These are called isomers.
A scanning tunneling microscope. Used to take a picture of atoms and molecules in well-ordered arrays.
Strontium is a heavy metal, which is more usually found in ionic compounds than in molecules, however, it can form similar types of molecular arrangements to those of calcium.
An electron microscope.
They know because
Different molecules have different arrangements.
nothing
These are called isomers.
Geometric isomers are molecules that contain the same number and types of atoms, and bonds. They have different arrangements of the atoms.
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.
The answer depends on what the solid is: ice, a hydrate crystal, or something else.
A scanning tunneling microscope. Used to take a picture of atoms and molecules in well-ordered arrays.
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.
Because of the vibrating particles
cohesion
