Title: Giant covalent and simple molecular - some info.
Post by: borysek01 on November 01, 2011, 04:23:58 PM

Well, In my high school notes, I read that ionic bonds are giant structures.

1.Does that mean all the ionic bonds are giant covalent?
2.How do I know if an ionic or covalent bond is simple or giant?
3.What are the properties of those both structures (Giant&Simple)

"giant structure" merely means that it is a continuously repeating crystal structure, with no defined number of atoms

1. : Ionic bonds are NOT covalent. Simple ionic bonds that create crystal lattices are giant. Ionic bonds (with formal electron transfer) that form no such endlessly repeating lattice are not giant.

2. Read the definition; if a larger superstructure is created where you have a continuously repeating unit cell without being able to exactly pinpoint the number of atoms present, then it is giant.

3. try reasoning yourself on this one first. What would be the difference properties between a superstructure and a chaotic mixture
