Scientists use electrons instead of light to see atoms because electrons have a smaller wavelength compared to visible light, enabling them to resolve smaller details of atomic structures. This allows scientists to achieve higher resolution images and better analysis of atomic structures using techniques such as electron microscopy.

When ultaviolet light is incident upon glass electrons within atoms in the glass?
When ultraviolet light is incident upon glass, the electrons within atoms in the glass absorb the energy from the light. This absorbed energy can cause the electrons to move to a higher energy state, leading to the emission of light in the form of fluorescence or phosphorescence.
How does electrical current produce light?
Electrical current passing through a material can excite its electrons, causing them to jump to higher energy levels. When these excited electrons return to their original energy level, they release the extra energy in the form of light, producing visible light in the process. This is the principle behind how electrical current produces light in devices like light bulbs and LEDs.
What microscope use a beam of electrons instead of light?
An electron microscope uses a beam of electrons instead of light to magnify specimens. This allows for higher resolution images and the ability to view smaller details compared to light microscopes.
How does electricity produced lighting?
Different kinds of light use different mechanisms. Currently, the technologies used include incandescent lights, fluorescent lights, and LEDs.In an incandescent light (that's the most wasteful light), a current heats up a wire, until it glows.In a fluorescent light, the current excites atoms, i.e., it raises electrons to a higher energy level. When the electrons fall back, they emit light.I believe LEDs work on a similar principle, i.e., exciting the atoms; however, the material is solid instead of a gas.Different kinds of light use different mechanisms.

What are delocalized valence electrons?
Delocalized valence electrons are electrons in a molecule or solid that are not associated with a specific atom but instead spread out over multiple atoms. They are free to move throughout the material, giving rise to properties like electrical conductivity in metals and the ability to absorb or emit light in certain organic compounds.
Why do scientist use electrons for microscopes instead of light?
Scientists use electrons for microscopes instead of light because electrons have a shorter wavelength compared to visible light, allowing for higher resolution and better magnification. Electron microscopes can visualize smaller structures and details than light microscopes, making them essential for studying very small objects like individual cells or molecules.
What can scientists measure to provide evidence that electrons can move from one energy level to another?
Scientists can measure the amount of energy absorbed or emitted by electrons as they transition between energy levels. This can be done through spectroscopy techniques like absorption or emission spectroscopy, which can reveal the specific wavelengths of light absorbed or emitted during these transitions. By analyzing these spectral lines, scientists can provide evidence that electrons can indeed move between energy levels.
What scientist discovered that the light released by atoms of gases is related to the energy of electrons?
Niels Bohr discovered that the light released by atoms of gases is related to the energy of electrons. He proposed the atomic model that states electrons orbit around the nucleus in discrete energy levels, which explains the different light emissions observed from atoms.

When ultraviolet light is incident upon glass, the electrons within atoms in the glass absorb the energy from the light. This absorbed energy can cause the electrons to move to a higher energy state, leading to the emission of light in the form of fluorescence or phosphorescence.
In the photoelectric effect what happened when light hits the metal?
electrons are knocked off atoms causing electricity to flow

Absorption of light by atoms of an element occurs when photons are?
Absorption of light by atoms of an element occurs when photons of light with energy levels matching the energy levels of the electrons in the atom are absorbed. This causes the electrons to move to higher energy levels, and the atom becomes excited, leading to the absorption of light.
