Which choice represents a group of elements with common characteristics? a oxygen hydrogen lithium b silver iodine helium c copper oxygen silver d copper gold silver

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.

there were three types of british colonies: royal, proprietary, and self-governing. each type had its own characteristics. proprietary colonies, such as pennsylvania, maryland, and delaware, were basically land grants from the british government.

hope this : )
