WebJan 31, 2011 · There are balls drilled for the ideal angles for tetrahedral, trigonal bipyramidal and octahedral geometries. Your kit may have red balls, representing oxygen, drilled with only two holes instead of four because the positions of the lone pairs have already been taken into account. See Table 2 for the correspondence between ball color and element. WebIn the hexagonal family, the crystal is conventionally described by a right rhombic prism unit cell with two equal axes ( a by a ), an included angle of 120° ( γ) and a height ( c, which …
