In square close-packed layer, a molecule is in contact with four of its neighbours. Therefore, the two-dimensional coordination number of a molecule in square close-packed layer is 4.
A solid has tightly packed particles.
Density
If they're all standing up and tightly packed, perhaps 5,120 . If they're all resting flat on the floor, in a single layer and tightly packed, perhaps 2,230 .
they have a definite shape, the molecules are packed tight and it has volume and mass

Tightly packed, vibrating in place, has a definite shape and volume.

The solid molecules are tightly packed and have the strongest intermolecular forces.The gases are not at all tightly packed and have the weakest intermolecular force.
Red blood cells are packed full of a protein called hemoglobin. Hemoglobin has a molecule of iron in each protein molecule. This hemoglobin is what carries oxygen. The oxygen binds with the iron.

The only thing that they have in common is that they are proteins. Insulin is a molecule that carries glucose across the body cell membranes. Hemoglobin is a very large molecule that contains iron and carries oxygen. The red blood cells are packed with it.
It is easy to pour a liquid rather than solids because the molecule makeup of fluid is less packed than the molecule makeup of solids. In other words, the molecules of solids are more tightly packed than of fluids.
Metal is a perfect conductor of heat because the molecules are densely packed together so they can pass the heat quickly from one molecule to the other.

Molecule movement is the smallest in a solid. In a solid, the molecules are closely packed and have limited freedom to move and vibrate. In liquids and gases, the molecules have more space and freedom to move, resulting in greater molecular movement.
