its a physical change
it may look different but it is still in the same state as a solid piece of gold
i think that it is dull
A chemical property is the substance's response to other substances, resulting in a new substance. A physical property is something like a substance's lustre, melting point, boiling point, colour, or density, to name a few. Examples of chemical properties are: combustibility and reaction to acid.
A soft shining light reflected from the surface of something, for eg. the lustre of gold.
This is called the luster of the mineral.The luster of a mineral is the way its surface reflects light. Most terms used to describe luster are self-explanatory: metallic, earthy, waxy, greasy, vitreous (glassy), adamantine (or brilliant, as in a faceted diamond).
Lustre is a qualitative property of substances, which refers to it's 'shinyness' and generally refers to solid metals. Oxygen, however, is almost always found in gaseous form, and if it were to be solid, it would not be lustrous.
The lustre is a physical property of materials.

Luster is a physical property, not a chemical change. Luster refers to the way light interacts with the surface of a material, causing it to either appear shiny or dull. It does not involve any alteration of the chemical composition of the material.
It sort of has this dark metallic look to it
Copper is said to have an orangey-red metallic lustre.
A. Physical property because the metal is just getting shinier, not creating a new substance B. Physical property because the substance is changing form, not creating a new substance C. Chemical property because the substance is changing form during specific chemical reactions characterising an explosion and an ignition
Hydrogen itself does not have lustre as it is a colorless, odorless, and tasteless gas at room temperature. However, in its solid form as metallic hydrogen, it may have a metallic lustre.
Lustre.
Lustre is a physical property, because... Look up a few definitions of "chemical property." In every one you will find that it involves chemical reactions, or changes in the identity of a substance. Lustre (shininess) is a property that can be observed without any chemical changes to the substance, so it can't be a chemical property.
The lustre of a metal is how shiny the metal is.There are two different types of lustre. One is metallic lustre, which is like the shininess of a polished metal surface. The other is non-metallic lustre, which is the opposite of metallic lustre, but is still shiny
