Chapter 6 true or false
A molecule with polar bonds must itself be polar
ST
Covalent compounds are network solids
ST
If two of more atoms are covalently bonded together, a molecule of a compound results
ST
To attain a noble gas structure, a nitrogen atom must lose its five valence electrons
NT
A hydrogen bond must involve a hydrogen atom that is covalently bonded to a very electronegative atom
AT
In general the electronegativity values of nonmetallic elements are greater than the electronegavity values of metallic elements
AT
Unshared pairs of electrons affect the shape of molecules
AT
The modern interpretation of resonance is that electron pairs rapidly flip back and forth between the various electron dot structures
NT
In a polar covalent bond the more electronegative atom has a slight positive charge
NT
The compound OF2 contains two double covalent bonds
NT
The tendency of carbon to form four bonds to other atoms can be explained by the four p electrons in its outer shell
