chemistry at 2011 (part 2)
In part 1, i said about a great chemist who left us in the year of 2011.
Now i shall say a story. In Indian epic Mahabharat there is a story about 101 children of a king. Now in my story there is 118 characters.They live in a large palace.You know the engineer who constructed the palace. He is Henry Moseley.He buit 118 mysterious rooms. I forget to say about the old palace.It was Mendeleev who buit that.Now coming back to Moseley's palace.As i said, it is having 118 mysterious rooms. The chemists all over the world is trying to open all the rooms. They opened all the rooms till room number 110. Yes, name of the palace is periodic table ,the holy Bible of chemists.Five new elements were discovered in the year 2011. They are Darmstadtium(Ds),Roentgenium(Rg),Copernicium(Cn),Flerovium(Fl) and Livermorium(Lv).They are having the atomic numbers 110,111,112,114 and 116 respectively.They are superheavy elements.Copernicium and Roentgenium got its name from the name of two great physicists. One of them introduced Heliocentric theory and the other discoverd X-ray..Chemists are trying hard to discover elements having atomic number 113, 115 etc.. Friends lets welcome the new elements who joined us in 2011. There are still more members to come in 2012

Roentgenium was discovered by S.HOFMANN,V.NINOV,F.P.HESSBERGER,P.ARMBRUSTER,H.FOLGER,G.MUNZENBERG at 1994 in GSI in Darmstadt,GERMANY. ORIGIN OF NAME:The proposed name Roentgenium has yet ot be accepted formally but lies within the long established tradition of naming element to honour famous scientist WILHELM CONRAD ROENTGEN discovered X-rays in 1895. Three atoms of an isotop272Uuu were produced in reactions between 209Bi target & 64Ni projectiles to achieve this ,the nickel atom were accelerated to high energies by the heavy ion accelerator UNILAC at GSI & directed onto a lead target
ReplyDeleteIn honour of scientific & astronomer NICOLAS COPERNICUS the discovering team around professor SIGURD HOFMANN suggested the name ,"copernicium" with the element symbol "Cp" for the new element 112,discovered that the earth orbits ,the sun ,thus paving the way for our modern view of the world Thirteen years ago, element 112 was discovered by an international team of scientists at the GSI accelerator facility
ReplyDeleteDarmstadtium discovered by PETER ARMBRUSTER & GOTTFRIED MUNZENBER. ORIGIN OF NAME:The name Darmstadtium lies within the tend established tradition of naming of an element after the place of discovery , Darmstadtium in Germany
ReplyDeleteThis is what i wanted and this is what i expected.. Afsi great job..u given us more specific and detailed information..(this will be useful to thousands of people reading this,, as per the stats average 100 persons is visiting this blog daily,it will surely help them)
ReplyDeleteAfsi... U said symbol of copernicium is Cp.. Its Cn.
ReplyDeleteThank you AKSHAY
