Metallic Bonds and Alloys

Li, Al, Te

Ni, Pb, H

Na, Os, Ga

Ca, Zn, I

positive and negative ions

cations and electrons

two different metals

neutrons and electrons

attached to the most positive ions

shared by all of the atoms

are bonded to the least electronegative element

shiny

sea of electrons that tightly hold the nuclei together

they form triple bonds

low melting point

high luster

hold the layers of ions in rigid positions

maximizes the repulsive force in a metal

allows planes of protons and electrons to slide past one another

are easily broken

the ability to be drawn into a wire

the electrons of metals are mobile

the ability to be hammered into a shape

the ability to be a conductor of electricity

they have mobile electrons

they have mobile atoms

they have crystal structures that can rearrange

they have mobile protons

covalent bonds

metallic bonds

ionic bonds

alloy bonds

their properties are often superior to the component elements

their properties are a blend of the component elements

they never corrode

they are less expensive than their component elements.
