Final answer:
Covalent bonds can form between atoms of equal electronegativity, resulting in a nonpolar covalent bond due to the equal sharing of electrons.
Step-by-step explanation:
The bonds that can form between atoms of equal electronegativity are covalent bonds. This occurs because there is an equal sharing of electrons between the atoms, as they pull on the electrons with the same force due to their equal electronegativity. This leads to what is known as a nonpolar covalent bond.
An ionic bond, on the other hand, forms between atoms of significantly different electronegativity, where one atom donates an electron to another. A hydrogen bond is a type of weak bond that can form between a hydrogen atom and an electronegative atom, but it does not result from a sharing of electrons. Lastly, Van der Waals interactions occur due to transient polarization of molecules, but they are not a result of equal electronegativity.
