Which of the following statements is not true?A covalent bond involves the sharing of electron pairs between atomsA covalent bond forms when one atom gives up one or more electrons to another atomAtoms react to gain a full outer shell of electronsAtoms react to gain the same electron configuration as the nearest noble gas

Which of the following substances is held together by covalent bonding?

use the idea that intermolecular forcesare weak compared with covalent bonds to explain the bulkproperties of molecular substances.

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.
