Homework Help: chemistry,

Posted by jane on Saturday, March 3, 2007 at 4:25pm.

,I NEED TO DRAW A LEWIS STRUCTURE for C2n2,cyanogen,and to state the noble gas,i know the answer is neon,but i have far to many electrons and am getting the gas argon,please help


please where do u think i am going wrong

I don't know. You didn't show any work.
C has 4 electrons.
N has 5 electrons.
Total of 9 x 2 = 18 electrons.
Count those around the structure I drew and there are 18. I don't unsderstand the part of the question about noble gas structures. I am familiar with atoms becoming isoelectronic with noble gases but I've never applied that to molecules.

18 is what i got to,thanks for your time Dr bob
