1.	Surface is usually more than _____ atomic layer deep and is a region of ________ atomic potentials.(a) One, uniform(b) One, non-uniform(c) Two, uniform(d) Two, non-uniformI had been asked this question during an internship interview.This interesting question is from Surface Spectroscopic Techniques in section Electron and Ion Spectrometers of Analytical Instrumentation
Answer» Correct option is (b) One, non-uniform Explanation: Surface is more than one ATOMIC LAYER deep and is a region of non-uniform atomic POTENTIALS. The outermost layer of atoms is CALLED a surface.
