What change of the surface when freshly cut lithium metal reacts with air?

What device gives off electrons when light shines on a metal surface?
There is the photoelectric effect, which is the process that emitts electrons from a metals surface when light of a certain frequency shines on the surface. In the metal, the nuclei are surrounded by electrons, so when the incoming electrons strike the surface, they pull apart from the electrons of the metal because of how like charges detract from each other.
Is beryllium lustrous?
Yes, beryllium is a lustrous metal. It has a shiny surface when freshly cut, but can develop a dull patina over time due to oxidation.
What chemical properties would you expect caesium to have?
Caesium is freshly cut, it have a metallic shine, but this disappears rapidly due to reaction of exposed metal surface with oxygen in the air
Is zinc luster?
If you're asking whether zinc has lustre or not, then yes, it does. That's because its a metal.
A typical property of a metal surfaces when freshly cut or polished?
Shiny.
Why freshly cut metal has lustrous surface?
Freshly cut metal has a lustrous surface because the cutting process breaks the continuous oxide layer on the surface, exposing the clean metal underneath. This clean metal surface reflects light well, giving it a shiny appearance. Over time, the exposed metal will form a new oxide layer, which may diminish its initial luster.
What change of the surface when freshly cut lithium metal reacts with air?

What device is known when electrons are emitted when light shines on a metal surface?
The device you are referring to is a photoelectric cell or a photodiode. When light shines on the metal surface of these devices, electrons are emitted in a process called the photoelectric effect, which generates an electric current.
What would you see if you were holding a metal that had luster?
If the metal had a metallic luster, on a freshly exposed, non-weathered surface, you would see a somewhat shiny, opaque surface.
What device makes electrons emit when light energy shines on a metal surface?
You think probable to an ultraviolet lamp.
Is neptunium shiny?
The fresh surface of neptunium is silvery.
Is shiny metal a physical property or chemical property?
Shiny metal is a physical property because it can be observed without changing the chemical composition of the metal. It is a characteristic related to how light interacts with the surface of the metal.

Explain why the surface of sodium is only shiny when it is freshly cut?
The shiny appearance of freshly cut sodium is due to its high reactivity with oxygen in the air. When sodium is exposed to air, it quickly reacts with oxygen to form sodium oxide, which creates a dull, opaque layer on the surface of the metal. This layer of sodium oxide obscures the shiny surface of the metal, giving it a dull appearance. Therefore, only freshly cut sodium displays its characteristic shiny appearance before it reacts with oxygen in the air.
Is beryllium lustrous?
Yes, beryllium is a lustrous metal. It has a shiny surface when freshly cut, but can develop a dull patina over time due to oxidation.
