This is typical for a nonmetallic element: each atom is bonded to only a few other atoms. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. The forces holding the ions in place are strong enough that they cannot move past one another and therefore the crystal keeps its shape. Next is the gene. Atomic scale objects are too small to be seen even through the most powerful optical microscope. Does liquid water keep its shape? And this gives you a sense of scale, the width of hemoglobin is going to be about five nanometers. Seven millionths, seven seven millionths of a meter. has the potential to play an even greater role in prebiotic chemistry, providing an like a cell can be. When DNA gets coiled, it becomes smaller in size just in order to fit the nucleus of the cell. How did they measure the size of a water molecule? A red blood cell is 6-8 micrometers.
