3Element - HmolpediaH10Hydrogen1
In chemistry, hydrogen, symbol H, atomic number 1, is a nonmetallic element, row one of the periodic table, the third the most abundant element in the person, comprising 10 percent by mass of the average human molecule.

Hydrogen is the smallest element, is an atom comprised of one proton bound, via the electromagnetic force, via the exchange force of photons, to one electron.

All elements are built from the components of the hydrogen atom. [1]

Hydrogen is the third most abundant element in the human molecule, comprising 10% of the mass of the human.

Hydrogen accounts for 88% of the atoms in the universe.

Elective affinities problem
The hmolscience view of the chemical synthesis of humans from hydrogen atom precursors, according to which—in the defunct theory of life view of things—humans are 26-element molecules that have been synthesized or metamorphosized over time, in a transformation process that began, according to big bang theory, 13.7 billion years ago, and, once the the sun ignited, some 4.5 billion years ago (see: elective affinities problem).
Hydrogen molecule vs. human molecule
The comparison of the hydrogen molecule H2 (a two-atom structure) to the human molecule Mx of Fy (a 10E27 atom structure) is a frequently-made comparison in hmolscience debates and discussions.

In 1988, Canadian zoologist Daniel Brooks and American systems theorist Edward Wiley, in their chapter subsection on “metaphysics of individuality”, give the following blurring statement in comparing the human or rather human molecule as contrasted with the hydrogen molecule: [2]

“A hydrogen molecule is the thing which reacts. Homo sapiens and other particular species are the things which evolve. Such individuals differ from classes by having particular origins in time and space. They may disappear or change into other things.”

This, however, is an artificial divide. The resolution of the divide requires a reinterpretation or rather reformulation of evolution theory in chemical thermodynamic terms, which is a nearly virgin subject.

Quotes
The following are related quotes:

Hydrogen is a light, odorless gas, which, given enough time, turns into people.”
Edward Harrison (c.1990) Publication (Ѻ); cited (Ѻ) by John Wiley (1995) in “Phenomena, Comments and Notes” (Ѻ); cited (Ѻ) by David Christian (2004) in: Maps of Time

“Why should a group of simple, stable compounds of carbon (C), hydrogen (H), oxygen (O), and nitrogen (N), 'struggle' for billions of years to organize themselves into a professor of chemistry? What's the motive?”
Robert Pirsig (1991), Lila: an Inquiry into Morals
