CHEM 333 chemistry: bonding and lewis
structure Questions and Answers 2026 Latest
Update
covalent bond Ans: sharing electron pairs
nonpolar covalent Ans: identical
polar Ans: unequal attraction for the shared electrons
high electronegativity Ans: strong attraction for electrons (halogens-
fluorine)
polar covalent Ans: bonds that have 5%-50% ionic character
ionic character Ans: The greater the electronegativity difference between
two bonded atoms, the greater the percentage of ___ in the bond
valence electrons Ans: electrons in the formation of a chemical bond
ionic bond Ans: bond that results from the electrostatic attraction between
positive and negative ions
how does a covalent bond hold two atoms together Ans: A pair of electrons
is attracted to both nuclei of the two atoms bonded together
electronegativity Ans: determines whether or not the bond will be polar
electronegativity greater than 1.7 Ans: ionic
exceptions from the octet rule Ans: hydrogen, boron,, beryllium,
phosphorus, sulfur, xenon
resonance structures Ans: show delocalized electrons
NH3 Ans: ammonia
