Alchemical Elements, Days of the Week, and Visible Planets

The Ancient Secret of Sevens:
Alchemical Elements, Days of the Week, and Visible Planets

Have you ever wondered why the 7 Days of the Week appear in a certain order?
First of all, our ancient seers knew the speed of the 7 visible planets, because they arranged them in the shape of a Heptagon or 7-sided polygon shape (shown in red).
Start with the Moon, which appears to move the fastest, and move upwards and towards the left to Mercury then Venus, then Sun, then Mars, then Jupiter and then Saturn.
To get the order of the Days of the Week that we all know, again starting with Monday the Moon, travel upwards towards your right to get to Tuesday Mars (the green lines) and viola, you create the 7-Pointed Star or Heptagram. That is why each day of the week corresponds to a planetary energy:

The Moon (Monday), Mars (Tuesday), Mercury (Wednesday), Jupiter (Thursday), Venus (Friday), Saturn (Saturday), the Sun (Sunday).
Then there is more science to this cosmogram:
Our Alchemist forbears even knew the Atomic Numbers (AN) and therefore the Atomic Weight of the metals that correspond to each planet according to this pattern of the days of the week, to form another form of the Heptagram Star shown in blue.
Start with the lightest one: Iron (AN=26, relating to Mars and Tuesday, aka Fe, = Atomic Weight of 56), then Copper (AN=29 = Venus = Friday, aka Cu = Atomic Weight of 64), then Silver (AN=47 = Moon = Monday = Atomic Weight of 108 aka Ag), then Tin (AN=50 = Jupiter = Thursday = Atomic Weight of 119 aka Sn), then Gold (AN=79 = Sun = Sunday = Atomic Weight of 197 aka Au), then Mercury (AN=80 = Mercury = Wednesday, = Atomic Weight of 201 aka Hg), then finally Lead (AN=82 = Saturn = Saturday = Atomic Weight of 207 aka Pb).
Another Heptagon appears (in light blue) when we consider the electrical conductivity sequence around the outside starting with lead.
The orbital motion of the planet correlates in sequence with its corresponding metal’s conductivity. The slower a planet moves, the less able its corresponding metal is to conduct electricity!
All these westernized correspondences appear only in the works of western Alchemy, surprisingly, it does not appear in any form in the Vedic knowledge or otherwise cultures!

In the Kybalion (A Study of The Hermetic Philosophy of Ancient Egypt and Greece by 3 Initiates), it says:
“The Principles of Truth are Seven; he who knows these, understandingly, possesses the Magic Key before whose touch all the Doors of the Temple fly open.”
