Quartz and Glass having same molecular structure (i.e. SiO4) but Quartz is crystalline while glass is amorphous! why it is so??

$\mathfrak{\huge{\bf{✯\pink{A}\blue{N}\orange{S}\purple{W}\red{E}\pink{R}✯}}}$

❥Quartz is a mineral with the chemical formula SiO2, and like almost all minerals, it is a crystalline solid.

❥Quartz glass is an amorphous solid because it is formed by fusing the crystal and then cooling it rapidly.

❥Crystalline solids have regular ordered arrays of components held together by uniform inter-molecular forces, whereas the components of amorphous solids are not arranged in regular arrays.

❥Crystalline solids have a certain pattern of atoms that is repeated over and over in three dimensions.

Answer 2

Answer:

$\mapsto$ Quartz is a mineral with the chemical formula SiO2, and like almost all minerals, it is a crystalline solid.

$\mapsto$ Quartz glass is an amorphous solid because it is formed by fusion the crystal and then cooling it rapidly. Crystalline solids have regular ordered arrays of components held together by uniform inter-molecular forces, whereas the components of amorphous solids are not arranged in regular arrays. Crystalline solids have a certain pattern of atoms that is repeated over and over in three dimensions.
