Answer:
d) copper, gold, silver
Explanation:
This question should be in the Chemistry section.
copper, gold, silver belong to the Group 11 (also known as the coinage metals) and share a few common characteristics which include:
They;
i) Occur in elemental and metallic form in nature and no extraction metallurgy is necessary to produce them
ii) are relatively inert
iii) are corrosion-resistant metals
iv) have low electrical resistivity
These elements were most likely the first three elements to be discovered as they occur naturally and are sometimes found close to the earth surface.
Roentgenium (Rg) is also categorized in the group 11, nonetheless it has not been shown to exhibit all of the characteristics of the other elements in the group.
