2.1 Types of Chemical Bonds

Electronegativity values for the representative elements increase/decrease going from left to right across a period

Increase

Electronegativity values for the representative elements increase/decrease going down a group

Decrease

Trends in electronegativity values can be understood qualitatively through the:

Electronic structure of the atoms, the shell model, and Coulomb’s law

Valence electrons shared between atoms of similar electronegativity constitute a:

Nonpolar covalent bond

Bonds between carbon and hydrogen are effectively polar/nonpolar

Nonpolar

Carbon is slightly more/less electronegative than hydrogen

More

Valence electrons shared between atoms of unequal electronegativity constitute a:

Polar covalent bond

The atom with a higher electronegativity will develop a ______ relative to the other atom in the bond

Partial negative charge

In single bonds, greater differences in electronegativity lead to:

Greater bond dipoles

Do all polar bonds have ionic character?

Yes

The difference between ionic and covalent bondng is distinct / a continuum

A continuum

Is difference in electronegativity the only factor in determining if a bond should be designated as ionic or covalent?

No

Bonds between a metal and nonmetal are:

Ionic

Bonds between two nonmetals are:

Covalent

What is the best way to characterize the type of bonding?

Examination of the properties of a compound

In a metallic solid, the valence electrons from the metal atoms are considered to be:

Delocalized and not associated with any individual atom
