An electron microscope.
They know because
The scientist can use a transmission electron microscope (TEM) or a scanning tunneling microscope (STM) to take pictures of well-ordered arrangements of atoms and molecules. These instruments provide high-resolution images that can reveal the atomic structure of the material being studied.
These are called isomers.
Yes, substances can have fixed arrangements of atoms, particularly in solids where atoms are organized in a structured lattice or repeating pattern. In crystalline solids, this arrangement is highly ordered and consistent throughout the material. In contrast, liquids and gases have more disordered arrangements, with atoms or molecules moving freely and not maintaining a fixed structure.
True
They know because
Different molecules have different arrangements.

allotrope
The answer depends on what the solid is: ice, a hydrate crystal, or something else.
Isomers are molecules that have the same chemical formula but different physical arrangements of atoms. Glucose and galactose are two of the several sugars having the formula C6H12O6, but have different arrangements of the atoms in their molecules.
No, H2O (water) is not considered an isomer. Isomers are molecules with the same molecular formula but different structural arrangements. Water does not have other structural arrangements that would make it an isomer of itself.
Because of the vibrating particles
Stereoisomerism is a type of isomerism were the atoms that are in the molecules are the same and there arrangement are the same but there spatial arrangements are different to eachother.
Isomers are pairs of molecules that share the same chemical formula but have different structural arrangements. For example, glucose and fructose both have the chemical formula C6H12O6, but they have different structural arrangements.
