"Mengxi Brush Talk" shows a lot of scientific knowledge with its rich records. Today, it imitates its style, with "Aluminum Fluoride Alf3 Lewis Dot Structure" as the core, and an essay.

To taste the science of chemistry, there is something called Aluminum Fluoride, which is called AlF
. Its Lewis Dot Structure shows the distribution of electrons between atoms.

If the husband of Al, aluminum also has three outer electrons. Fluoride, F also, has seven electrons in each outer layer. When the two combine to form AlF
, aluminum is divided into three fluorine atoms with its three electrons. Therefore, the electron shell of aluminum is full of eight corners, and fluorine each gets one electron, which is also in a stable state.

Look at the Lewis Dot Structure. Aluminum occupies the center and connects the trifluorine atoms with lines to express its chemical bonds. The fluorine atoms are surrounded by eight electrons each, showing a stable appearance. This structure shows that scholars have understood the principle of atomic bonding in AlF and has helped a lot in the study of chemistry. Although ancient books did not contain this structure, today's science can be studied in detail. It is also seen that the progress of knowledge is new and new.
