Hybridization

Hybridization is the idea that atomic orbitals fuse to form newly hybridized orbitals, which in turn, influences molecular geometry and bonding properties. At first, it was a slightly challenging concept to grasp. But with practice, it became easy and I began to realize the patterns that never change.

Chemical Bonding Lab

In this Lab we were to apply our skills that we had learned from lecture in the previous days about Lewis structures and electron geometry. Electron geometry is just the type of format of the covalent bond based on the number of domains. I will provide material below to further expand your knowledge from this lab.

Lewis Structure

The Lewis structure is a representation of chemical bonds and elements based on its valence electrons. Many of theses diagrams are used to help diagnosis the electron geometry of the covalent bond. Any easy way to do these structure is count all the the electrons in the atom, place least electronegative element in the center, and place electrons throughout the bonds.

Periodic Trends

We learned periodic trends, and putting them to practice with a few activities. The first trend is atomic size, where atoms get larger because you move down a group, and also get bigger as you move from right to left, leaving the largest atoms in the bottom left corner. The next trend is ionization energy, which is the energy needed to remove an electron from a gaseous state atom, and it results in forming a cation. This trend is at its greatest in the top right. The third trend regarding only the s and p blocks, along with the two previous trends is electron affinity, which is the ease with which an electron may be added to an atom, creating an anion, otherwise, the energy given off when an electron joins an atom, and this gives off negative energy. This trend is also at its greatest in the top right. The final trend we learned about in our supplement is electronegativity, which is the tendency of an atom to draw electrons toward itself when chemically combined with another element, and this is greatest to the right and up, but does not include noble gases. 
This overall demonstrates all the trends:
