The mineral copper (cu) is composed entirely of copper atoms. to which mineral group does copper belong?

The correct answer is native elements.

Explanation:

Rather than the free gases found in the atmosphere of the Earth, some twenty elements are found in nature in a pure or almost in a pure form, which is known as the native elements.  

The native elements are differentiated into three families, that is, semi-metals, metals, and non-metals. The most usual native metals that are featured by basic crystal compositions form the three groups, known as the gold group, comprising silver, gold, lead, and copper.  

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
