Giant Ionic Structures Have High Melting and Boiling Points Flashcards
What do compounds with ionic bonding always have?
Giant ionic structures
How are the ions held together?
In a closely packed 3D lattice arrangement by the attraction between oppositely charged ions
Why is the electrostatic attraction between oppositely charged ions very strong?
a lot of energy is needed to overcome the strong attraction, this means that ionic compounds have high melting and boiling points
What also affects the strength of ionic bonding?
The charges on the ions
Which will be held together by stronger forces of attraction, a lattice of 2+ 2- ions or 1+ 1- ions?
2+ And 2- ions
Lattices made up of higher charge ions will have…
Higher melting and boiling points
