Chapter 6 Ionic Compounds and Metals

chemical bond

the force that holds two atoms together

cation

A positively charged ion

anion

A negatively charged ion

ionic bond

the electrostatic force that holds oppositely charged particles together in an ionic compound

crystal lattice

three dimensional geometric arrangement of particles in an ionic compound

formula unit

represents the simplest ratio involved in an ionic compound

metallic bond

the attraction of a metallic cation for delocalized electrons

When elements combine to form an ionic compound

which group
of elements is the electron configuration of the ionic compound
going to be identical to?

Which type of chemical bond generally forms between
a metal and a nonmetal?

An ionic bond generally forms between a metal and a nonmetal

Which type of chemical bond is found in solid substances that
are excellent conductors of heat and electricity?

metallic bond

When an atom becomes a positive ion

does it have
more protons or more electrons?

When an atom becomes a negative ion

does it have
more protons or more electrons?

Which types of solid substances contain atoms that contribute their valence electrons to form a "sea" of electrons?

metals

Why do atoms gain or lose valence electrons?

Atoms gain or lose
electrons to form
the octet-the stable
arrangement of
eight valence
electrons in the
outer energy level.

Identify
the phase in which an an ionic compound can conduct
electricity

The
overall charge of
a
formula unit
for an
ionic compound
is zero
.

Which types of substances will conduct
electricity as either a solid of a liquid?

Metals
will conduct electricity as either a
solid or a liquid.
