UNIT 2.1 TYPES OF CHEMICAL BONDS
Chemistry is the study of matter and interactions. Chemistry overlaps with many other sciences.
Below is the contents for this sub unit. If you have taken Chemistry 1, this should all be review but it is always good to brush up on the basics (significant figures especially).
TYPES OF CHEMICAL BONDS
No seriously, if you haven't reviewed some of my Chem 1 stuff, you should probably do this now.

Molecular Geometry and Polarity

Diving Deeper
​
Ionic bonds:
I gave you a short cut of metal to non-metal but it is actually the electronegativity difference between atoms that will determine if the electron gets transferred.
​
Covalent:
There is a range of how well the electrons are shared. In reality, the more electronegative the atom, the more likely the electron will be found near it (so not shared evenly). But if electronegativity is similar (like H and C) the electrons are shared evenly.
​
Polar:
I taught last year to think of the molecule and find out what is polar. Now we will do that with bonds.
Example:
CO is a triple bond. That is 6 electrons being 'shared'. Which atom do the electrons spend more time around? (look at electronegativity) Thus that atom will be slightly negative. The strength of that charge is based on the electronegativity difference.
​
Don't forget in metals only (alloys as well) valence electrons are considered delocalized (they aren't associated with a specific atom).
