2.4 structure of metals & alloys RISS 12th grade chemistry

what are the 2 types of alloys

• 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

if flourine 64 pm and lithium 121pm combine what type of combination will occur

• additional

• substitutional

• inerstitial

• non-corrosive

valance electrons have a(n) ---------- relationship with attraction

• inverse

• equvilant

• cumilative

• corrosive

type of attraction that holds metal atoms togather

• nuclear

• atomic

• ionic

• coloumbic

in an interstitial alloy atoms------ while they---------- in a substitutional alloy

• fit in between atoms, stick to the owter surface of metals

• are always removed, are always added

• fit in between atoms, replace atoms with similar radii

if a metalic bond is made up of a single element it is known as

• pure metal

• metallic structure

• singular alloy

• non liquid alloy
