Question

Which of the following pairs of atoms are most likely to SHARE electrons (in a covalent bond situation)? *

A.Ca and o
B.N and N
C.Na and ci
D.Kand Br

Answer 1

The pair of atoms most likely to share electrons and form a covalent bond is B. N and N since they are both nonmetals with identical electronegativities, resulting in a nonpolar covalent bond.

Step-by-step explanation:

The question is asking which pairs of atoms are most likely to share electrons and form a covalent bond. In general, nonmetal atoms with similar electronegativities are more likely to share electrons and form covalent bonds. Of the options provided, B. N and N are both nonmetals and have the same electronegativity, which makes them most likely to share electrons equally.

Thus, they would form a nonpolar covalent bond. It is important to note that a covalent bond involves the sharing of electrons to fill the valence shells of the atoms involved, leading to more stable configurations.
