Answer 1

To determine which pair of elements would likely form the least polar bonds, we need to consider the difference in electronegativity between the two elements in each pair. The greater the difference in electronegativity, the more polar the bond.

Here are the electronegativities from the table:

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

Now, let's calculate the differences in electronegativity for the provided pairs:

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

From these calculations, we can see that the pair with the smallest electronegativity difference, and thus the least polar bond, is:

Bromine and Nitrogen (difference = 0.2).

So, the answer is bromine and nitrogen.
