Before class on Tuesday:
- Please watch the following 2 videos. (17 min, 18 min). Follow along with the notes I gave you in class. I will finish the last page of the notes in class
- Make a comment below.
- If you missed class on Friday for the field trip, I will included videos on geometry that cover what we discussed in class.

chemistry matters 
In this video I learned about how electrons share electrons in covalent bonds. I learned how electrons came together to form the geometries they do and about hybridization. Hybridization occurs when (step 1.) electrons from a lower orbital gain energy to move to a higher orbital (step 2.) come together to form a new kind of equivalent orbital. If there is only 1 s orbital and 1 p orbital overlapping, then it would form an sp orbital, if 1 s and 2 p shells overlapped it would form sp^2, if 1 s and 3 p orbitals overlapped then it would form sp^3, if 1 s, 3 p, and 1 d overlapped it would form sp^3d^1, etc. I learned how geometries could be predicted using this knowledge. I also learned about sigma bonds and pi bonds. Pi bonds are double bonds that are formed above and below sigma bonds and overlap side-to-side instead of head-to-head.

Hybridization refers to the changing of bonding around the central atom. In order to determine which hybrids an atom can make in order to allow it to bond with other elements, the number of orbitals are added. Then, the s orbital can move 1 electron down, and so on, until new valence shells are formed.

In this video, I learned hybridization of orbitals and gained a better understanding how the bonds of a specific can be equal despite the outer electrons coming from different orbitals. Another easy way to remember what type of hybridization of a bond is analyzing the electron pair geometry

In this lesson, I learn how to use hybrid orbital to determine the compound geometry.
Question: in the lest example with the H-C—C-H, why does the illustratiion of Carbon e- configuration bonds with two H when the picture printed in the packet show that C bonds with one C and one H on either side?

Today I learned about overlap bonding and hybrid orbitals.I also learned what Hybridization is and how it works.

Hybridize is something that is done so that equal bonds are formed between atoms in a molecule. The name of hybrid orbitals come from the name of orbitals and number of sub-level in those orbitals. Sigma bonds are in-between the inter-nuclear axis, while the pi bonds are above and below the inter-nuclear axis.

I learned about hybridization and how that determines the geometries as well as the types of bonds it has.
