Valence Electrons in SiBr4

The video tutorial explains the Lewis structure for silicon tetrabromide (SiBr4). Silicon, with four valence electrons, is placed at the center, surrounded by bromine atoms, each with seven valence electrons. The total of 32 valence electrons is used to form bonds and fill the octets of all atoms, resulting in a stable Lewis structure for SiBr4.
