Option: 1

2, 8, 8, 18
 


Option: 2

2, 8, 8
 


Option: 3

2, 8, 8, 1

 


Option: 4

2, 8, 8, 7


Answers (1)

Elements having electronic configurations of 2, 8, 8 and 2, 8, 8, 18 are noble gas configurations. Electronic configuration 2, 8, 8, 7 belongs to the halogen group which is more likely to gain one electron to attain noble gas configuration.
Whereas electronic configuration 2, 8, 8, 1 has only 1 electron in its valence shell. It shall readily lose 1 electron to attain noble gas configuration.

Hence option 3 is correct.
