How many valence electrons are need to form single bond?
Single bond is one bond.
It is formed by sharing of 2 electrons, one electron each coming from each atom participating in this single bond formation.
Answer: 2
How many valence electrons that an element need to form a negative ion?
8. How many valence electrons are needed to form a double bond? 9. Why calcium oxide is Cao, not CaO2? (any compound, ionic or molecular compound, the total charge is zero. Ca loses 2 valence electrons to become Ca+2 while o gains two valence electrons to become 02, the total charge is zero. CaO2, is not zero charge, it is -2 net charge.
