Ionic compounds Flashcards
1
Q
ionic compounds general information
A
•between a metal and non-metal
•giant ionic lattice
•strong electrostatic forces of attraction between oppositely charged ions
2
Q
Why do ionic compounds have a high melting and boiling point?
A
•giant ionic lattice
•strong electrostatic forces of attraction between oppositely charged ions
•lots of energy needed to overcome
3
Q
Can ionic compounds conduct electricity as a solid?
A
•no the ions are in fixed positions so cant move
4
Q
When can ionic compounds conduct electricity?
A
•When molten (melted) or aqueous (dissolved in water)
•ions are free to move and carry a charge (current)
