Which of the following is not a crystalline solid?
Which of the following is not a crystalline solid?
- MgCl
- BaCl2
- Glass
- Orthorhombic.
Hint:
Crystalline solids do not shatter unevenly when they are broken.
The correct answer is: Glass
- A crystalline solid is known as a homogeneous solid in which the molecules, ions, or atoms are arranged in a definite repeating pattern.
- Crystalline solids consist of regular arrays of components that are arranged in an orderly manner. They are joined by intermolecular forces. Glass, on the other hand, is amorphous in nature and not crystalline. Amorphous means a substance that lacks a clearly defined shape or form.
- It has technological, practical, and decorative use. It is used in doors and windows. And if we touch long standing glass, we can see that it's thicker near the bottom portion.
Glass is often formed by the process of rapid cooling of molten form.

Brownian motion is seen in _______
The atomicity of a molecule is the total number of atoms present in it.
Sulphuric acid (H2SO4) has one sulphur atom, two hydrogen atoms, and four oxygen atoms in it. Hence, a total of 7 atoms are present. Therefore, the atomicity of H2SO4 is seven.
