Periodic Table: The Composition of the Sun II.

Visualizing the chemical composition of the Sun's photosphere, which is possible to measure mainly through spectroscopy, is difficult, because it is mostly made of hydrogen (73.7%) and helium (24.9%) by mass, 92% and 7.8% by the number of atoms respectively.


Here, instead of showing it in a logarithm scale, I chose to scale the volume of each sphere according to the mass each element relative to the total mass. This way it is still possible to show the least abundant elements compared to hydrogen.


The mass of each element in the Sun's photosphere is printed in the bottom right corner in parts per billion by mass.
