Covalent Bonds Test Questions with Correct Answers

Covalent Bonds Test Questions with Correct Answers Covalent bond - Answer-When to atoms share electrons molecular orbital - Answer-The space that these shared electrons move within Which statement is true about a molecule of H2? - Answer-Each atom has an electron configuration like that of Helium and the electrons from both atoms travel within the molecular orbital. A single covalent bond involves the sharing of - Answer-two electrons. If two covalently bonded atoms move closer than a distance of the bond length, the potential energy of the atoms - Answer-increases. The electrons involved in the formation of a covalent bond are - Answer-valence electrons. Bond energy is the energy - Answer-required to break one mole of similar bonds in a compound. Bond length between two bonded atoms is - Answer-the separation at which their potential energy is minimum. Which compound most likely has the greatest bond energy? - Answer-HF;H-F bond length= 92pm Nonpolar covalent bonds are not common because - Answer-one atom usually attracts electrons more strongly than the other. To draw a Lewis structure, it is not necessary to know - Answer-a length of the bonds. The Lewis structure that represents an atom in Group 16 of the periodic table has - Answer-two pairs of valence electrons and two single valence electrons.
