What structure do ionic compounds have?
Giant ionic lattice
2
New cards
What do the ions form?
A closely packed regular lattice arrangement with very strong electrostatic forces of attraction between oppositely charged ions, in all directions in the lattice.
3
New cards
What properties do ionic compounds have?
- High melting / boiling points (due to many strong bonds between the ions, takes lots of energy to overcome this)
4
New cards
- Solid = ions held in place , Melted = ions move freely (carry electric charge)
5
New cards
- Some ionic compounds also dissolve in water, the ions separate and are all free to move in the solution, so they'll carry electric charge
6
New cards
How to find the empirical formula in a dot and cross diagram?
Count up how many atoms there are of each element
7
New cards
