Nonmetals gain electrons under certain conditions to attain a noble gas electron configuration. 

How many electrons must be gained by the element sulfur (S) to attain noble gas electron configuration? 

number of electrons: _______ 


Which noble gas electron configuration is attained in this process? 

xenon 

radon 

neon 

krypton 

helium 

argon

Solutions

Expert Solution

Atomic no of Sulfur(S) is 16.

Therefore the electronic configuration will be 1s22s22p63s23p4.

The outermost shell contains 6 electrons, So it needs 2 more electrons to attain noble gas electronic configuration(8 electrons in outermost shell).

After gaining 2 more electrons the electronic configuration will be

S2- = 1s22s22p63s23p6

Which is the electronic configuration of Argon(atomic no - 18)
