The four major categories for crystals are based on the structural elements and forces they exhibit: atomic and molecular crystals, ionic and ionic crystals, as well as metal and molecular crystals.

Common atomic cristals: Simple substances and some compounds belonging to the fourth A element in the periodic table are called atomic crystals. These include silicon crystals (SiO2, SiC), diamonds, SiO2 and other simple compounds.

Ionic crystal: This crystal forms by bonding the ions of different ions. (Quite a lot)

Metallic crystals are elements that can be used to make metal alloys.

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 and all organic substances.

The chemical formula of any salt (or salt) is the simplest structure XmYn. You can dissolve certain amounts of the salt in water.

Hydroxylation of substances created by elements from the short cycles can be achieved by using NaH and MgH2, or MgS.

A common feature of water reactions is the combination of positive elements and OH. Negative elements are combined with H to produce the appropriate substances.

The ones that match the question’s meaning are
