Which metal ores are found naturally?
unreactive metals, such as gold
What is reactivity of properties of metals?
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.
Where does unreactive metals go in the periodica table?
Unreactive metals are typically found in the far right column of the periodic table, in group 18 known as the noble gases. These metals have a full outer electron shell, making them stable and unreactive. Examples include helium, neon, and argon.
What is the metallic properties?
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.
What type of elements are the metals rhodium platinum and palladium?
These metals are members of the family of platinum metals; they are very unreactive, scarce and expensive.
What two unreactive metals are found native?
Gold and platinum are two unreactive metals that are found in their native state, meaning they are found in nature in their pure form without the need for further processing.
How can you prove that gold is a metal and plastic is a non metal as both of them are unreactive?
Metals are conductive.
Why is gold often found as a metal in the ground?
Metals found native in the ground are metals which are so unreactive that they are still found unchanged or "native"
Why are metals like aluminum never found in the Earth as pure metals?
Aluminium is a reactive metal and in nature only the most unreactive metals (such as gold) are found in thir pure form.
Are gold and platinum reactive metals?
Gold and platinum are both considered noble metals because they are resistant to oxidation and corrosion, making them relatively unreactive compared to other metals. However, platinum can react with certain strong oxidizing agents under extreme conditions. Gold, on the other hand, is highly unreactive and does not tarnish or corrode easily.
Are alkali metals considered to be very reactive or very unreactive?
Alkali metals are considered to be very reactive because they readily lose their outermost electron to form ions. This makes them highly reactive with other substances.
What elements do no react with other elements?
Elements that are extremely unreactive include: Platinum (Pt), Gold (Au), Helium (He), Argon (Ar), Xenon (Xe), Krypton (Kr). These are unreactive because: Platinum and Gold are the bottom two elements in the metals Reactivity series. The rest are inert gases which are all unreactive.
