Chapter 1222

"What about the melting point?"

"I can't detect it, but I guess it should be below 1000 degrees, because the weight of the burned gold brick suddenly decreases by a few micrograms. That's exactly the case. We suspect that there are other elements besides palladium, manganese and so on!"

The middle-aged man frowned and paused, saying that they must have evidence of the existence of other metal elements.

"What is the half-life?"

The old professor asked again.

"More than forty minutes!" The middle-aged man was a little uncertain.

"Forty minutes“ The old professor pondered for a moment and continued to ask, "what is the atomic number?"

"Not found yet!"

Shua~

The researchers brought by the old professor suddenly looked at middle-aged men and others. Their eyes seemed to ask, what else?

"Oh ~" the old professor wondered, then something sounded, and then said, "is this metal volatile?"

"It should be that after we heat up, the BRICs lose very little weight in a very short time!" The middle-aged professor said truthfully.

"Go to the CT room!"

……

When the boss came, the professors were still in the CT room, using nuclear magnetic resonance to detect metals.

Metals move when they face a strong magnetic field. The displacement of different metal molecules is different. Like a magnet, it has great attraction to iron and different attraction to other metals.

Then, the specific properties of these metal molecules can be found by relying on strong spectral irradiation.

"Sure enough, there are three kinds of rare metals!" In the testing room, a crowd stared at the data from the computer and began to talk.

"Unfortunately, spectrophotometry and fluorescence spectrophotometry have not detected what these elements are?"

"What about atomic absorption spectrometry?"

Atomic absorption spectrometry, as its name implies, is to radiate light of a certain wavelength, which is not necessarily visible to humans. When the electron transitions from the ground state to the excited state, it will selectively absorb a certain wavelength of radiation. Based on this quantification, the element is determined.

"Alas, this thing seems to have radiation itself?" After a while, the old professor sighed.

In just one day, they did not know how many mid-term tests on this batch of BRICs. Each rare metal detected can startle them. The farther back, the rest is shocked.

I don't know what this detected element is?

"Radiation itself? Radioactive elements? What is the wavelength of radiation? "

"You'd better test it yourself! We have never seen these elements anyway! If today's world had not discovered all the elements that should be found on the earth, I doubt that we would have discovered a new element and won the Nobel prize! "

The middle-aged man shook his head.

He is just an ordinary experimenter. It is out of reach for him to find out what elements won the Nobel Prize.

How could this happen to him.

The only explanation is that they spend too much time detecting these gold bullion elements, and many detection methods are useless.

Perhaps this is the isotope of some element, showing special characteristics.

"Let me see ~"

Two hours later, the old professor did not know what method to take out the samples of elements separated by NMR, and then entered another laboratory.

By this time, the boss had been outside the laboratory.

"Boss, let's hurry! This group of people really told them in advance that you were coming and had to get into some laboratory! " The Secretary beside him seemed impatient.

"Forget it, I'll wait! If you can wait for this strategic metal, everything will pay off! " The vice premier doesn't care.

"Boss, your time is very precious!" The Secretary continued to advise.

"Whose time is not precious? Say they don't necessarily have more important things to do! " The prime minister glanced at the Secretary beside him and said.

Not only the security secretary, but also the dozens of researchers in the research institute must follow the boss after they heard that metal palladium had been found here.

In their words, I can't rest assured!

However, the boss knows that these people must still have doubts, especially Xiao Wu is very skeptical that he can get so many rare metals in one breath.

When they got to the laboratory, they were stopped outside.

Half an hour later, not only the group around the prime minister became worried, but also the people of the Institute became worried.

"I think these inspectors are talking nonsense. They're worried about being exposed. Just hide!"

Xiao Wu finally couldn't wait to stand up and said to his colleagues. His voice was a little loud. Even the vice premier heard it not far away.

"Xiao Wu, don't talk nonsense!"

The old man next to him gave Xiao Wu a hand.

"Then why are they still testing? Don't come out to see people? " Xiao Wu was not satisfied.

"If people encounter any special elements, it is not necessary to re detect them! The prime minister is not worried. What are you worried about? Wait patiently! " The old man glared at Xiao Wu, then shook his head and sighed silently. Today's young people just can't hold their breath.

"It won't take so long!"

"Speak less!"

Sting~

Buzzing~

Just then, the electric gate leading to the laboratory channel slowly started, and more than 20 figures dressed in white fighting monsters appeared in front of the crowd.

As they walked forward, the group took off their hats, masks, gloves and so on.

"Premier, let you wait!"

The head of the old professor quickly took off his gloves, stretched out his hands and strode to the prime minister, and then two pairs of thin old hands held together.

"You worked hard!"

"Not hard!"

"Are the elements you detected this time true?" With a little greeting, the prime minister went straight to the subject.

"It's true! Among these metals, the proportion of gold is the highest, accounting for 70%. In addition, it contains 5% palladium, 4% indium and 6% manganese! This is the test table. After many tests, we can be sure that this data is correct! "

The old professor took out a form from his pocket and handed it to the prime minister.

Compared with the previous document, this table is more detailed, including some detection methods, optical wavelength of elements, number of electrons, half-life and so on.

"You have worked hard to find so many rare metals for the country!"

The prime minister trembled after grabbing the table and checking it again to make sure it was not a deceptive figure.

"Boss, in addition to these rare elements, we also found several other rare elements. Because of the problem of time, we only detected one of them!"

After seeing the prime minister's excited expression, the old professor took a deep breath and decided to take the opportunity to say the new discovery.

"There are other rare metals!"

"Yes, we have found californium!" The old professor said word by word.

"Californium, are you sure?" The boss grabbed the old professor's hand and shook it violently.

"I'm sure!"

Californium is a new synthetic element. No one has found this element in nature for so many years before and after its synthesis.

A gram of gold is only 250 soft sister coins, so a gram of californium is about 70 soft sister coins, and there is still a price without a market. The number of laboratories in the world that can synthesize californium is only a slap in the face today.

"You have made great contributions!"

The boss was excited and incoherent.
