Chapter 9 - Models of Chemical Bonding

negative particles

Bonding, in general, reduces the potential energy difference between positive and ________, whether they be oppositely charged ions or nuclei and electrons.

Metallic bonding

________ occurs when a large number of metal atoms pool their valence electrons into a delocalized electron "sea "that keeps all the atoms in the sample together.

Metal

________ with nonmetal: electron transport and ionic bonding, as seen in the picture below.

massive number of atoms

The ________ in a metal sample pool their valence electrons in a "sea "of electrons that "flows "between and around each metal- ion core (nucleus + inner electrons), attracting and keeping them together.

Covalent bonding

________ is more frequent between nonmetal atoms and produces distinct molecules.

valence electrons

Each atom in the bond's nucleus pulls the ________ of the other, drawing the atoms together.

valence electrons

Metals have very high boiling points because vaporization involves the complete separation of individual cations with their ________ from all the others.
