Ionic Solids

023 - Ionic Solids

In this video Paul Andersen explains how ionic solids form a lattice between cations and anions. According the Coulomb's Law the lattice energy increases as the ions carry a larger charge and are smaller. Some of the properties of ionic solids are high melting point, low vapor pressure, brittleness and the inability to conduct electricity. Ionic compounds can be readily dissolved by polar molecules like water.

I'm in general chemistry at a county college and your videos have helped me more than my professor has all semester. You're a life savor!

[rosebell]

you are the best you have helped me in biology first semester and now you are helping me in chemistry. :D
thanks for all your videos

[beverlyshevenell]

I love your videos and use them in my AP chem classes. Just a comment on this one - when you talk about melting sugar you contrasted the "covalent bonds" in sugar with the ionic bonds in salt. I think you meant to talk about the hydrogen bonds between sugar molecules rather than the covalent bonds within the molecules.

Thank you SO MUCH for helping me with my chemistry!

Man, I love the music at the beginning and your videos are so great c: you're awesome!

Just Loved it❤... Explanation at its best level🥰

[JimNotCarrey]

Anyone know where I can find a video about unit cells, tetrahedral holes, coordination numbers, etc? This video helped but I want to get more in depth

[ellahappel]

ionic solids?? more like iconic solids dabdabdabdabdab

[dylanparker]

love your videos - thanks so much for making them

[oAbraksas]

Isn't this kind of bond the same as Van der Waals? What's the difference?

[FasAntick]

I get how the two atoms are bonded together but what I can't understand is how the whole structure is held together the ''inter-molecular forces'' I have been stuck on a question about the melting point of two substances, Carbon disulfide and aluminium sulfide, I can understand why the CS2 is a liquid at room temperature but not why the Al2S3 is a solid at room temperature.

Any help would be greatly apreciated.

There is nothing you keep there is only your reflection.

hi can u tell me Why ionic Bonds tend to form crystalline structure?

[raushansing_h]

It isn't poor conductor it is insulator in solid and conductor in MOLTEN state and in aqueous solution

Mate: 4:00, electrons don't travel through the solution, get a grip (otherwise nice vids).
