Answer:
The ion's sizes and their radius ratio.
Explanation:
Ionic compounds take the form of three dimentional arrays by alternating anions and cations in order to minimize the potential energy of the system by maximizing the attractive force between opposite charges.
<em>The resultant geometric structures are known as crystal lattices and their arrangements depend on the ion's sizes and, since they are bound though electrostatic attraction, their radius ratio.</em>

The forces of Earth's plate movement can change a flat plain into landforms such as anticlines and synclines.
Answer:
depending on how you change the angle on the ramp the kanetic energy can go up or down depending on how u angle the ramp
Explanation:
Answer:
H2O> NH3>CH4
Explanation:
Now let us look at the issue of the approximate bond angles of each specie;
H2O- 104°
NH3 - 107°
CH4 - 109°
We can see that both species are based on a tetrahedron on the basis of electron pair geometry. How ever, we must also remember that lone pairs cause more repulsion around the central metal atom atom and distort the bond angles. Thus, in the presence of lone pairs, molecules depart from the expected shape predicted by valence shell electron pair repulsion theory. Hence, the repulsion of lone pairs in water (2 lone pairs) is greater than the repulsion in ammonia (1 lone pair) and repulsion in ammonia is greater than the repulsion in methane (no lone pair).
