Hu - Hmolpedia
Some depictions of the symbol Hu short for the "human element", Hu being short for "human", 7E+9 short for 7 billion humans, the 2006 population of the humans, and the number 8 or 10 being the generalized periodic table element number location of the element that comprise one human, namely carbon 6, nitrogen 7, oxygen 8, or sometimes the number 10, the element number of Neon, is seen in advertisements, although, to note, neon is not part of the elemental composition of one human.
In symbols, Hu is a chemical letter (or chemical alphabet) stylized shorthand for one human, conceived as a “human element”, aka “The Human Element”, as Dow Chemical popularized the symbol in a series of 2006 launched commercials, or one human molecule, depending.

The following are related quotes:

“One of the first steps was a creative meeting at our agency during the “pitch process.” I walked into the meeting with a new element for the periodic table. . . not carbon, hydrogen or oxygen, but the Human Element. That pretty much put everything in motion. Including the Human Element on the Periodic Table of the Elements changed the way Dow looked at the world and the way the world looked at Dow. Every creative decision we made from that point on was filtered through the lens of the Human Element, and that’s what took us down a very non-science approach to science advertising.”
John Claxton (2009), on DraftFCB’s new marketing campaign for Dow [1]

The element number 08, in the original sketch, as shown above, symbolic of oxygen on the periodic table, seems to be an intuitive grasp at the premise that humans are "carbon-plus" types of elemental things, carbon being atomic number 6 on the periodic table; hence, the numbers 8, 9, and 10, often seen on mock-designs of the Hu element theme concept, a human is an elemental thing "above" element number 6.

The following is a Feb 2020 symbol made by Libb Thims, for new business cards, shown below representing the knowledge that humans are 26 element chemical species (26E), and that the current population is 7.8 billion or 8E times 10 to the power of 9, rounded up (correctly this should be a measure in hmol units, but his has not yet become a working concept):

The mass number 7E+09 is representative of the current population of humans, which in 2009 was 7,000,000,000 or 7 billion or 7 times 10 to the power of 9.
