Meet the principal

After sending a series of teaching materials to Principal Nathan Fisher who was far away in Rainbow Tower and giving a lot of suggestions, Reiner was waiting for feedback while starting his own research work.

The materials he asked Mr. Osborne to purchase were finally sent to Crescent College yesterday. Reiner couldn't wait to come to the laboratory early this morning, ready to continue his isotope research.

The experimental process was very simple. He purchased several identical elements from different planes to verify that the relative element quality of the same element would be different due to regional distribution and other reasons.

He first needs to find out whether the isotope phenomenon is universal in the world, rather than a unique attribute of the "Berran" element.

Reiner called Xia Luo, and the two worked in the laboratory for a whole day before finally measuring the relative elemental masses of the four elements purchased by Reiner.

Among them, the element "Sterner" collected from the four half-planes has four relative element qualities with large differences, and the "Carbon" element collected from the four half-planes has three different relative qualities. The other two elements "Plambo" and "Saffron" elements have two relatively different element masses.

There was not much error in the relative elemental masses of three elements, and Reiner also recorded them properly.

Experiments have proven that this phenomenon of the same element but different relative element masses exists not only in the "Berlen" element, but also in other elements, regardless of metallic elements or non-metallic elements.

Unfortunately, Reiner was never able to isolate pure isotopes or prove that there were indeed two particles with different relative elemental masses.

On the earth, isotopes are generally simply divided into stable isotopes and unstable isotopes. The difference lies in the length of the half-life, which is the normal time for radioactivity to decline. Generally speaking, isotopes with a half-life of more than ten years are called stable isotopes. Reiner is now Those that can measure obvious differences should also be stable isotopes.

Reiner could not remember clearly the theory required to separate isotopes. He vaguely knew that temperature or reaction speed could be used to separate isotopes. As for proving the existence of isotopes, perhaps a mass spectrometer could help.

However, the theory involved in the mass spectrometer is already the content of the mid-level mage, and Reiner cannot access it for the time being. You must know that the magic model of stable electric field and magnetic field not only requires five hundred academic points to redeem, but also has requirements for the user. Above the fourth ring, modifying it to the appearance that Reiner needs requires a corresponding level of magic. Reiner really couldn't figure it out on his own for a while.

Reiner decided to write the paper first and at least file it with the Rainbow Tower to protect his rights. As for how to prove the isotope, he had to continue to think of a way.

If Reiner's suggestion succeeds, and someone gets inspired after he publishes the paper and successfully separates the isotope, then Reiner himself can also get feedback from part of the world, and this wave will not be a loss.

Of course, the best case scenario is that Reiner extracts the isotope himself, but under the current circumstances, this hope is somewhat slim.

At night, Reiner sat at his desk, quill in hand, and began to write his paper.

"A hypothesis about the difference in relative element mass and its impact and discussion on the laws of elements".

"The relative elemental masses have been proposed for decades. Mages have made precise measurements of the relative elemental masses of common elements. However, I found in experiments that the relative elemental masses of several elements are significantly higher than the generally accepted values. An error that cannot be discarded. To this end, my assistant and I conducted experimental research and finally came to the following conclusion..."

Reiner recorded his experimental process in detail. He made detailed descriptions of the origin, measurement values, and errors of the five elements, which were authentic and credible. At the same time, Reiner also recorded the data of several other elements that had no measured errors. Recorded it in detail,

This is used to prove that there is no problem with the measurement array used in the experiment.

For these elements that have the same properties but different relative element masses, Reiner named them isotopes.

After writing this, he began to derive the laws of elements.

Reiner believes that the idea of ​​​​sorting by relative element mass is correct, but due to the presence of the isotopes mentioned above, there are omissions in Lord Lanchester Stannion's arrangement.

Mr. Stanion's element table has eight columns, which includes most mainstream elements, but some special elements still linger outside the table, and even if they are periodic, there are some forced approximation problems for elements in the same row.

In general, this original periodic table of elements still has many problems, and it cannot be regarded as truly reflecting the nature of "periodic".

Therefore, Reiner rearranged the table of elements arranged by Mr. Stanion.

He first used the familiar vertical column arrangement, placing elements with similar properties in one column. He swapped the positions of several elements with similar relative element masses due to isotopes, and reserved some vacancies for some elements with lively or special properties. similar elements.

"Good thing I don't have to do playing cards to sort them."

Reiner laughed at himself and said that Mr. Stanion must have received a certain amount of feedback from the world when he proposed periodicity. This time he is really standing on the shoulders of giants.

After finishing the periodic table of elements, Reiner simply made bold assumptions and predicted the existence of some elements.

Reiner doesn't know if there are inert gases in this world, but at present, there is no such element in Mr. Stanion's element list. This kind of element itself is not easy to combine with other elements. Most of them exist in nature as simple substances and are difficult to combine. be found.

He predicted that between the element "Florin" and the element "Thodeon", there should be an extremely inactive element. This element should be a gas. Reiner made the prediction based on the properties of the two elements. Several predictions about this gas were made, and these and several other speculations were recorded as the content of the final chapter.

It was already late at night when he finished writing these papers. Reiner put down his pen. There seemed to be a little ripples in his heart, but he remained still as if he was still short of breath.

Just like the deepest night, in the silence, a storm that could sweep the world is brewing.

He shook his head, still thinking about why the routine little guy didn't visit today, when he heard a cat meowing from the window sill.

But when Reiner poked his head out, he found that the tiger-striped kitten was not on the window sill, but on the ground downstairs.

Next to the kitten, a girl was squatting, feeding it with food. Judging from the school uniform, she must be a student of Crescent College.

"Hey, who is this?"

Reiner thought that the students should have turned off the lights and gone to bed by now.
