Chem Metallic Bonding

Question 1

How does Metallic Bonding form

Answer 1

Electro Static force of attraction between the positively charged metal cations and the sea of de-localized valence electrons

Question 2

name 3 properties of metals

Answer 2

hard, Malleable, Conductors pf elec, high melting/boling points, high density, insoluble in water

Question 3

why metals conduct

Answer 3

sea od DLVE-= free moving and can therefore carry a charge from an electric current.

Question 4

why metals hard

Answer 4

strong force of attraction due to ES force bw cations and sea of dlve-

Question 5

why metals malleable

Answer 5

shifting of layers dosent cause like charges to meet as the sea of dlve- move around to maintain a connection and therefore their is no break in attraction and therefore they dent instead of crack

Question 6

why high melting+ boiling in metals

Answer 6

ES force of attraction= very strong

Question 7

What are Alloys

Answer 7

mix of 2-3 metals which make the substance stronger or harder

Question 8

example of an alloy

Answer 8

Stainless Steel etc.
