—Why complexes with six-fold coordination have an octahedral shape, such as those formed by metal ions with H2O, OH- and NH3

Understand why complexes with six-fold coordination have an octahedral shape, such as those formed by metal ions with H2O, OH- and NH3 as ligands.

Use —why complexes with six-fold coordination have an octahedral shape, such as those formed by metal ions with h2o, oh- and nh3 to connect the rule to the data and decision in the question.

This matters because —why complexes with six-fold coordination have an octahedral shape, such as those formed by metal ions with h2o, oh- and nh3 determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —why complexes with six-fold coordination have an octahedral shape, such as those formed by metal ions with h2o, oh- and nh3 to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Why complexes with six-fold coordination have an octahedral shape, such as those formed by metal ions with H2O, OH- and NH3 is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
