the two nuclei and the shared pair of electrons between them. 6 of 17 Bond length distance between 2 nuclei of 2 atoms covalently bonded together. 7 of 17 Bond Enthalpy Enthalpy change when one mole of a bond in the gaseous state is broken. 8 of 17 electronegativity The ability of an atom to attract the bonding electrons in a covalent bond. 9 of 17 Trend in electronegativity up a group... Increases 10 of 17 Trend in electronegativity across a period... Increases 11 of 17 Greater the electronegativity difference in a covalent bond... the greater the % ionic character. 12 of 17 Polar Covalent Bond is? When the bonded atoms have different electro-negativities. 13 of 17 London Forces are? Attractive intermolecular forces between instantaneous dipoles and induced dipoles. 14 of 17 What is the process by which individual ions of an ionic compound become surrounded by water molecules and form electrostatic attractions? Hydration 15 of 17 Metallic Bonding Strong electrostatic forces of attraction between metal ions and the delocalised electrons. 16 of 17 Ionic Bonding Strong electrostatic forces of attraction between oppositely charged ions. 17 of 17
