I do not understand "the chemical formula of Magnesium is Hydrogen & Oxygen." Magnesium is an element. It doesn't have a chemical formula.

Mg has atomic number 12.
Oxygen atomic number 8, Hydrogen atomic number 1.
Total number of protons in an H2O water molecule = 8 + 1 + 1 = 10

It is abundant in the universe, in the earth, and in the body.
In biology it is essential in 300+ enzymes.
It is essential in photosynthesis.

I conclude that you are not talking chemistry, but rather metaphysics or alchemy.

Does matter vibrate or interact with aether? Answer has to be yes. I can't prove it. Seems intuitively obvious. Assuming it's true that mind is structured aether, our material body's nervous system interfaces with our non-material mind.

Magnesium is highly reactive and forms all sorts of chemical compounds.
"Magnesium forms a variety of compounds important to industry and biology, including magnesium carbonate, magnesium chloride, magnesium citrate, magnesium hydroxide (milk of magnesia), magnesium oxide, magnesium sulfate, and magnesium sulfate heptahydrate (Epsom salts)."

The chemical formula for Magnesium Hydroxide (Milk of Magnesia) is Mg(OH)2. One Mg atom bonded to two hydroxide radicals. Mg (12 protons) + 2 x O (2 x 8 protons) + 2 x H (2 x 1 proton). A total number of 30 protons in 1 Mg(OH)2 molecule. I don't know why we are counting protons, maybe we're not?

I don't know a reason for making an analogy between a musical octave and chemistry. Not disputing it, just not understanding why. An octave is a doubling of frequency, containing 12 semitones. One semitone being the twelfth root of 2. All the intervals can be expressed as ratios of integers. E.g. 1/2 and 2/1 are octaves. 2/3 and 3/2 are fifths. 3/4 and 4/3 are fourths. etc.

This I know, but have never worked out WHY it is so. When I tuned pianos I used circle of 5ths going both directions up and down from A with just a little tiny bit of adjustment by ear by playing chords along the way, because if you tune just 5th --> 5th --> 5th --> etc. you will end up off by a little when you get back to A.
