3 Describe how metals polymers and ceramics bond at the atom
Solution
Solution:-
(1) Answer:- Metal Bonding:- Metal bond are force between valence electrons of the atoms. It is sharing of electrons between many positive ions. Electrons act as glue in this bonding.
Metal bonding effect properties of metal like strength,ductility,thermal and electrical resistivity etc.
(2) Answer:- Polymers Bonding:- Polymer is made from many monomers.A single polymer molecule can consist of hundred to a million monomers and have a linear branched structure.Covalent bonds hold the atoms in the polymer molecules together.
Polymer bond effect on polymer dencities , polymer absorb light , polymer is not conductor of electricity.
Uses:- in medical , In agriculture, sports
(3)Answer:- Ceramic bond:- The atoms in ceramic material are held by a chemical bonding .Bonding between atoms and atoms are packed together.This is atomic scale structure. Many chemicals are made of two or more elements. This is called compound.
Properties of ceramic:-Hard, brittle, thermal insulators,nonmagnetic etc.
Uses:- Gas burner nozzles , ceramic disk brake, missile nose cones , bearing etc.
