A scientist would use a scanning tunneling microscope (STM) or an atomic force microscope (AFM) to take pictures of atoms and molecules in well-ordered arrays. These instruments can generate high-resolution images by scanning a sharp probe tip across the sample surface to detect variations in atomic forces or tunneling current.
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.
When viewed through a microscope, atoms and molecules do not appear as solid spheres. Atoms are composed of a nucleus surrounded by a cloud of electrons, while molecules are made up of atoms bonded together in specific arrangements. These structures are too small to be directly observed using a traditional light microscope due to their size and the limitations of optical resolution.
A scanning tunneling microscope (STM) or an atomic force microscope (AFM) is typically used to capture images of atoms and molecules within a substance. These instruments use a sharp tip to scan the surface of a sample at the atomic level, allowing for visualization of individual atoms and molecules.

Scientists use techniques such as X-ray crystallography to determine the atomic structure of materials. By studying the diffraction pattern of X-rays passing through a crystal, scientists can infer the spatial arrangement of atoms and molecules in the material. This provides evidence that atoms and molecules combine in well-ordered arrays.

By looking at atoms and molecules with this tool, scientists have discovered that often atoms a nd molecules are arranged in orderly patterns
A scanning probe microscope can provide a three-dimensional image of atoms or molecules on the surface of an object.

Things To See Closer And Deeper Into The Thing They Are Looking At.
Cells yes, molecules for the most part no, atoms definitely not. A few extremely large molecules can be seen with light or electron microscopes (or even with the naked eye... technically, a flawless diamond is one large molecule), but normally something called a scanning tunneling microscope is used to image molecules and atoms.
some microscopic things could be molecules, atoms,and anything that you can see under a microscope
