Which of the following species has a bond order of 1?

Which of the following species has a bond order of 1?

Correct Answer: F2

Step 1: Understand what bond order means. Bond order is a way to measure the strength and stability of a bond between two atoms.
Step 2: Know that bond order can be calculated using the formula: (Number of bonding electrons - Number of antibonding electrons) / 2.
Step 3: Identify the species in question, which is F2 (Fluorine molecule).
Step 4: Determine the number of bonding and antibonding electrons in F2. F2 has 8 bonding electrons and 6 antibonding electrons.
Step 5: Plug the numbers into the bond order formula: (8 bonding electrons - 6 antibonding electrons) / 2.
Step 6: Calculate the bond order: (8 - 6) / 2 = 2 / 2 = 1.
Step 7: Conclude that F2 has a bond order of 1.
