help me answer the question below.

The chemical element thorium [is] mapped [by a GRS], with higher

concentrations shown in yellow/orange/red in the left-hand side image shown on the right.

the colour of growing foliage, as well as other plant cells containing chlorophy is called green, or green radiation.

“Grain size varies from 98 to 530 lm with an average of *150 lm. Minor [elements] oxidation [from an iron–nickel–chromium–cobalt–phosphorus alloy] is evidenced by the presence of a light brown and blue surface layer composed of very fine-grained (<1 lm) crystals on the surface. The oxidation of minor elements in metallic alloys in the early solar system” is indicated to possess at instances a blue surface layer.

The orange system [in orange astronomy] is a number of emission lines very close together forming a band in the orange portion of the visible spectrum. These lines are usually associated with particular molecular species, including ScO, YO, and TiO

the analysis of material samples to gain an understanding of their chemical composition and structure. Analytical chemistry incorporates standardized experimental methods in chemistry. These methods may be used in all subdisciplines of chemistry, excluding purely theoretical chemistry.
