Document Summary
436 [00:00:01. 41] hi, in this video, we will discuss some of the ways that atoms and molecules bond. These topics will be review to many of you, it"ll be new to some, but it"s. 438 important that we"re all get on the same page, so we can have more discussions. 439 [00:00:18. 72] we"ll talk about covalent and ionic bonds, and we"ll talk about hydrogen bonding, 440 which is a particular type of electrostatic interaction. 441 is one way that molecules will separate and organize. And we"ll sort of drive it home with two. 442 rules of thumb, which we"ll talk about over and over in this course. 443 opposite charges attract and like charges repel. 444 saying that oil and water don"t mix. 445 [00:00:55. 85] to start the discussion, we want to talk about how atoms can be held together, 446 either by covalent bonds, or ionic bonds. In the first case they share electrons, in the second case.
