Bond order for O2+2
Correct answer: A. Two
- A. Two
- B. One
- C. Zero
- D. None of the above
Explanation
The bond order for O2+2 is two, indicating a double bond.O2+2 is a diatomic molecule with two oxygen atoms. To determine the bond order, we need to calculate the difference between the number of bonding and antibonding electrons and divide by 2.For O2+2:Number of bonding electrons = 10 (5 from each oxygen atom)Number of antibonding electrons = 6 (3 from each oxygen atom)Bond order = (Number of bonding electrons - Number of antibonding electrons) / 2= (10 - 6) / 2= 4 / 2= 2

About Electronic Configuration
Electronic configuration describes how electrons occupy shells, subshells and orbitals around an atom. Questions use the Aufbau principle, Pauli exclusion principle and Hund's rule to write configurations, identify valence electrons, form ions and explain periodic trends, including common exceptions such as chromium and copper.
