hydrogen

“Recognize that the very molecules that make up your body, the atoms that construct the molecules, are traceable to the crucibles that were once the centers of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. So that we are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically. That’s kinda cool! That makes me smile and I actually feel quite large at the end of that. It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us.”

ATOMS and MOLECULES Rendered in 3D

Depiction of the electron orbitals is based on [the following].

  • Electrons travel at relativistic speeds and would appear as streaks of light if they were visible at all.
  • Quantum mechanics proposes that the exact location and speed of each electron is determined by probability.
  • So, an almost electrostatic lightning storm over the surface of each orbital is a good representation of what the electrons actually do,
  • along with the fact that free electrons escape from and are captured by atoms all the time

Hydrogen – diatomic hydrogen (H2).

Neon – a stable nuclear arrangement of ten protons and ten neutrons and thus easy to portray as the twenty vertices of a regular dodecahedron. 

Carbon – a single Carbon 12 atom. 

Water – with electron orbital wave functions and free electrons.

Diamond

In general, the fewer inclusions within a diamond, the greater its desirability. With the use of fiber optic illumination, this stellate cloud becomes bright and beautiful with a stunning symmetrical design. When you’re looking to wish upon a star, you might consider a diamond with a bright and beautiful inclusion such as this.

Scientists have developed a procedure to cheaply create hydrogen for fuel and oxygen gas

By Mark Shwartz -

Stanford University scientists have invented a low-cost water splitter that uses a single catalyst to produce both hydrogen and oxygen gas 24 hours a day, seven days a week.

The device, described in a study published June 23 in Nature Communications, could provide a renewable source of clean-burning hydrogen fuel for transportation and industry.

“We have developed a low-voltage, single-catalyst water splitter that continuously generates hydrogen and oxygen for more than 200 hours, an exciting world-record performance,” said study co-author Yi Cui, an associate professor of materials science and engineering at Stanford and of photon science at the SLAC National Accelerator Laboratory.
