This way 24 out of the 28 fluorine atoms have already taken their space, leaving aside two sets of electrons. However, when it comes in contact with water, it reacts with it and releases xenon gas, molecular oxygen, and xenon fluoride. So, to have a stable structure, the non-bonding electrons are placed in a plane that is perpendicular inside an octahedral setting. These structures help develop a better understanding of chemical bond formation in a molecule and also the number of non-bonding electrons. G. N. Lewis is well known for multiple contributions to the study of chemistry. 4: Sigma and pi bonds. For the compound {eq}XeF_4 What is the electron pair geometry of this molecule?
