How many valence electrons are in o-
WebCorrect option is C) Oxygen has atomic no. 8. Its electronic configuration becomes 2,8,6 i.e it has 6 valence electrons. In O 2−, there are two more electrons. Hence number of valence electrons in the O 2− is 8. Was this answer helpful? WebTotal number of electrons of the valance shells of F 2 O. Fluorine is a group VIIA element. Therefore, fluorine has seven electrons in its last shell. ... Then, there are two (8-6) many electron pairs to mark on oxygen atom. Charges on atoms. There are no charges on atoms. Therefore, this structure should be the lewis structure of F 2 O.
