Still seek Hai?
Pulled a Mu match to stop an experiment, let everyone had lunch.He also left laboratory by himself and let the liquid air of the Du tile bottle inside continue to evaporate.
About lead a half hour, pull a Mu match just return to laboratory.The liquid air of the Du tile bottle inside left not much, but he isn't regrettable at all.He thinks:Hai spirit than oxygen and nitrogen annoy to evaporate slowly and delay more some time, can let oxygen and nitrogen spirit first run away, Hai the spirit will remain a bottle at the Du tile in.
Wait until liquid air leave the time of about 10 cubic centre-metre rices and pull a Mu match don't let they white white the ground ran away.He evaporates end this liquid air of the air cautiously collect.He thinks that in part of air of end, will definitely have Hai spirit.
For removing oxygen and nitrogen spirit of this surplus in part of air, pull a Mu match to let the air pass to have red hot copper scraps and red hot porcelain tube of magnesium scraps, finally get a few atmosphere bubbles.
The bubble is sealed in the middle of turning on electricity a tube, high pressure of electricity, give out light.Pull a Mu match to start studying its spectrum.
He saw orange and the table line of green, this is the table line of argon, have no wrong.But what to disappoint me BE, anticipate of that yellow of the words line of Hai didn't appear.
There is no Hai!
See to pull a Mu match to estimate wrong.One may basically have no Hai spirit in the air;Being another may be a Hai spirit to evaporate very quickly and even to annoy to evaporate than the oxygen and nitrogen still quickly, it early escaped.
But pull a Mu match not to regret, he cautiously observes spectrum and discovers the new table line of two brightnesses, 1 is yellow, and 1 is green.These two table line heels have already known that material table none of line weighs to match.Turn on electricity a tube obviously in in addition to argon gas, there is also new air.
Pull a Mu match while studying hundred million air in the uranium mineralses, once was called the Ke to the Hai.This time, he seek the time of Hai new air chemical element discover, was called "Ke".
Pull a Mu match to think so up in the air seek Hai, the Hai didn't seek, but discovered Ke.This is really the surprised detection.
This is the business on May 24, 1898.
Was up in the air to find out Hai
The this time didn't find out Hai, pulling the Mu match didn't lose confidence.He has already stored 15 rise from withdraw in the air of ammonia spirit, he believes the Hai spirit mixs in these argon gases.The result tested by top can anticipate, the Hai is a very easy evaporation.He and his young assistant especially Lai any Si designed a new experiment project.
Led for several days, in 6 beginning of the months, the man Pu loosen and delivered liquid air, the this time has quite a few to rise.The new experiment started, they a carry is the glass tube of spheroid to immerse in the Du tile bottle of having the liquid air, then that 15 rise from withdraw in the air of argon gas, slowly send to a glass tube inside.Under the temperature of liquid air, the argon gas Ning became liquid and accumulated in the ball to about have 13~14 cubic centre-metre rices.
Finally, they closed glass to take care of up of piston.By this time, the glass tube still immerses in the liquid air.Led for several minutes, they glass tube in of don't liquefy of the air took out out and packed in to turn on electricity a tube.
After switching on electricity, this air at turn on electricity to send out a beauty in the tube of red light.
Use up to compose an instrument check, pull a Mu match and especially Lai any Si discovered the table line in a few bright orange red.Check a rightness for a while, this is again new air.
They rise name for this new air chemical element to be called neon(Greek"new" meaning)-the our country translate to make "Nai".
Cautiously check again for a while, they found out the table line of that yellow line-Hai in the spectrum, the position wasn't bad at all.But this yellow line is very obscure, explain that the Hai spirit is few.
The Hai was again found out.This once was a very mysterious sun chemical element and originally had in the air of our surroundings.
After several years, pull the Mu match is in detection process that speak of Hai in the public lecture, he says:"Look for Hai, make me thought of that the old professor seeks the joke of glasses.He tries very hard to of seek in the underground, seek on the table, the newspaper underneath seeks and seeks around, originally the glasses put on own sum Cape.The Hai is also sought for a long time, but it in the air."
The new household in the air
In the experiment of top, 15 rise from withdraw in the air of the argon gas be frozen by the liquid air liquid.Pull a Mu match and especially Lai any Si drew out liquid first the top didn't liquefy of air, discovered Nai, there is also Hai.Immediately after, they let the liquid continuously evaporate, and a per ground draw out the air of evaporation and check their spectra.
Beginning, the air of the collections big part is an argon, later on, is the Ke that discovered lately.But pack end a little air into turn on electricity a tube, electricity of but send out beauty of blue light, another kind new of the air chemical element was disheveled hair now.This is the business on July 12, 1898.
New air chemical element of this kind of hair blue light answers to the name of xenon(Greek"unfamiliar" meaning)-our country translate to make "Xian".
So, pull a Mu match after getting liquid air, in less than one and half months, up in the air discovered three kinds of new air chemical element-fluorines, Nai and Xian again.
Make us back and forth attend to this history now:In the Rui benefit and pull a Mu match up in the air discover argon before, the scientists all thinks that the air constitutes to°from the oxygen and nitrogen.Pull a Mu match immediately after and especially Lai any Si proved that the argon that discover in times before isn't a pure air either again, its inside still mixs Hai, Nai, the Ke and the Xian.
For studying the property of these air, pull a Mu match and especially Lai any Si distiled a great deal of liquid air, they got pure argon gas, pure Ke spirit and pure Xian spirit.But Nai spirit and Hai annoy always together, can not separate them, because under the temperature of liquid air,beats by dre studio, they can't become liquid.
Need to compare liquid air much lower temperature, just probably make Nai spirit and Hai spirit become liquid.This hydrogen that needs to use liquid.The boiling point of liquid air is below zero 192 Celsius degreeses, while the boiling point of liquid hydrogen is below zero 253 Celsius degreeses.
But there is the hydrogen of liquid in[at] where?Before mention of the Du tile, can once make in 1898 liquid hydrogen.But he even the liquid airs aren't willing to give other people, say nothing of liquid hydrogen.How to do?
Especially Lai any Si decision packs a set machine to make by himself/herself liquid hydrogen.After some kind of effort, it was liquid hydrogen to really get!Head a batch of products-100 cubic centre-metre rices of liquid hydrogen, immediately use to separate Nai spirit and Hai spirit.
The hybrid air of the Hai spirit and Nai spirit sent in to immerse at liquid hydrogen in of glass small ball, the Nai spirit not only becomes liquid, but also immediately condenses solid, the Hai spirit still keep being air.Hence, Hai spirit and Nai of the most difficult separation annoyed to also separate.
Pull a Mu match and especially Lai any Si proof:At 1 get off the ground and annoy in about have the argon gas of 10 cubic centre-metre rices, 18 sign square the Nai spirit of the millimeter, 5 sign square the Hai spirit of the millimeter, 1 sign square the Ke spirit of the millimeter, the Xian spirit is the minimal, only 0.1 sign square millimeter.
For in detail studying the property of these air, they successively used 3 years.
They measuresed each gaseous density, result is press the order of sequence of Hai, Nai and argon, Ke and Xian, a bigger than one.
They did many chemistry experiments, result proof, this group air, not only argon gas and Hai spirit, be behind discover of Nai spirit, hydrogen and Xian spirit, also Be not willing to take place with any material chemical reaction.They aren't very cheery, so people are called"sloth air" to them.On the Jie row man periodic table in door, Hai, Nai, argon, Ke and Xian formation alone of one clan-zero
