SUMMARY
The atomic radius of Gallium (Ga) is 135 pm, while Aluminum (Al) has an atomic radius of 143 pm, contrary to some textbook claims that suggest Ga's radius is smaller due to the presence of d-orbitals. The confusion arises from varying sources, with some textbooks stating Ga's radius is smaller than Al's. The presence of d-orbitals in Ga contributes to its electron shielding effect, influencing atomic size and leading to discrepancies in reported atomic radii.
