Electron domain molecular geometry table12/11/2023 ![]() ![]() What do you think it is when there are four atoms connected to the center? When there are three atoms around the central unit, the optimal angle is 120 o: In this case, putting them across at 180 o allows for achieving the optimal geometry: An orientation that puts them as far away as possible with the same angle between all. Keeping in mind that the blue atoms repel each other, propose an optimal geometry for them. The red sphere represents the central atom and the blue ones are connected to it: Let’s use this model examples to illustrate how this works. It is the keyword and all you need to grasp this concept is keeping in mind the idea that atoms want to stay as far apart from each other as possible because of the repulsion between the electrons on them. ![]() First, what does VSEPR stand for? It is the Valence Shell Electron Pair Repulsion theory. You may choose to begin with six balloons in an octahedral geometry and show other molecular shapes by popping one balloon at a time.In today’s post, we will discuss the VSEPR theory which helps us understand the geometry of molecules. Alternatively, labels and string can be used to hang air-filled balloons from classroom walls. The helium in each balloon will lift it toward the ceiling and keep the models out of the way during other classroom activities. During model assembly, tie the free end of the string to the connection point between balloons. (To aid in retrieval, the string should be 6 feet less than the height of your classroom celling). ![]() Before creating each model, create a note card label and attach it to a long piece of string.
