Which of the following values best classifies a bond between 2 atoms as being covalent?A.An electronegativity difference of greater than 1.7 between the atomsB.An electronegativity difference of less than 1.7 between the atomsC.An electronegativity difference of greater than 2.7 between the atomsD.An electronegativity difference of less than 2.7 between the atoms

A covalent bond involves which of the following?donation of protons from one atom to anotherelectrostatic attraction between opposite chargestransfer of electrons between two atomssharing of protons between two atomssharing of electrons between two atoms

In chemical bond formation, covalent bonds are generally formed by electron:A.sharing between two atoms with a small or moderate electronegativity difference.B.sharing between two atoms with a large electronegativity difference.C.transfers between two atoms with a small or moderate electronegativity difference.D.transfers between two atoms with a large electronegativity difference

Which of the following best describes a polar covalent bond?Multiple choice question.Brief fluctuations in electron density create oppositely charged regions in two atoms that then attract one anotherElectrons are shared unequally between two atoms.Electrons are shared equally between two atoms.Electrons are transferred from one atom to another to generate oppositely charged ions that are attracted to one another.

2. A covalent chemical bond is one in which:a. electrons are removed from one atom and transferred to another atomso that the two atoms become oppositely charged.b. protons and neutrons are shared by two atoms so as to satisfy therequirements of both atoms.c. outer-shell electrons of two atoms are shared so as to satisfactorily fillthe outer electron shells of both atoms.d. outer-shell electrons of one atom are transferred to the inner electronshells of another atom.e. the inner-shell electrons of one atom are transferred to the outer shellof another atom.

What does the presence of a polar covalent bond show about the electronegativities of its two atoms?A.The electronegativities of the two atoms are the same.B.The difference in electronegativities is greater than 1.7.C.The effects of electronegativity differences are canceled out.D.The electronegativities of the two atoms are not equal.
