Step 1I'll solve this step-by-step using the guidelines you specified:
Step 2: Determine the electron configuration of gallium
- The electron configuration is $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 4s^{2} 3d^{10} 4p^{1}
- Gallium's atomic number is 31, so it has 31 electrons
Final Answer
Gallium (Ga) has 3 valence electrons.
