Astudent says that all pure substances are elements. do you agree? why or why not? question 14 options: i agree. pure substances include only single atoms made of one element. i disagree. elements are not pure substances. all pure substances include only molecules and compounds, which are more complex. i disagree. elements form all pure substances, but some pure substances include elements bonded together to form molecules and compounds. i disagree. all pure substances are also mixtures.

yes i m agree with that Pure substances include only single atoms made of one element.

in chemistry , a pure substance that has only one kind of atom and cannot be broken into two or more simpler substance by physical or chemical means is an element . for ex. gold , silver , iron etc

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
