A covalent bond may also be termed a molecular bond. All of the atoms' electrons are shared between the atoms please help A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. The best guide to the covalent or ionic character of a bond is to consider the types of atoms involved and their relative positions in the periodic table. b. Ionic bonds are chemical bonds formed when atoms transfer electrons to other atoms. b. the transfer of electrons from one atom to another. Continue to order Get a quote. Problem: An ionic bond is best described as: a. the sharing of electrons. If the atoms that form a covalent bond are identical, as in H 2, Cl 2, and other diatomic molecules, then the electrons in the bond must be shared equally.We refer to this as a pure covalent bond.Electrons shared in pure covalent bonds have an equal probability of being near each nucleus. Which statement best describes 'Electronegativity'? If the atoms that form a covalent bond are identical, as in H 2, Cl 2, and other diatomic molecules, then the electrons in the bond must be shared equally.We refer to this as a pure covalent bond.Electrons shared in pure covalent bonds have an equal probability of being near each nucleus.
