Based on the information in the table, which pair of elements would likely form the least polar bonds with each other?
A. oxygen and phosphorus
B. phosphorus and bromine
C. nitrogen and oxygen
D. bromine and nitrogen
The table information is missing, so it is not possible to determine which pair of elements would form the least polar bonds with each other.
