Web29 Jan 2024 · A Lewis structure is a graphic representation of the electron distribution around atoms. The reason for learning to draw Lewis structures is to predict the number and type of bonds that may be formed around an atom. A Lewis structure also helps to make a prediction about the geometry of a molecule. Web17 Oct 2015 · As you can see, potassium has one valence electron located on the fourth energy level in the 4s-orbital. This means that its electron dot diagram will feature its chemical symbol and one dot, usually placed above the symbol. Bromine, Br, is located in group 17, period 4 of the periodic table. Its electron configuration looks like this
