- a giant ionic lattice is many oppositely charged ions in a regular arrangement, and repeaten many times

what are giant covalent structures
- a giant covalent structure is many non metal atoms joined to other atoms by covalent bonds, these are arranged inyo a giant lattice structure because of the many bonds involved
2 of 5
why does magnesium oxide have a high melting point?
because it has a large number of charges, so they form stronger ionic bonds.
3 of 5
does sodium chloride conduct electricity?
only when it is melted or dissolved - ionic compounds can only conduct electricity if their ions are free to move
4 of 5
why is the melting point of sodium chloride high?
bcause of the strong electrostatic attraction between negative and positive ions
