Police Detective

"Detachment Cao, you called me." Bai Song knocked on the door and entered.

"Yeah." Besides him, there was another student doing homework in Detachment Cao's room. It seemed that he was Detachment Cao's son, who was sitting at the desk beside him, deep in thought.

When Cao's detachment saw Bai Song, they asked, "What's going on with you and Xiao Sun?"

"It's okay, just a little misunderstanding." Bai Song said with a smile.

"Misunderstanding?" Detachment Cao originally thought that Bai Song would also say a lot of things about Sun Haitao. After hearing what Bai Song said, he thought for three seconds and then said, "Our back office work is still very responsible."

"Yeah." Bai Song nodded.

To say that the work is done responsibly means that there is a problem somewhere else.

Bai Song understood that detachment Cao was giving himself face in disguise. This is just like in the past in the court, if a minister commented on another as "highly talented and extremely talented", it was basically a heart-breaking remark. In ancient times, it was important to have both ability and political integrity. If you praise someone who is talented like this, then To put it simply, it means "morality is not matched".

Sun Haitao has been around for so many years, but he still doesn't understand a single problem. Bai Song is the deputy section leader. Detachment Cao can talk about Bai Song every day, but he should not.

Of course, Cao's detachment was not Bai Song's direct leader, so there were things he disliked about Bai Song but he didn't say anything.

"I just looked at the memory card and video inside you. Are you planning to visit the factory over there?" Team Cao asked about other things.

"Well, it feels a little strange." Bai Song considered his words. Generally, Bai Song would not mention anything to the leader without definite evidence.

"Okay, but what Xiao Sun said is right. Try to avoid this thing in our compound in the future. After all, there are many leading comrades here, and this thing is dangerous after all. If it falls, it will not be good if it hits someone. Got it." After detachment Cao finished speaking, he pointed at the drone.

To put it simply, Cao's detachment's attitude towards Bai Song was that they were too lazy to care about Bai Song because Bai Song was too young.

"Don't worry, Detachment Cao." Bai Song knew that this matter was over at this point. The next step was for Detachment Cao to let him take his things and leave. However, this was a rare visit. This was a good opportunity to ease the relationship. Bai Song took the initiative and said : "Is this your son? He looks like this and is in high school, right?"

"Well, I'm in my second year of high school. Their school is right next to here. Classes start at around two o'clock. I have no place to stay at noon, so I come to study here." Detachment Cao looked at his son with eyes filled with relief.

Bai Song looked at his watch, "It's hard enough. It's already one o'clock and I don't even take a break."

"High school students really have no choice." When it came to children, Team Cao had to chat for a while: "But I heard that you are a top student in Shandong Province who was admitted to the police college. I guess you were more tired than him in high school."

oh? Bai Song thought to himself, Cao's detachment got to know him from the side. It seemed that even if the leader thought he was young and inexperienced, he didn't know anything about him.

"Wherever there is~ it's all returned to the teacher." Bai Song waved his hand and walked to the side of Team Cao's son as he spoke: "What they have learned now... eh? Is this a competition question?"

"Brother, can you tell that this is a competition question?" Cao Yu, the son of Cao's detachment, was a little surprised. Anyway, in his father's opinion, all the questions were the same - no.

"No, it's mainly because this is all university knowledge." Bai Song looked at the paper that Cao Yu was thinking about. Isn't this a university chemistry question? And it was a relatively in-depth study. He immediately said to Team Cao: "Your son is very powerful. If I guess correctly, this is at least a question to participate in the national competition."

"Yes, yes." Detachment Cao was very happy. Showing off to knowledgeable people is the happiest thing.

It's like you got the skin of a Maserati while playing chicken. Showing off to your friends in the chicken game is completely different from showing off to your parents.

"Brother, you are very good. Can you help me with this question?" Cao Yu handed over the paper.

"This question is really difficult for you high school students to think about." Bai Song looked at the question, "But it's very divergent thinking and requires a certain foundation in mathematics and physics."

This question is very broad, "What are your thoughts on the elements after the eighth period of the periodic table of elements?"

"Yes, I heard that all elements can reach up to number 173, but according to the arrangement of the first seven cycles, the eighth cycle can reach element number 168. Will there be a ninth cycle?" Cao Yu For a "genius" with quick eyes, he sometimes expresses doubt that others can solve his own problems.

Bai Song thought for seven or eight seconds and organized his words:

"In fact, there is no completely standard answer to this question, and it is just a question for reflection, because there is currently no clear theory."

"The periodic table of elements begins to be different in the fifth period. Not to mention the lanthanide and actinium series, for example, the rare gases we often talk about, that is, the zero group elements, helium, neon, argon, krypton, xenon, radon, xenon Here, the properties are not like those of noble gases at all.

Xenon is very active. Although its outermost electron shell is full, the ionization energy of the first few electron shells is very low, so the full electrons in the outermost shell are still easy to lose.

Another example is our common metal, gold. The outermost extranuclear electron shell is one electron.

As we all know, metals such as lithium, sodium, and potassium, which have only one electron in the outer layer, are very active. However, the properties of gold atoms are not only related to the outermost electron, but also to the penultimate electron layer, which involves relativistic effects.

For elements in the eighth cycle, the problem in this regard is even more serious.

According to the current structure, the eighth cycle ends with element 168, but in the Bohr model, it ends with element 137.

In addition, there are some other models, such as

These models are very interesting. Some theories believe that due to the excessive overlap of electron orbits, the problem of layer filling of electrons is very large. Some people even mentioned that the last element in the eighth cycle is element 172, while elements 165-168 Will run to the ninth cycle

These are basically hypotheses. You can search online for Seaborg model, Frick model, Nefedov model, and Pecapiko model."

Bai Song talked more and more, and by the way explained the principles of relativity and quantum mechanics involved. It was past 1:30 by accident.

"Well, that's about it. I have a book over there. I can bring it over to you later." Bai Song has finished reading the inorganic chemistry book, and he also made a lot of annotations in the book, which is very interesting to Cao Yu. help.

After Bai Song finished speaking, Cao Yu looked excited, "Okay, thank you, brother."

Obviously, Cao Yu understood most of it and was still thinking about it, while Cao's detachment was completely confused.

This is where? Is it your own office? For the first time, detachment Cao began to doubt himself.

There will be an extra update tonight, thanks to the leader.
