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.

the exclusive possession or control of the supply or trade in a commodity or service.

1. yes it was the new deal introduced lots of regulations to workers, such as the national labour relations act of 1935 which workers to form unions and protected the members from other laws as well as forcing businesses to listen to the unions and their workers

3. yes it did bring some relief to those who were willing and able to work and it assisted in terms of creating new and strengthening existing infrastructure.
