2.1 Giant Ionic Structures Flashcards
0
Q
When do ionic compounds conduct electricity
A
When we met them or dissolve them in water
1
Q
What melting point do ionic compounds have
A
High
2
Q
Why do ionic solids have high melting points
A
They have giant structures with strong electrostatic forces that holds the ions together and a lot of energy is needed to overcome the forces
3
Q
When can ions move freely in an giant electronic structure
A
When melted/dissolved in water
4
Q
Why can ionic substances conduct electricity when molten or when dissolved in water
A
The ions can move freely and carry the charge
5
Q
Why can ionic compounds not conduct electricity when solid
A
Because the ions can are you vibrate about fixed positions they cannot move
