How to write

Postby Rita Chen 1B » Tue Nov 26, 2019 8:22 am

How do I know how to write these hybridization? How does it relate to shape?

If you count the number of valence electrons, you can determine the atoms hybridization. For example if you have a Carbon atom, which has 2 electrons in the 2s and 2 electrons in the 2p orbitals, then these orbitals would combine to form a hybridization of sp3. This means that now the Carbon atom can form 4 bonds as we know from its Lewis structure, because if we listed it as its electron configuration, we are saying that the 2s electrons are a pair and cannot bond, leaving only the 2 2p electrons to bond. I don't know if that was clear, but I hope this helps.

How does it make a hybridization of sp3 though? how do you know how to write it (hybridization is big confusing).

To figure out the hybridization, you have to count the number of regions of electron density surrounding the atom. A single bond, double bond, triple bond, and lone pair each count as one region of electron density.

Number of regions
of electron density:
2 : sp
3 : sp^2
4 : sp^3
5 : sp^3d
6 : sp^3d^2

For example, the sp^3 hybridization would correspond to an atom with three regions of electron density, in which the s orbital and two of the p orbitals hybridize.
