ionic/covalent solids

[osimsDDS]

hey quick question, can someone explain the difference between ionic and covalent solids and their properties...thanks a lot!!!

Also the face centered, body centered, and cant remember the last one...are those pertaining to ionic solids???

Also are why are metallic and ionic solids considered crystalline solids...thanks

Ok osims I can explain network covalent solid for you.Would that work for you?

Ok,first of all, I think we are mostly talking about carbon solid here when we are considering those cubes.Back to network covalent solid.There are 3 of them which are the most important ones,SiO2,C as grapghite,C as diamond.
NCS have very high melting points and are generally insoluble in most solvents.That is all I know so far...

Off the top of my head. Ionic solids are brittle, and have very high melting points, and cannot conduct electricity in the solid state. However, they will conduct electricity in the molton state. Ionic solids are held together very strongly.

Your second question. It goes "simple cube" to "body center" to "face center".

From what i kno, i think it goes like this....Ionic solids are basically anions and cations attracted to each other via electrical forces, and the forces act between ions not molecules and therefore they must be electrically neutral. as for covalent solids they are basically network solids. they are characterized by having VERY!! high melting points. Reason being, Intra molecular forces are much stronger then Inter molecular forces, and the bonding patterns will determine the properties of the network solid.

as for the second question, yes they are pertaining to ionic solids.

Crystalline solids are ones that exhibit highly regular repeating patterns, and due to the nature of ionic and metallic bonds, u are bound to have a recurring pattern, think of simple table salt NaCl for every Na there is a Cl the end product is neutral and if u have an equal amount of both and because, ever sodium will bond with another calcium, u wont have any irregular patterns.

hope this helps...im kinda rusty on my gchem...

plz correct me if im wrong 🙂
