Question

The number of valence electrons in the O 2 − ion is ______. A) 4 B) 6 C) 8 D) 10

Vikas TU · Answer

Dear student

Oxygen has atomic no. 8. Its electronic configuration becomes 2,8,6 i.e it has 6 valence electrons. In O2−
there are two more electrons. Hence number of valence electrons in the O2− is 8.
