Why are atoms invisible to visible light?
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.
How is it possible for an electron go from the 3rd to the 4th energy level?
It is possible if the electron absorbs energy, for example, from a photon.
Can the radius of an atom can be measured directly?
No, the radius of an atom cannot be measured directly because atoms are incredibly small and their size is on the scale of angstroms (10^-10 meters), which is smaller than the wavelength of visible light. Instead, the radius of an atom is estimated using techniques like X-ray crystallography or scanning tunneling microscopy.
When the atom had been seen?
Strictly speaking, no one has ever seen an atom. It's not possible, since atoms are much, much smaller than the wavelength of visible light. The first imaging of individual atoms was done in the late 1970s. By the early 1980s, scanning tunneling microscopes were commercially available (and relatively inexpensive, as high-precision lab equipment goes).
What is happening in an atom when light is given off?
light is given off by an atom when and electron moves from one shell to a lower shell and a specific amount of energy is released in the process (known as a photon). If the wavelength of the released photon are in the spectrum of visible light, we will see it as a specific color based on the wavelength of the photon.

What causes an atom to release energy in the form of visible wavelengths of light?
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.
What part of an atom is visible under the microscope?
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.
How do you generate light?
Light can be generated in many ways, such as through incandescence (like in light bulbs), fluorescence (like in neon lights), phosphorescence, or by using electrical currents in LEDs. Each method involves the conversion of energy into electromagnetic radiation in the visible spectrum, producing light.

What color is the middle of a zinc atom?
The middle of any atom has no color because it is so very small that it can not be seen using light.
Why is nitrogen oxide colourless and nitrogen di oxide is brown gas?
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.
What is the active ingredient in a light sensitive emulsion that records the latent image and is later converted to a permanent visible image during developing?
A silver halide--a compound consisting of a silver atom bonded to either an iodine atom or a chlorine atom.
Who was the first person to see an atom?
No one has ever seen an atom. Which is not too surprising, when you consider that the shortest wavelength of light that our eyes can detect is more than 1,400 times the covalent radius (the "size") of the largest atom. To see an atom in visible light would be like trying to feel the outline of a mosquito by brushing it with a feeler the size of a person.
Why atom cannot be seen with naked eye?
Atoms are much smaller than the wavelength of visible light, making them impossible to see with the naked eye. The scattering of light by atoms is also not strong enough to make them visible. Additionally, the human eye is not sensitive enough to detect individual atoms.
