Question

which microscope is often used to view metal surfaces? scanning tunneling microscope transmission electron microscope scanning electron microscope compound light microscope

Explanation:

Scanning electron microscopes (SEMs) are designed to produce high-resolution images of the surface topography of solid samples, including metals, by scanning a focused electron beam across the surface and detecting emitted secondary electrons. Transmission electron microscopes require thin, transparent samples, compound light microscopes lack the resolution for detailed metal surface imaging, and scanning tunneling microscopes are more specialized for atomic-scale surface analysis of conductive materials, but SEM is the most commonly used for general metal surface viewing.
