I'll solve this problem step by step, following the LaTeX formatting guidelines precisely:

Step 2
: Determine the Lewis Structure

- Total valence electrons: $$3 + (3 \times 1) = 6$$ electrons
- Borane (BH₃) is a molecule composed of one boron (B) atom and three hydrogen (H) atoms - Boron has 3 valence electrons - Each hydrogen contributes 1 electron

Final Answer

- Molecular Geometry: Trigonal Planar - Bond Angles: 120^{\circ}
