Metallic Bonding Flashcards
Pure metals are crystalline solids, but unlike ionic compounds, every point in the crystal lattice is occupied by an..
identical atom
The electrons in the outer energy levels of a metal are?
mobile and capable of drifting from one metal atom to another
Metal is viewed as an array of positive ions surrounded by a sea of mobile valence electrons called?
Delocalized electrons
the attraction of the stationary metal cations to the surrounding mobile electrons
Metallic Bond
In a metal, the stationary metal cations are surrounded by a sea of mobile valence electrons that are not associated with?
any one cation
Metals conduct ___________ and _____ very well because of their free-flowing electrons.
electricity and heat
When light is shone onto the surface of a metal, its electrons absorb small amounts of energy and become excited into one of its many empty orbitals. The electrons immediately fall back down to lower energy levels and emit light. This process is responsible for the _____ _______ of metals.
high luster
Metals can be hammered into shapes, rolled into thin sheets, or pulled into thin wires. Meaning that they are?
very malleable and ductile
The metallic bond is responsible for the?
properties of metals
