C4b ionic bonding

HideShow resource information
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
