If we examine the central Br atom in the BrF Lewis structure, we find that it has 5 unbonded electrons. In other words, it has two lone pairs of electrons in Br and one unpaired electron.
There are six free electrons. Each fluorine atom contains three lone pairs of electrons, or three fluorine atoms in total. Brf Lewis octet rule structure. Lewis structures, often referred to as Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDS), are diagrams that depict the interactions of atoms in molecules as well as any lone pairs of electrons that may be present. The elementary electric charge of the electron, a subatomic particle, is a negative one.
