What I especially want to emphasize are any superlatives of the
elements, i.e. , the chemical properties and the nuclear properties,
each element has which are unique, aside from the fact of the
uniqueness of atomic number. Please point out any superlatives which I
have overlooked. There are mistakes in these descriptions please notify
me of the mistakes.

Element 8, oxygen, O, is a colorless, odorless, tasteless gas. Atoms of
oxygen are some of the atoms which forms the basis of all life for it
is part of the DNA molecule.   Oxygen is the most common element found
on the Earth’s surface composing about 49% by weight and it forms about
21% of the Earth’s atmosphere by volume.  The human body is about 2/3
oxygen by mass. Water is 88.8% by mass oxygen. A thousand atoms of
"average" seawater (3.5% NaCl by mass) would contain about 330.9 atoms
of O, 661.7 atoms of H, and 3.7 atoms each of Na and Cl. Oxygen is
essential for respiration for all animals, and restored back to the air
by plants. After 5 minutes without oxygen our life would end.  Oxygen
is essential for all combustion.  Ozone which is O3 is of vital
importance in preventing harmful ultraviolet rays of the Sun from
reaching Earth.
