2.22 angstroms is the distance between Si atoms in solid silicon.

No. Silicon exist as a covalent network solid in which each atom is bonded to 4 adjacent atoms.
Ice is a solid made up of moleculs, H2O. Generally when a solid melts the distance between the molecules (or atoms if it is sya a metal) increases.Water is very unusual in that the solid form is lessdense than the liquid, which is why icebergs float. The reason is that solid water forms a hydrogen bonded lattice that is quite "open" and the mean distance between molecules is actually greater in the solid than in the liquid hence the lower density.
The force between atoms of a solid is inter-particle force.
At room temperature the element silicon is a crystalline solid.If it was not a crystalline solid, the computer you have in front of you would not be possible (or would be much bigger and consume much more power).Do not confuse the element silicon with various compounds called silicone, which are oils and polymers that have silicon atoms in their molecules instead of carbon atoms, and can be either liquids or solids. There are also silicon compounds that are gases (e.g. silane, chlorosilane, fluorosilane, chlorofluorosilane).

The distance between molecules in a solid is not very far at all. In fact in some solids there is no distance.

Silicon Dioxide is a solid.
Silicon is a solid at room temperature.
Atomicity, what a charming old word. Used to mean either valency or the number of atoms in a molecule. For silicon the valency is 4. (where valency was the numebr of bonds that could be formed) Silicon is not molecular, it is normally encountered as a solid with a network lattice.
