The Structure Of The Atom

The space between the protons and electrons of the atom is as wide as
the area marked on the above map.

thousandth of a millimetre. 18
At this point, we realise that there is a similarity between the largest
and the smallest spaces known in the universe. When we turn our eyes to
the stars, there again we see a void similar to that in the atoms. There are vo-
ids of billions of kilometres both between the stars and between the galaxies.
Yet, in both of these voids, an order that is beyond the understanding of hu-

Inside the Nucleus: Protons and Neutrons
Until 1932, it was thought that the nucleus only consisted of protons

and electrons. It was discovered then that there are not electrons but neut-
rons in the nucleus besides the protons. (The renowned scientist Chadwick
proved in 1932 the existence of neutrons in the nucleus and he was awarded
