Malleable is the ability
of a metal to be
hammered into a thin
sheet.
Ductile is the ability of
a metal to be drawn
into thin wires.
Conductor means an
element has the ability to
carry electric current or
heat (thermal energy).
Reactivity means an
element has the ability
to combine with
other elements.
Brittle means an
element breaks easily.
Shiny is the ability of
an element to reflect
light.
Dull is not being shiny
(does not reflect light..
Semiconductors carry
some electric current
when certain conditions
are present.
They can not carry
heat or electric
current through them.
