|
a mixture of elements that has metallic properties; most commonly forms when the elements are either similar in size (substitutional) or the atoms of one elements are much smaller than the atoms of the other (interstitial)
|
alloy
|
|
|
an ion that has a negative charge; forms when valence electrons are added to the outer energy level, giving the ion a stable electron configuration
|
anion
|
|
|
an ion that has a positive charge; forms when valence electrons are removed, giving the ion a stable electron configuration
|
cation
|
|
|
the force that holds two atoms together; may form by the attraction of a positive ion for a negative ion or by the attraction of a positive nucleus for negative electrons
|
chemical bond
|
|
|
the electrons involved in metallic bonding that are free to move easily from one atom to the next throughout the metal and are not attached to a particular atom
|
delocalized electrons
|
|
|
an ionic compound whose aqueous solution conducts an electric current
|
electrolyte
|
|
|
proposes that all metal atoms in a metallic solid contribute their valence electrons to form a sea of electrons, and can explain properties of metallic solids such as malleability, conduction, and ductility
|
electron sea model
|
|
|
the simplest ratio of ions represented in an ionic compound
|
formula unit
|
|
|
the electrostatic force that holds oppositely charged particles together in an ionic compound
|
ionic bond
|
|
|
the energy required to separate one mole of the ions of an ionic compound, which is directly related to the size of the ions bonded and is also affected by the charge of the ions
|
lattice energy
|
|
|
the attraction of a metallic cation for delocalized electrons
|
metallic bond
|
|
|
an ion formed from only one atom
|
monatomic ion
|
|
|
the positive or negative charge of a monatomic ion
|
oxidation number
|
|
|
a polyatomic ion composed of an element, usually a nonmetal, bonded to one or more oxygen atoms
|
oxyanion
|
|
|
an ion made up of two or more atoms bonded together that acts as a single unit with a net charge
|
polyatomic ion
