10 Affordable Winter Getaways. For much of the United States, winter is a dark season of naked trees, stinging cold and a bulging waistline. (You have to keep warm somehow, and an alternating schedule of hibernation and gorging seems to accomplish this satisfactorily). But here's another option.
The totality of all such points is space lattice. Space lattice:it is the regular arrangement of the constituent particles(atoms,ions or molecules) of a crystalline solid in three dimensional space. Lattice points or Lattice sites:They are the positions occupied by the atoms,ions or molecules in crystal lattice.he totality of all such points is space lattice.

Molecule. the smallest particle of a substance that can exhibit all the chemical properties of the substance. A molecule is composed of atoms (more precisely, of atomic nuclei, their surrounding inner electrons, and their outer valence electrons, which form a chemical bond). The inner electrons of atoms usually do not participate in the formation of such bonds. The molecular composition and structure of a given substance do not depend on the method of preparation used. In the case of monatomic molecules (for example, inert gases), the concepts of the molecule and the atom are congruent.
