Introduction The carbon family, Group 14 in the p-block, contains carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). Each of these elements has only two electrons in its outermost p orbital: each has the electron configuration ns 2 np 2..
Allotropes of Carbon | Introduction to Chemistry
Allotropy is the property of some chemical elements to exist in two or more different forms, or allotropes, when found in nature. There are several allotropes of carbon. Allotropes of Carbon Allotropes of carbon: a) Diamond, b) Graphite, c) Lonsdaleite, d) C60 (Buckminsterfullerene or buckyball), e) C540, f) C70, g) Amorphous carbon, and h) single-walled carbon nanotube, or buckytube.

Practical Appliion of X-Ray Diffraction Imaging
The silicon crystal served as both a monochromator of K a and possibly K b wavelengths, and a beam expander,resulting in an x-ray beam of approximate dimensions 6 cm high by 2 cm wide. A crystal specimen of interest was mounted on a Newport rotation stage and placed in the path of the monochromated and expanded x-ray beam.
