"Using a tabletop laser, University of Rochester optical scientists have turned pure aluminum, gold. And blue. And gray. And many other colors. And it works for every metal tested, including platinum, titanium, tungsten, silver, and gold. Chunlei Guo, the researcher who a year ago used intense laser light to alter the properties of a variety of metals to render them pitch black, has pushed the same process further in a paper in today's Applied Physics Letters. He now believes it's possible to alter the properties of any metal to turn it any color-even multi-colored iridescence like a butterfly's wings. ..."

What else can I help you with?
The ability to oppose a change in shape?
The ability to oppose a change in shape is known as elasticity. Objects that exhibit elasticity can return to their original shape after being deformed. This property is commonly observed in materials like rubber bands, springs, and certain metals.
Can you shape metals by hitting them with a hammer?
Yes.
Why dont metals break when pounded into sheets or drawn into wires?
Metals have strong metallic bonding that allows their atoms to slide past each other when subjected to force, rather than breaking apart. This ability to easily change shape while maintaining cohesion is what allows metals to be pounded into sheets or drawn into wires without breaking.
Why don't metals break when pounded into sheets or drawn into wires?
because they are maleable and change shape without breaking due to yield point where material becomes plastic. The metal is strain hardened and becomes stronger
What should not be used to indicate a chemical reaction?
Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
Why do metallic substances change shape when struck?
Malleability is a property of all metals.
Is three properties of metals that are caused by metallic bonding?
they are shiny, ductile and malleable, which means that they can change shape.

Can you shape metals by hitting them with a hammer?
Yes.
What metals that start with ma can be hammered into a different shape?
Metals that start with "ma" that can be hammered into a different shape include malleable metals like copper and magnesium. These metals have properties that allow them to be easily hammered or shaped without breaking.
What is the difference between an alloy and a smart alloy?
An alloy is a mixture of two or more different metals or non metals whiles A smart alloy is an alloy that returns to it original shape when heated................................... An alloy is a mixture of a metal with at least one other element. A smart alloy is an alloy that will make one change when effected by an outside force (e.g.: heat, pressure, etc.) and will change back, whether that is a change in shape or produced voltage.
Is a change of a shape a chemical change?
no a change in shape is physical change
Why do metals change shape so easily?
Metals change shape easily because they have a high degree of ductility and malleability. Ductility allows metals to be drawn into wires, while malleability allows them to be hammered or rolled into different shapes without breaking. The metallic bonds between atoms are able to slide past each other easily, allowing metals to deform plastically.
Can its shape be change?
can solid change shape
What bond flattened and shape metals?
metallic bonds
Process causing protein shape to change in response to heat?
The process that causes protein shape to change in response to heat is called denaturation. When proteins are exposed to high temperatures, the interactions that maintain their specific shape are disrupted, causing the protein to unfold and lose its structure. This can result in loss of function and potential degradation of the protein.
Can the shape of metals be easily changed?
Yes, metals can be easily reshaped through processes such as forging, rolling, or extruding due to their malleability and ductility. These properties allow metals to be formed into various shapes without breaking.
