I’m not really sure just trying to get points but maybe it’s length
Answer:
the molecular geometry of BCl3 is trigonal planar.
Explanation:
<span>From the Born–Landé equation the lattice energy U ∝ (Z+ × Z-) / (r+ + r-) where Z+ and Z- are the charges on the cation and anion, respectively; r+ and r- are radii of the cation and anion, respectively.
The Z+×Z- term dominates. MgO has 2×2 (4) so it will have the higher U than Li2O Z+ × Z- = 2.
You only consider (r+ + r-) term when the Z+×Z- term is the same; smallest the (r+ + r-), the larger is the U.
U(MgO) = 3795 </span>kJ mol^-1
<span>U(Li2O) = 2799 kJ mol^-1
MgO has larger.

Compounds are composed of 2 or more different elements, ionically and or covalently bonded that results in substances containing elements in their respective definite amounts within the compound.
Hypothesis
Therefore the last step in the scientific method is proposing a hypothesis or obtaining a conclusion
