3.4 Giant Ionic Structures Flashcards
1
Q
How are giant ionic structures held together
A
Because there are strong electrostatic forces operating in all directions and hold the oppositely charged ions together
2
Q
How much energy does it take to break up a giant ionic lattice
A
A lot because there are
3
Q
Do ionic compounds have high or low melting points
A
High
4
Q
Do ionic compounds dissolve in water
A
some, but not all
5
Q
What happens when an ionic compound dissolves in water
A
the lattice is split up by the water molecules, the ions are free to move in the solution, they can carry their charge to oppositely charged electrodes
6
Q
Can giant ionic structures conduct electricity
A
Yes, when molten or in a solution
7
Q
Can ionic solids conduct electricity
A
no
