substitutional
additional
interstitial
intracellular
if boron 84pm and carbon 69pm are combined what type of alloy is created
multicellular
substitutional
partial
interstitial
metals are made of -------- that are embedded in delocalized sea of valance electrons
(a)
the biggest difference between substitutional and interstitial alloys are
substitutional alloys have a minor size difference while interstitial alloys have a large size difference
substitutional alloys have a major size difference while intercellular alloys have a minor size difference
substitutional are liquds found to be highly conductive while interstitial are liquids that are highly flamable
none of the above
