When atoms of two elements with a medium difference in electronegativity bond together, the bonding is probably
A) ionic.
B) covalent.
C) polar covalent.
D) metallic.

Question

Quizplus · Accepted Answer

When atoms of two elements have a medium difference in electronegativity, they tend to share electrons unequally, leading to polar covalent bonding. This is because the element with the higher electronegativity will attract the shared electrons more strongly than the other, creating a dipole moment.
