Step 1: Determine the total number of valence electrons in the HBr molecule.
Hydrogen (H) is in the 1st period of the periodic table and has 1 valence electron. Bromine (Br) is in the 4th period and has 7 valence electrons, as it is in the same group as other halogens. Therefore, the HBr molecule has a total of 1 + 7 = 8 valence electrons.
Step 2: Draw the skeletal structure of HBr.
Since HBr is a diatomic molecule, its skeletal structure consists of two atoms, hydrogen (H) and bromine (Br), connected by a single bond.
Final Answer
The Lewis dot structure of HBr is shown above, with hydrogen and bromine connected by a single bond, and bromine having two lone pairs of electrons.
