electronic configuration the Cu is 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d9 ( 4s2, 3d9), whereas because that Cu2+ is , 3d9. I uncovered some regular tables and also electronic configuration notes, over there is 4s1, 3d10 for Cu. Isn't electron need to be fill very first 4s (2 e) and also then 3d9? and for the ionize state of Cu (Cu2+) electron shouldn't be escape from the 4s state? likewise I'm trying to find the reason of electronic configuration 4s1, 3d10.

Dear Abdur Raheem, the digital configuration that Cu is 3d10 4s1 because, fully filled subshell exhibit extra stability. The digital configuration that Cu2+ is 3d9.
d10 is an alleged to be more stable 보다 d9. For this reason Cu(I) v d10 configuration have to be much more stable yet on the contrary, Cu(II) v d9 is more stable. You re welcome explain.
I desire to calculation the formation power of benzene, naphthalene, coronene. Is that measured in ax of every atom (atom-1) ?
ACS used Nano materials (https://pubs.acs.org/journal/aanmf6) and ACS used Energy materials (https://pubs.acs.org/journal/aaemcq) both research journals introduced at the same time. ACS used Energy Materials has got influence Factor (I.F) = 4.473 when ACS used Nano products still no exist. Why?
Can someone please assist me concerning how to draw the spin thickness plots as stated in the record attached herewith. Exactly how the turn up and spin down densities have the right to be separated?
I have actually tried come optimize Fe(III) high spin complicated in ORCA program, but the calculation terminating every time v error. I can not able to uncover the solution from searches. Can anybody indicate me to uncover the systems for successful calculation.
I have actually a spectrum the Co(2p) (see fastened picture) and also would choose to recognize the precise state that oxidation of Co. They space two main peaks at 785,6 eV because that Co2P(3/2) and 800,9 eV because that Co2P(1/2), and also two optimal satellite in ~ 791,6 ev and also 808,5 ev. 
Congratulations, Your current publication has actually been provisionally selected for research study Awards and also recommended by our scientific committee. So kindly nominate through your recent research profile/resume v an online entry system. After a few steps of profile verification and registration procedures you will obtain your research study Award.
Selected compensation Category: ideal Research AwardNote: Submit her updated profile under the selected award category.
There was additionally a nomination link, which I eliminated from the text over and that ns did not try to open, and also the summary of a record that was welcomed a couple of days ago and made accessible online about 10 hours prior to that mail was being sent. According to the website (https://sciencefather.com/awards/), one demands to salary a it is registered fee in order to use for one award. Is this a new scam? thanks for her help.
Transmission functions and also hence electron six of linear- (ethylene come 1-hexene) and cis-cyclo-alkenes (5- come 8-membered rings) space measured by a 127° electron-transmission spectrometer. Compare is made in between reported shifts in electron affinities and existing worths of ionization potentials.
