Under Lin En's order, Alok and others who were waiting in the audience quickly brought up the props for the experiment.

It was very simple, with only three things in total! A palm-sized lead box and a ring-shaped detection device.

The last piece of gold foil was only 0.1 microns wide! It took Lin En a whole day to make this thing. If he hadn't become a great wizard, it would be impossible to achieve such precision with the current craftsmanship...

After all the experimental equipment was prepared, Lin En didn't keep the secret any longer. He looked around at the wizards in the conference room and spoke solemnly.

"Everyone, the atomic model hypotheses you just proposed are all very interesting, but whether a theoretical doctrine conforms to reality still needs to be proven by experiments!"

"Of course!" Anthony nodded.

He was very confident in his elemental purple fruit model, but he had to admit that some of the ideas proposed by the congressmen were also very interesting.

For example, the great fire wizard Adela believed that the electrons inside the elements were arranged in a way that positive and negative charges were intertwined, so they could combine tightly and not repel each other due to like charges, thus coming together to form a solid atom.

In addition, there are more than ten different theories such as water droplet theory, external dispersion theory, element solidity theory, etc., all of which have a certain degree of rationality...

However, how to verify it is undoubtedly the most troublesome problem for all wizards who propose elemental models.

Because the elements themselves are so tiny, they have tried countless ways to break them but have been unable to do so. Some wizards have even used the principles of convex and concave mirrors to develop ultra-high-power microscopic magic, but they still can't see anything. So they are very curious about what means the Magic Star will use to verify this.

Lin En had no intention of keeping the audience in suspense and quickly began to explain.

Alpha particles are scattered from the interior of the radium element, which means that their volume is much smaller than many elements, their speed is extremely fast, and more importantly, they have the ability to escape the control of the element.

"According to my calculations, the speed of alpha particles is about 20,000 kilometers per second..." Lin En began to speak.

"Twenty thousand kilometers..." Sanchez smacked his lips in amazement, shocked by this outrageous data.

Although they have already measured the even more outrageous speed of light, this speed of 10,000 kilometers per second is still beyond their reach...

Anthony was also extremely surprised. Thinking back to the moment in the Cloud Chamber, the surge of the Mist Track was so fast that even these great wizards could not react. This was enough to prove that Lin En was not exaggerating! "So you are going to use this new particle to impact and destroy the outer shell of the element?" Harov quickly thought of this.

Generally speaking, the faster an object is, the greater its destructive power. The advantage of the Alpha element is that it is small enough and may be able to knock open the outer shell of the element and cause it to break.

"No, I think the atom doesn't have an outer shell. Everything about it is exposed..." Lynn shook his head and said seriously.

"How is that possible?" Vittorio frowned and refuted. "All elements are in motion all the time. If there is no outer shell to protect it, after millions of years, wouldn't the things inside have been thrown out long ago..."

In their imagination, elements should be in the shape of a sphere, wrapped in an extremely hard shell, so as to protect the internal substances from damage over the years.

Facing everyone's questioning gazes, Lin En smiled and asked back, "Compound elements also don't have shells, so can't they survive for a long time?"

According to the existing theories in the Wizarding Land, the reason why those composite elements can stick together firmly is that they are connected by something called elemental co-bonds, so they will not easily separate. In fact, to put it bluntly, it is also a chemical bond, but the name is different between the two worlds.

Hearing this, Vittorio and the others were stunned for a moment, and then they began to wonder whether there might be a similar force inside the elements that could firmly bind the matter inside.

Lynn did not continue with his lengthy explanation. Words are not enough, facts are the best evidence.

During this delay, Alok and others have already set up the experimental table. In fact, they just cast magic to make the gold foil float in the center of the detection device.

Then, the lead box is placed facing the gold foil, a small hole is opened at the front end, and a certain amount of radium element is placed inside. Since lead can effectively protect against radiation, alpha particles will only be emitted from the small hole in the lead box, forming a beam of high-energy particle rays that continuously hit the gold foil.

The gold foil is surrounded by a ring-shaped detection device covered with fluorescent paint. It will glow when it comes into contact with alpha particles, thereby determining the movement of the particles.

As for why gold is used, it is of course because this thing has extremely strong extensibility. Only 1 gram of natural gold can be stretched into a gold wire several kilometers long. This can ensure that the rays pass through a limited number of elements in a straight line, reducing interference to a minimum...

After roughly explaining the experimental process, Lynn opened the hole in the lead box, and a beam of rays invisible to the naked eye immediately hit the gold foil.

Both alpha particles and gold atoms are extremely small and cannot be seen with the naked eye, but wizards naturally have their own ways. In particular, great wizards have strong perception abilities that allow them to detect subtle changes at the atomic level.

After the field was expanded, the entire piece of gold foil took on a different look in their eyes. The gold elements were arranged in an orderly manner, blocking the way ahead like a solid wall.

However, this wall was not as strong as they imagined, because small dots soon lit up on the detection device at the back, which meant that the alpha particles passed directly through the gold foil and came into contact with the fluorescent material at the back.

"It actually went straight through!" Harof murmured softly. The position of the light spot was directly facing the direction of the hole in the lead box, without the slightest deviation.

Anthony, who also discovered this, couldn't help but frown. This was not what he had imagined.

You have to know that alpha particles also have magnetic field reactions, which means that if the other party comes into contact with positive and negative electrons, it will inevitably be disturbed.
