Describe how valence electrons from these elements behave when forming metallic bonds:

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.

thats a little if u want the answer just look it up on google thats what i do haha : )
