70% Sun 12:40 PM User :E CU Denver-CHEM 203 C Which Neutral Atom Is www.saplinglearning.com/biscms/mod/ibis/view.php?id-2... Map Donald Mcquae Peter A. Rodk Ethan Gallogly Nonmetals gain electrons under certain conditions to attain a noble-gas electron configuration How many electrons must be gained by the element O conditions to attain a noble gas electron configuration Number The number of electrons needed to obtain the nearest noble-gas configuration is determined by how far away the element is in relation to the noble gas Which noble-gas electron configuration is attained in this process? neon O radon O xenon O kryptorn O argon helium Bi

Explanation / Answer

ANSWER 2 Electrons

Neon

Explanation Oxygen atomic no is 8 its electronic configuration is 1S2 2S2 2P4

P orbital can accomodate 6 electrons maximum so still oxygen can accept only 2 electrons. If Oxygen gains two electrons then its electronic configuration will be 1S2 2S2 2P6 .

the above configuration corresponds to Neon
