Formal charge is defined as the charge assigned to an atom of a molecule.
In , sulfur is the central atom. Therefore, formula to calculate the formal charge will be as follows.
Formal charge = Valence electrons -
Valence electrons in sulfur are 6 and lone pairs on sulfur are zero. Number of bonded electrons of sulfur are 8.
Therefore, formal charge on sulfur atom will be calculated as follows.
Formal charge = Valence electrons -
= 6 -
= 6 - 4
= 2
Thus, we can conclude that the formal charge on sulfur in is +2.

A regular three-dimensional arrangement of constituent particles in a crystal in which each particle is represented by a point is called crystal lattice.

Crystal Lattices
- Crystalline solids have a regular and periodically repeating pattern of constituent particles.
- The diagrammatical representation of three dimensional arrangements of constituent particles of a crystal in space with each particle depicted as a point is called crystal lattice.
- There are only 14 possible three dimensional lattices and are known Bravais Lattices.
- Each point in a lattice is called lattice point or lattice site.
- Each point in a crystal lattice signifies one constituent particle which can be an atom, a molecule or an ion.
- Lattice points are joined together using straight lines to identify the geometry of the lattice.

Gay-Lussac\'s Law of Combining Volumes:
When gases react, they do so in volumes which bear a simple ratio to one another, and to the volume of the gaseous product, provided that all the volumes are measured at the same temperature and pressure.
Example:
One volume of hydrogen when mixed with one volume of chlorine, gives two volumes of hydrogen chloride gas at the same temperature and pressure.
H2 + Cl2 → 2HCl
Thus the ratio 1:1:2 is simple.
