Hydrogen atom

The hydrogen atom (H) is the smallest particle in matter: it has a diameter of 53 picometers (pm=10E-12 m), with a mass of 1.66 yoptograms (yg =10E-24 grams).

The largest atom is that of Francium (Fr) with a diameter of 520 picometers (pm=10E-12 m) with an atomic mass of 370 yoptograms (yg =10E-24 grams).

Francio has a diameter about 10 times larger than hydrogen and an atomic mass about 223 times larger than hydrogen.

The human eye can see at the limit 6-29 micrometers (10E-6 m) and estimate a weight of a few micrograms (10E-6 g). For example, 1 g of water (H2O) contains about 3.3428*10E22 molecules.

The hydrogen atom is composed of a circumscribed nucleus containing a neutron and a proton with a positive electric charge of +1.6022*10E-19 C (Coulomb – unit of measurement of electric charge). Around the nucleus, at an average distance of about 4.29*10E-5 microns, an electron with a negative electric charge of -1.6022*10E-19 C moves on the surface of a sphere. As a whole, the hydrogen atom is electrically neutral. However, the relative motion of the electron, in the outer shell, relative to the nucleus results in an electromagnetic field. The size of the nucleus (neutron and proton) and that of the electron is very small, as is the size of the atom. The volume of space within the atom is represented by an “empty” space; In other words, it can be said that the small volume of the hydrogen atom is mainly made up of an “empty” volume and only a very small part is represented by the mass of the neutron + the proton and + the electron. To put it simply, the hydrogen atom, as is true for all other atoms, the “vacuum” prevails dimensionally over the material mass.

Fun fact: the human being with an average mass of about 70 kg is estimated to be composed of about 15 billion of billion atoms (15*10E-18 atoms). The average volume occupied by a human body is 72 liters. Taking into account that atoms are essentially made up of “vacuum”, we can estimate that the human body is occupied by only one millionth of a millionth (10E-12) of solid matter. Even the solid matter that makes up the Earth and the Universe are predominantly made up of empty spaces.
