Jan, read this and don't be so ignorant. Many scientists were trying to
find the charge of electrons since 1897, but historians CANCELED THEM
(also due to political struggles, which are getting worse 120 years
after).

Sigh, so you succeeded in misunderstanding that too.
Planck didn't do any calculations with electrons,
or with the classical electon radius.

What Planck did do was to obtain a value for Avogadro's number

All this was highly speculative theory at the time,

There was little reason for singling out Planck.

However, Arrhenius had met Planck, they had become great friends,

Arrhenius failed to convince his collegues of course.

Jan (man or woman): I'm tired of you behaving as A FULL RETARDED, an
imbecile, a liar, A DECEIVER (as any relativist) and (mainly) A
CHARLATAN!.
 
You don't know even how to do a little research on Google. Instead, you
write PURE CRAP to justify your idiotic posture, imbecile know-it-all!
 
I'll try to help you TO OVERCOME your cretinism, just with one paper:
 
Max Planck's Determination of the Avogadro Constant
 
https://www.scielo.br/j/rbef/a/XMkjKHvTWdsTF9k5HF6Vzwv/

There you are there at last, and I only had to tell you a few times.
Planck did nothing about electrons, he found (yet another) way
to determine Avogadro's number.

EXCERPT (READ THIS VERY CAREFULLY, IDIOT Jan):
---------------------------------------------------------

Always nice and to the point, aren't you?
 

8. The Electronic Charge
 
Planck does not mention a reference for the Faraday constant used in his
work. He wrote e = ?w, or in modern language, N?e = F, uses
? = 3.2223E-05 esu mol^-1 = 96603 C mol^-1 with no reference, to
calculate the electronic charge,
 
                e = ?w = 4.69E-10 esu
 
This is also an excellent result since 4.69E-10 esu = 1.5644E-19 C, with
an error of 3%, if compared with the tabulated value, 1.602E-19 C. The
result was compared to the previous result, 2.186E-19 C, as obtained by
J.J. Thomson. The Faraday constant used by Planck was also very precise
for the year 1900, with an error of 0.1%. The accepted value today is
F= 96485 C mol^-1.

I'll put down the elementary logic -> Avogadro' of it once again:
Planck's radiation law -> Boltzmann's constabnt k
-> + Gas constant - > Avogadro's number _> + Faraday -> electron charge.

Faraday's constant was well established by the end of XIX century. The
precise measurement of the Faraday's constant was made by Lord Rayleigh
and Mrs. H. Sidgwick, in the paper On the electro-chemical equivalent of
silver, at Phil. Trans., page 411, in 1884, [25]. On page 439 it is
mentioned that they obtained m = 11.794E-03 g as the amount of silver
deposited at the electrodes. Therefore,
 
                 F = 96.544 Cmol^-1
 
with an impressive error of 0.07 %. Planck chose to use F=96603 C mol-1,
but this will affect his value of electronic charge at the third
significant place. He would have obtained e = 1.5635E-19 C instead.
 
The first measurement of the electronic charge goes back to 1874 and was
made by George Johnstone Stony, on the paper, On the Physical Units of
Nature. Phil. Mag. 11,384(1881). The value appears on page 388 of the
paper. Several measurements were performed after this. Planck used the
most precise value at his time, as made by J.J. Thomson.
----------------------------------------------------------------

Sigh. Thomson did not determine the electron charge for his experiment.
He determined e/m.

Do you understand now WHY I call you A FUCKING RETARDED, CHARLATAN AND
IGNORANT, Jan?
 
 
You are much worse than the above simplistic labels. You have NO CURE
for your stupidity, your FRAUDULENT WAY to write posts, and your TOTAL
LACK OF ABILITIES TO HIDE THAT YOU'RE A FUCKING RETARDED (VERY).
 
I hope you may have learned a lesson, nanosecJan.
 
As for me, you HAVE NO CURE. You're a complete idiot, as it correspond
to a relativist.
 
Did you see what means to LEARN ABOUT HISTORY OF PHYSICS? No Avogrado
involved in his calculations. Read the entire paper, and you'll be
SURPRISED about how much was known about physics constants by 1900.

Nothing was known 'for certain' about Avogadro's constant in 1900.
In fact, there was a whole school of physicists
(positivists, energists, etc. following for example Ernst Mach)
who denied the real existence of atoms,
and hence that there was any physical meaning to Avogadros number.
They considered it to be merely a convenient fiction,
useful for the purpose of doing certain calculations only.
But their position was gradually being worn down by many independent
and converging determinations of Avogadro's number.
(for example also Einstein 1905)
Chemists of course had no doubt about the real existence of atoms.

So now that I have clued you in you may understand what all the ado
about the 1908 Nobel prize was about.
Arrhenius (himself a chemist) proposed both Planck (physics)
and Rutherford (chemistry) for two simultaneous Nobel prizes,
both relating directly to Avogadro's number.
He hoped to kill off all of that 'energist' nonsense
with one fell swoop, using Nobel's double weight.
But his little plot failed.
Planck's work was seen as too speculative by his collegues,
and only Rutherford got the prize.
