Summary of Structures 0.0 / 5 ? ChemistryAtoms and compoundsGCSEAQA Created by: asho glenoCreated on: 14-04-15 16:21 Description of Structure - SM: Atoms are held together in each moleculeby strong... intramolecular forces and have weak intermolecular forces 1 of 13 I: All ionic compounds are giant, meaning millions of oppositely charged ions that... attract which creates strong electrostatic forces in all directions 2 of 13 They don't have intra and inter as it... isn't a molecu;e 3 of 13 GC: Large number of atoms that are in... layers e.g. bucky balls 4 of 13 Types of Bonding - SM: Electrons are shared in... a covalent bond 5 of 13 I: Electrons are lost or gained in ionic bonding between a... metal and a non-metal (metal gives electrons to non-metal) 6 of 13 GC: In covalent bonding between... non-metals 7 of 13 Melting + Boiling Points - SM: Low as not much heat energy is needed to... break weak intermolecular forces 8 of 13 I: High as a lot of heat energy neede to break... strong ionic bonds 9 of 13 GC: High as a lot of energy needed to break... strong covalent bonds 10 of 13 Conducting Electricity - SM: Can't when solid as no free electrons but... yes when dissolved and molten because the ions are free to move and carry charge 11 of 13 I: Can't when solid because there are no free ions but... yes when dissolved and molten as the ions are free to move and carry charge 12 of 13 GC: Generally can't but some can like... graphite which has delocalised electrons to carry charge 13 of 13
