10.90596, which is three decimal places away from the accepted relative elemental mass of 10.91046 for the Brenton element, and two decimal places away from the relative elemental mass of 10.88927 originally measured by Reiner, which is closer to the accepted value than the accepted value.

Without speaking, Reiner continued to conduct three experiments with the Bren's element in this bottle, and the obtained value was basically hovering around the first one, and it can be concluded that the Bren's element from the Antohar half-plane has a greater relative elemental mass than the Bren's element in the laboratory, and is closer to the accepted value.

"It's weird."

Xia Luo's eyes widened in surprise, and she repeatedly confirmed the numbers on the paper, for fear that she had read the wrong one.

Reiner carefully recorded the experimental data, and then took another vial, the Bleen element from the Gledia half-plane, and measured it, and the circle quickly gave a reading.

10.92779！

This is two decimal places away from the accepted value, and the value is much larger than all measurements.

Later, Reiner repeated the measurements with two other measuring circles, but the results were almost the same.

"It can be seen that the relative elemental mass of the Boren elements from different regions varies to varying degrees, which does not seem to be an error in the experiment."

Reiner noted in his notes that he then took a portion of the Chamberlen element from each of the three bottles, mixed it, and began to measure the relative elemental mass again.

This time the result is 10.90977, which is only 0.00069 away from the accepted value!

Excluding errors in the actual measurements, this can be considered almost equal to the accepted value.

"Why is this happening?"

Charlotte sat in her chair, puzzled, and now it seemed that only the crazy idea that the same element had different qualities could explain the problem.

But why is that?

If this is the case as to why the same element has different elemental masses, then it seems less convincing to arrange elements by their masses, and the laws of the elements are once again in the fog.

"It seems that when I measured it before, the elemental mass of the Burren element used by the Rainbow Tower was closer to 10.91046."

Until now, Reiner said, it was impossible to imagine that the same element would have different elemental masses, so it was natural to dismiss some measurements that were too different from the accepted values as experimental errors.

But his experiments proved that even the same element has different elemental qualities.

"Are there really isotopes too?"

Reiner secretly thought in his mind that isotopes are a common concept on Earth, referring to the same element with different atomic masses, and the essential reason for its appearance is that the number of neutrons contained in the nucleus of the atom is different, resulting in different relative atomic masses.

If there were isotopes, it is no wonder that Lord Stenion was puzzled by the inevitable error of arranging the elements solely on the basis of their relative masses.

Reiner did not feel the feedback of the world, according to previous experience and some related research, it is impossible to simply put forward a conjecture like now, he must actually find evidence of the existence of isotopes, and at the same time systematically summarize, and now the experiments of the Chamberen element only indirectly prove that the mass of the elements will be different, but did not find the reason.

To fully prove this idea, Reiner would probably have to find at least a pure isotope, such as tritium and deuterium.

"It's a bit tricky."

Reiner didn't have the financial resources to collect these elements of different qualities like a needle in a haystack, and on the other hand, the level of magic needed to isolate isotopes was far from what he was currently able to achieve.

In my memory, the separation of isotopes on Earth uses the movement of charged particles in a magnetic field, but the magic involved in this is obviously beyond the reach of a ring mage, unless Reiner finds someone to make these magic into corresponding magic circles, but that must be at least a mid-level level.

Of course, he could have written to Lord Stanion and told him about his experiments, and presumably it would not be easy for a legendary mage to create a magic isotope separation, but then Reiner would no longer be the first discoverer, and he would have received much less feedback.

As a mage, Reiner naturally has some selfish intentions.

In the end, he decided to collect information first, try to isolate the isotopes, and if he really couldn't do it, he would turn to the high-ranking mages of the mercury balance and sell his favor by the way.

"We'd better find a few more elements that have a similar situation, and make sure it's not the case of the Bren's element alone."

Reiner suggested that this was also evidence of isotopes, and that this work could also help him analyze them before he found a way to isolate them.

"Well, I've been measuring the elements in the lab all this time."

Xia Luo nodded, she felt as if she had touched a certain door, but she couldn't get into it, and the anxiety made her a little upset.

Goo –

However, an untimely stomach cry made the girl's face flush.

Reiner smiled and looked up at the window, it was already noon, and the two of them were so immersed in the experiment that they lost track of time, and the morning had passed.

"Let's go get something to eat, Charlotte."

Reiner suggested that he had eaten a simple slice of bread in the morning, and was now a little hungry.

"Uh-huh."

Xia Luo nodded vigorously, compared to Claire's appetite for food, Xia Luo is obviously not so exaggerated, but adolescent girls also need a lot of nutrients to develop, so they are also interested in eating.

The two packed up their lab equipment and left the lab, but as soon as they stepped down the tower, the alchemist brought a message.

"Someone came to visit me?"

Reiner frowned, he hadn't made a reservation recently, and he couldn't think of anyone who would come to him at this time, but Reiner nodded anyway, and then said to Xia Luo.

"Then Xia Luo, you should go to the cafeteria first, and I'll go see who it is."

"yes, okay."

Although Xia Luo felt a little regretful, she could only nod her head and leave alone.

Reiner made his way down the hallway to the reception room.

Here sat a man in a suit and gown, his face was delicate and handsome, his linen shawl hair was tied into a ponytail behind him, a little more gentle, and he wore a pair of rimless glasses on the bridge of his nose, quite scholarly.

When he saw Reiner, he immediately smiled, stretched out his hand to Reiner, and spoke, his voice a little shrill and high-pitched.

"Long time no see, Mr. Ian Gray."

"Uh...... Do we know each other? ”

Reiner had no impression of the man, and asked with some hesitation.

"Haha, I'm sorry, I'm sorry, I forgot Mr. Ian Grey that this is the first time you've seen me dressed like this."

The man then untied the ponytail at the back of his head, removed his glasses, fiddled with it for a moment, and then said.

"I'm Elise. Sophinet, the manager of the afternoon tea party. ”
