Hydrogen and Bromine Valence Electrons

Dr. B explains how to draw the Lewis structure for hydrobromic acid (HBr). He starts by identifying the valence electrons of hydrogen and bromine, which are 1 and 7 respectively, totaling 8. He then demonstrates how to draw the structure by bonding hydrogen and bromine, ensuring hydrogen has a full outer shell with 2 electrons and bromine with 8. The video concludes with a verification of the structure and a thank you from Dr. B.
