Greetings, Mister Principal: Atomic model

There is still a week before departure, so Reiner naturally has no time to spare.

The day after he invited Claire to travel with him, he came to the laboratory.

Reiner quickly arranged the magic circle that he had redeemed from the Magic Association using academic points.

The three particle generation arrays each require thirty academic points. This is different from Fina's father's original array, but an optimized array that has been optimized and improved by several mages. It can produce pure particles without impurities. Particle flow is safe and reliable and will not affect the user. Due to the standard magic stone function, usually a three-ring mage can control it independently, and Reiner can naturally use it.

A piece of paper floated next to Reiner, with a sketch of the experiment he designed last night on it.

He first arranged a disk, placed a thin piece of gold foil in the middle of the disk, and then placed particles on one side of the disk that could produce elemental Helios particles with a relative elemental mass of about 4. The flow array has a microscope arranged around the disk. The disk is surrounded by a receiving screen. If the Helios particle hits the receiving screen, a light spot will be left. This microscope can surround the disk. Rotate enough to observe Helios particles coming from all directions.

In order to prevent interference, the entire experimental device was covered by a vacuum glass cover, and Reiner could control the rotation of the microscope through the mechanism.

After assembling the experimental device and debugging it, Reiner officially started the experiment.

He activated the particle generation array, a burst of fluorescence flashed, and the invisible particle stream began to gradually surge, hitting the gold foil.

The particle flow release frequency set by Reiner was very low. After about ten minutes, he stopped the operation of the particle generation array, then turned the microscope to count the landing points of the Hilios particles that fell on the receiving screen.

If you follow Alterac's opinion, the deflection angle of the Xilios particles in this experiment should be very small.

If an electron is hit, based on the mass ratio of the two, the impact of the electron on the Helios particle is minimal and can be ignored.

If an atom is hit, then the positive charges on both sides of the atom cancel each other out, and the Helios particles will have basically no effect.

So, according to the cake-and-raisin model, the Helios particles should have been barely deflected in this experiment and concentrated on the other side of the gold foil.

However, when Reiner finished the statistics, he found that although most of the Hilios particles were concentrated on the receiving screen opposite the particle generation array, there were still a small number of Hilios particles. The phenomenon of large-angle deflection occurred. The deflection angle of some Helios particles exceeded 90 degrees, and some even experienced 180-degree reflections!

This goes against the atomic model proposed by Lord Alterac.

Leiner repeated the experiment twice more and obtained similar results. Then he came to the table on the other side, leaned over and started writing.

"...According to experimental phenomena, most of the mass and charge of atoms should be concentrated in a very small space. Atoms are not like cakes studded with raisins, but are composed of a very small nucleus. and the electrons surrounding it."

Only when the mass of the entire atom is concentrated in a small area, experimental phenomena can be explained:

Most of the Helios particles pass through the gaps between atomic nuclei, and even if they hit electrons, they have no effect at all.

A small number of Hilios particles passed through the area close to the atomic nucleus and were repelled by the positive charge, which affected the trajectory of the movement and caused deflection. The angle of deflection increased as the Hilios particles got closer and closer to the atomic nucleus. And getting bigger and bigger.

Some of the Helios particles happened to hit the nucleus and were deflected nearly 180 degrees.

Reiner called this atomic model a nuclear model. He then began to calculate and estimate based on the ratio of Helios particles at various angles on the receiving screen. Finally, he found that compared with the entire atom, the volume of the nucleus is less than One ten thousandth of it, if the atom is compared to a huge square, then the nucleus is an egg in the middle of the square.

He stopped writing and breathed a sigh of relief.

Reiner didn't end there. He thought about it and wrote down some conjectures at the end:

The first conjecture is that according to the periodic law of elements, although the nuclear charges of elements with similar properties are different, they must have certain characteristics that are similar. Reiner guessed that it is the electron distribution in the outer layer, because according to the alchemical reaction , some elements always lose the same number of electrons during reactions, which shows that the electrons outside the nucleus are not completely equivalent, and these electrons are different.

The second conjecture is that the atomic nucleus may not be the smallest particle, because the nuclear charges and relative element masses of the nuclei of different elements are different, as well as the existence of isotopes and the observation by mages that radioactive substances are releasing radioactive materials. The phenomenon of Rios particles transforming into another element after flowing.

Leiner conjectured that there may be a positively charged particle and an uncharged particle. These two particles of the same mass together constitute the atomic nucleus. In this way, every element or even every element can be combined. The theory that isotopes all occupy one type of particle is simplified into various atomic nuclei composed of different numbers of two types of particles.

He called the charged particles protons and the uncharged particles neutrons.

Writing these two conjectures, Reiner sighed slightly.

With his current strength and the level of magic he has been exposed to, he has not been able to verify these two conjectures. Therefore, he does not plan to write these two conjectures into the paper, but retains a trace of selfishness.

Raising his head, it was already afternoon. Reiner realized that he had not eaten lunch yet, and his stomach seemed to have forgotten his hunger before, and it was only now that he began to protest.

Reiner hurriedly packed up the experimental equipment, put away his notes, hurried to the cafeteria, took a simple meal and ate it happily.

After a full meal, he returned to his office, ready to continue reading "Alchemy" which he had only read the table of contents once yesterday.

But when he opened the door, he found that the tiger-striped kitten was already squatting on Reiner's desk, licking his paws, looking quite contented.

“I don’t have anything to eat. ~IndoMTL.com~ Reiner shrugged, put the notes in his arms on the corner of his desk, and gently scratched the kitten’s head.

"I'm not here to eat today, meow."

"Then what are you here for?"

Reiner asked, and then, after about ten seconds, he suddenly came back to his senses and looked at the tiger-striped kitten rubbing his palm in surprise.

"You...you spoke?"

He looked around to make sure that he was not affected by any illusions. He subconsciously took a half step back and stared at the kitten.

"Reintroduce yourself."

The kitten stopped and looked at Reiner with a pair of amber eyes.

"You can call me Lady Freya."
