Question
What is the arrangement of atoms in elements ?
Solution
Atoms are very small atoms, they are smaller than anything that we can imagine or compare with. More than millions of atoms when stacked would make a layer barely as thichk as a sheet of paper. Nowdays, It is possible to take in depth photographs of the surfaces of the elements. The surface images of silicon with a scanning tunneling microscope (STM) shows that the silicon atoms are arranged in a regular pattern.
