metals that are in their true form and have not been combined with other metals to produce an alloy
helium, copper, neon, argon
You would call them pure metals or simply elements, when a metal is mixed with another, usually for dual properties (e.g steel and aluminum alloy - in planes because it is light and strong) it is called an Alloy.
the majority of metals are found combined with other elements in nature. Only a few are found uncombined- the best known example is gold.
Copper (Cu), silver (Ag), gold (Au) ....Osmium (Os) is also found in nature as an uncombined element sometimes. Rhodium (Rh) can occur as a rare deposit in uncombined form, for example in Montana, USA.Platinum (Pt) nuggets also occur naturally in the uncombined state.Tellurium (Te) is sometimes found in its native (elemental) form.Chromium (Cr), lead (Pb) and mercury (Hg) have also been found in uncombined form, but this is extremely rare.

They are dangerous because in their uncombined forms they are highly reactive. Hope this helped ^,..,^
Reactivity series is a list of metals arranged in the order of their decreasing activities.
They are very reactive.They cannot be found uncombined.

There are nothing uncombined. They are forming compounds inn nature.
Because these metals are very reactive and readily form compounds.

Yes, gold was found thousands of years ago because it is often found in nature in its pure form as nuggets or grains, rather than combined with other elements. This made it easily visible and recognizable to ancient peoples as a valuable and desirable material.
