Ionic Compounds Flashcards
1
Q
Ionic compounds have a structure called a giant ionic _______.
A
Lattice
2
Q
The ions form a closely packed regular lattice arrangement and there is a very strong _____________ force of attraction between __________ charged ions, in all directions in the lattice.
A
- Electrostatic
2. Oppositely
3
Q
A single crystal of sodium ________ (table salt) is one giant ionic lattice.
A
Chloride
4
Q
What are the similarities of ionic compounds?
A
- High melting and boiling points.
- When solid, can’t conduct electricity.
- Only conduct electricity when ionic compounds melt.
- Some dissolve in water.
5
Q
Why do ionic compounds have high melting and boiling points?
A
Due to the many strong bonds between the ions.
6
Q
Why can ionic compounds only conduct electricity when melted?
A
When ionic compounds melt, the ions are free to move in the solution, so they can an electric current.
