Atomic arrangement in 3D

Atom Arrangement In 1D, 2D And 3D|Voids|Hexagonal Close Packing|Cubic Close Packing|OMR

Fraction of empty space in ABAB type arrangement in 3D

Most metallic element has the following electron arrangement in its atom is

Evidence for the electron arrangement in atoms has been obtained primarily from the study of :

An element A having molar mass of 100 g mol^(-1) crystallises in AAA....type of packing in 3D with HCP arrangement in each of layer.If the radius of atom is (10)/(sqrt(3))Å then find out the density of the element (N_(A)=6times10^(23) atom/mole)

The spatial arrangement of atoms that characterises a particular stereoisomers is called.
