What change of the surface when freshly cut lithium metal reacts with air?
Aaron schneider
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.
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
Why is the Hubble space telescope covered in reflecting metal foil?
To prevent it from overheating when the sun shines on it.
Is brittle a physical property of metal?
some metals (cast iron for example) are brittle- it is a physical property

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 mineral shines like metal?
Most metallic minerals have a metallic luster on freshly fractured surfaces. Silver and gold are examples of minerals with metallic luster.

When you describe a metal surface as smooth what property are you describing?

When a source of dim orange light shines on a photosensitive metal no photoelectrons are ejected from its surface What could be done to increase the likelihood of producing photoelectrons?
increase the brightness of of the orange light source
Is copper property of metal?
Not really. Copper IS a metal, not a property of metal.
Is luster a noun?
The word 'luster' is both a noun and a verb.The noun 'luster' is a word for the visual property of something that shines with reflected light; a surface coating for ceramics, porcelain, metal, etc.; a word for a thing.The verb 'luster' is to coat something with a glossy finish.
