5.4 what are the properties of metals and alloys

Question 1

what is the metallic bond

Answer 1

the metallic bond is th mutual electrostatic attraction between positively. harfedmera, ions and the ‘sea of delocalised electrons’

Question 2

alloy

Answer 2

a mixture of a metal with one or more elements

Question 3

structural properties of pure metals

Answer 3

pure metals have a regular structure and if enough force is alllied, the layers of atoms can slide over one another easily

Question 4

structural properties of alloys

Answer 4

atoms of different elements disrupt the regular arrangement thus atoms of different sizes cannot slide over each other easily

Question 5

why are pure metals known to be malleable and ductile

Answer 5

the atoms are arranged in orderly layers, which can slide over one another easily through the ‘sea’ of delocalised electrons when a force is applied

Question 6

melting points and boiling points of metals

Answer 6

metals usually have a high melting and boiling point because the metals are held together in a lattice by strong metallic bonds

Question 7

melting and boiling points of alloys
