What is the luster of hydrogen?
The element hydrogen does have a metallic form, which exists under conditions of both low temperature and high pressure. Under more usual conditions hydrogen is a gas and as such, has no luster. As a metal it has a metallic luster much like other metals.
Why Is Streak A Useful Property For Identifying Minerals?
The streak of a mineral is much more accurate in identifying a mineral than color. The streak of a mineral can distinguish minerals with metallic and non-metallic luster. For example, metallic minerals generally have a dark streak whereas non-metallic luster minerals often have a light colored streak.
Is aluminum more metallic than boron?
Yes, it is more metallic. Al has an extra full shell of electrons which shields the positive charge of the nucleus. This means that the outer electrons are held less tightly by the nucleus and therefore lost more easily making it a more metallic element
Why is copper more metallic than it should be in theory?
Either something is a metal, and is therefore metallic, or it is not. The terms are fixed.
What is the colour of bromine?
The element bromine is a red-brown liquid at room temperature. When it is cooled to below -7.2 °C, or 19 °F, it changes phase to a solid. If seen in that solid state, it has a metallic luster to it. Wikipedia has more information, and a link is provided below.It is a Dark Red liquid
Why graphite a nonmetal?
Graphite is a form of the element carbon, which is a nonmetal. While it has a metallic luster and conducts electricity, graphite is brittle. Unlike metals, which are held together by metallic bonds, graphite is a covalent network solid. Other forms of carbon behave more clearly as nonmetals.
Is metallic luster more common than non-metallic luster?
no
Is slate grey the same as graphite grey color?
Slate varies in color, but gray is one of the more common colors. Graphite can easily be distinguished from slate by its color. Slate has a dull luster while graphite appears metallic.
What is the luster of hydrogen?

Is shale shiny or dull?
It can, but is usually more of a gray colour.

Do metallic compounds have the same properties as the original metals or new proerties?
Chemical compounds have very different properties compared to metals.Metallic compounds have more similar qualities to original metals. All of these metals are good conductors of heat. All of them have a luster.
Why is a diamond more valuable than graphite?
Both graphite and diamonds are both made up of carbon and their chemistry is one of the most important similarities that they have. Due to the fact that these minerals are highly solid and have a high melting point makes it very difficult to burn. Even though both of these minerals are chemically the same in composition, they are different in physical form and in other aspects. Even a non- expert can tell the difference between graphite and diamonds; graphite is more metallic and opaque and diamonds are transparent and brilliant.
What is a mineral that reflects light like a peice of foil has a metallic what?
some minerals have a metallic lustre, like galena (PbS) ans look like pieces of metal. Most minerals (maybe all?) with metallic lustre are opaque (do not alow light through). Metally looking is generally a good way to decide if it is metallic or not, but other similar discripticve terms are:Adamantine lustre: More shiny/reflective than glass (which has a vitreous lustre), but usually only occurs on minerals which are translucent or transpherent and which have a high refractive index, such as zircon.Greasy lustre: similar to metallic, often on opaque minerals. semi metallic but with variatons in texture and not quite as shiny as a metallic lustre. Graphite tends to have a semi metallic to greasy lustre.make sure that when you check for lustre on a sample, you look at a fresh face of the crystle, not one which is worn, weathered, altered in some way or too granular.
Where is graphite found in Canada?
Graphite in CanadaThere are 2 types of graphite - natural and synthetic. Natural graphite is black with a sub-metallic lustre, feels greasy and stains the fingers. Graphite is found mainly in METAMORPHIC ROCKS, most frequently in schist and as small crystals in impure marbles in association with other minerals. Timcal Canada Inc, in Lac-des-�les, Quebec, is the only graphite producer in Canada. Other producing countries are Ukraine, Brazil, India, North Korea, Republic of Korea and Mexico.See attached website for more information.
Graphite is more common than diamond?
Yes, graphite is more common than diamond.
What is more metallic mg or s?
Mg is more metallic.
