Answer 1

To determine which pair of elements would likely form the least polar bonds, we need to look at the difference in electronegativity between the pairs.

The electronegativities are as follows:

• Bromine: 2.8
• Oxygen: 3.5
• Nitrogen: 3.0
• Phosphorus: 2.1

Now, let's calculate the differences for each option:

1. Nitrogen and Oxygen: |3.0 - 3.5| = 0.5
2. Oxygen and Phosphorus: |3.5 - 2.1| = 1.4
3. Bromine and Nitrogen: |2.8 - 3.0| = 0.2
4. Phosphorus and Bromine: |2.1 - 2.8| = 0.7

The pair with the smallest difference in electronegativity is Bromine and Nitrogen (0.2), indicating they would form the least polar bonds with each other.

Thus, the answer is:

bromine and nitrogen.
