Discussion Overview
The discussion centers on the atomic radius of Gallium (Ga) compared to Aluminum (Al) and how the presence of d-orbitals in Ga may influence its size. Participants explore the implications of d-orbitals on atomic radius, referencing various sources for atomic measurements.
Discussion Character
Main Points Raised
- One participant states that the atomic radius of Ga is smaller than that of Al due to the presence of d-orbitals in Ga.
- Another participant counters this by providing atomic radius values, claiming Al has a radius of 125 pm and Ga has a radius of 135 pm.
- A third participant references a Wikipedia article that lists the atomic radius of Al as 143 pm, suggesting discrepancies in the data.
- A fourth participant shares links to a website that provides atomic radius values, indicating a disagreement with the previous claims.
- A fifth participant expresses confusion over which source is accurate regarding the atomic radii.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the atomic radii of Ga and Al, with multiple competing values presented and confusion expressed regarding the reliability of different sources.
Contextual Notes
Participants reference various sources for atomic radius values, which appear to differ. The discussion highlights the potential for varying definitions or measurements that may affect the conclusions drawn.
