In very rough numbers, good enough to get a feel for the comparison . . .
Wavelength of visible light . . . . . call it 400 - 750 nanometers
Atomic diameter . . . . . 62 - 520 picometers (from a couple of on-line sources)
400 x 10-9 / 520 x 10-12 = 769
750 x 10-9 / 62 x 10-12 = 12,097
All wavelengths of visible light range from 770 to 12,000 times the diameter of all atoms. (rounded)
When an atom releases energy in the form of visible wavelengths of light, it indicates that an electron in that atom has gone from an excited energy level, back down to a lower energy level.
No, atoms are too small to be directly observed with visible light as their size is much smaller than the wavelength of visible light. To see atoms, scientists use techniques such as electron microscopes or other sophisticated imaging methods that can detect them indirectly.
Atoms are typically smaller in size than the wavelength of visible light, which makes them difficult to detect using visible light. Additionally, atoms do not absorb or reflect visible light in a way that allows them to be seen by the human eye. Special techniques such as electron microscopes are often used to visualize atoms.
A single atom is not visible in a microscope (it is too small to be imaged by photons). What you see in an optical microscope (or in general) is the light reflected, scattered, or emitted by the electron layers of the material under observation.
Not at all; the cesium atom is far bigger than the lithium atom.

No, a beam of light is not visible as it passes through a colloid because the particles in the colloid are small and do not scatter light significantly, unlike in a suspension where the particles are bigger. This lack of scattering prevents the beam of light from being visible.
The barium atom has a much bigger radius.
The wavelength of visible light is longer than a human skin cell. Visible light has wavelengths ranging from about 400 to 700 nanometers, while a human skin cell is typically around 30 micrometers in size.
neutral atom
Nitrogen oxide (NO) is colorless because it consists of only one nitrogen atom and one oxygen atom, which do not absorb visible light. On the other hand, nitrogen dioxide (NO2) is a brown gas because it consists of one nitrogen atom and two oxygen atoms, leading to the absorption of light in the visible spectrum, giving it a brown color.
A silver halide--a compound consisting of a silver atom bonded to either an iodine atom or a chlorine atom.
