Glossary terms about Atomic number

Atomic number (Z)
The number of protons, and also electrons, that the atoms of an element contain. In the Periodic Table of the Elements, elements are arranged in order of increasing atomic number.

Generating an image
This coating is applied for two main reasons: (1) Non-conductive specimens are often coated to reduce surface charging that can block the path of SE and cause distortion of signal level and image form; and (2) Low atomic number (Z) specimens (e. 
Images from electrons
Image from secondary electrons: high-resolution (InLens SE detector) Gold nanoparticles. (Topographical and morphological information.) Image from backscattered electrons Mineral sand: lighter grains have higher average atomic number
Introduction - aims and learning outcomes
For example, specimens such as metals with a high atomic number (Z) produce a high yield of electrons and achieve a higher useful magnification than low Z samples (e. 
Sample preparation
For BSE imaging carbon coating should be chosen instead of metal coating because a metal coat would detrimentally affect the imaging of average atomic number
Variable Pressure or Low Vacuum scanning electron microscopy (LVSEM)
Backscattered electron imaging (BSE) of nonconductive, uncoated samples can provide information about composition via the contrast of the image: whiter regions have a higher average atomic number than darker regions. 
What is resolution?
