Gallium atomic radius

Gallium has a beautiful silvery-blue appearance it wets glass, porcelain, and most other surfaces (except quartz, graphite, and Teflon) and forms a brilliant mirror when painted onto glass. Selected physical constants of gallium are summarized in Table 1. The atomic radius and first ionization potential of gallium are almost identical with those of almninum and the two elements frequently resemble each... 

The Periodic Trends Atomic Radii movie (eChapter 7.3) describes the trends in the sizes of atoms on the periodic table—from left to right and from top to bottom, (a) What factors influence atomic radius (b) Based on the factors that influence the atomic radius, explain why the radius of gallium is smaller than that of aluminum. 

Using only the periodic table, arrange the following elements in order of increasing atomic radius aluminum, boron, indium (Z = 49), gallium (Z = 31). 

Mirbt and coworkers [42] proposed that the underlying mechanism behind the formation of a mixed heterodimer is the huge difference in atomic radii of the atomic species involved (indium and gallium). They found, for cation-rich conditions, that the stress energy of reconstructions involving interconnected cation dimers (e.g., Ga-Ga or In-In) increases with increasing anion atomic radius. The reduction of the TE by the dimer formation A could therefore be smaller for symmetric dimers (e.g., Ga-Ga or In-In) than that for mixed dimers. The covalent radii of In and P differ by 0.034 nm, while for Ga and As, the difference amounts to 0.006 run (Table 13.1). This would also explain why such structures are not formed on GaAs(OOl). 

Gallium(III) ion takes the six-coordinate solvation structure in trimethyl phosphate (TMP) as in water from the measurement of EXAFS and the comparison between some metal ion solvation. The results also show the bond length between the solvated metal ion (Mn , Fe , Co , Ni , Cu , or Ga ) and oxygen atom of each solvent (EtOH, MeOH, DMSO, TMP) is much similar to that in water. However, the coordination number of the Zn ion even in the larger ionic radius than the Gd", decreases in DMA and TMP, i.e., the coordination of DMA or TMP with such metal ions may influence their charge density than ionic radius. 

Gallium (Ga) crystallizes in a simple cubic lattice. The density of gallium is 5.904 g/cm. Determine a value for the atomic or metallic radius of gallium.
