chemistry f321 ocr bonding good luck! 3.0 / 5 based on 1 rating ? ChemistryBonding & shapesASOCR Created by: AaliyahCreated on: 19-05-13 17:23 what three types of bonding are there? covalent, Ionic and metallic 1 of 10 define the term ionic bonding the electrostatic attraction between oppositely charged ions 2 of 10 what is a dative covalent bond/coordinate bond? a shared pair of electrons which has been provided by one bonding atom only 3 of 10 Do giant ionic compounds conduct electricity when solid or molten? molten because the ions are free to move 4 of 10 what three types of intermolecular forces are there? van Der Waals, dipole-dipole and hydrogen bonds 5 of 10 Why does water have a high boiling point? strength of hydrogen bonds require a lot of energy to break 6 of 10 Define the term electronegativity a measure of the attraction of a bonded atom for the pair of electrons in a covalent bond 7 of 10 why do non-metals make covalent bonds? In order to acheive a full outer shell of electrons 8 of 10 why do metals have a high melting/boiling point? strong electrostatic attraction between positive ion and delocalised electron which require a lot of energy to break the attraction 9 of 10 Why do van der waal forces arise? at any point there may be an uneven distriibution of electrons inducing a dipole in nearby molecules. 10 of 10
