C4b ionic bonding 0.0 / 5 ? ChemistryAtomsGCSEOCR Created by: WiktoriaGrudzinskaCreated on: 29-12-15 21:43 how can atoms achieve a 'stable' electronic structure ? by losing or gaining electrons to make a full outershell 1 of 8 explain which type of ion metal metal atoms form and why ? magnesium- as it has too much electrons 2 of 8 explain which type of ion non-metal atoms form and why ? oxygen- as it hasn't got enough electrons 3 of 8 what is ionic bonding? when atom loses electrons and become more positive forming a chemical bond between two ions of positive charge 4 of 8 what condition does sodium chloride require to conduct electricity ? it has to be melted 5 of 8 when can sodium chloride conduct electricity? A) solid B) molten C) dissolved in a solution ? C) dissolved in a solution 6 of 8 using the structure why does sodium chloride have a high melting point? because the ions form a large lattice structure that needs a lot of energy to break down 7 of 8 why is the melting point of sodium chloride lower than the melting point of magnesium oxide ? as magnesium oxide forms ions and it also forms a large lattice structure which need even more energy to break down 8 of 8
