Chapter 1222 (1/2)
”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.
