The four major categories for crystals are based on the structural elements and forces they exhibit: atomic and molecular crystals, ionic and atomic crystals, metal crystals, and molecular crystals.
Common atomic cristals: Simple substances and compounds belonging to the fourth A group elements of the periodic table, SiO2, SiC are all examples.
Ionic crystal is formed when ions are bonded together. (Quite a lot)
Metallic crystals – Metallic elements and metal alloys can be described as metallic crystals.
Molecular crystal: A crystal made by the interaction of molecules with van der Waals Force. Molecular crystals, in their solid state, consist of the majority nonmetallic basic substances and compounds. These include dry ice (CO2) or I2 as well most organic substances.
The chemical formula for salts is the simplest structure XmYn. You can dissolve certain amounts of salt in water.
Hydroxylation of substances formed from elements during the short cycles can be achieved by NaH and MgH2, SgS, SiCl4, SiCl4, PCl3, or PCl5, among others
A common feature of water reactions is the combination of positive elements with OH. The reaction that produces corresponding substances with negative elements involves the addition or subtraction of H.
These are the ones that correspond to the meanings of the question
(3) The NaH+=NaOH+H2 can be used
