Metallic Bonding

Question 1

Define Metallic bond

Answer 1

efa between a lattice of positive ions and sea of delocalised electrons

Question 2

2 factors affecting the strength of metallic bonds

Answer 2

1. Number of delocalised electrons
   - more-> stronger attraction => stronger bond length
2. Charge density
   =charge/size
   -higher->stronger attraction => stronger bond length

Question 3

What are the three properties of metals?

Answer 3

1. High melting and boiling point
   - a large amt of energy is req’ed to overcome….. in a giant metallic lattice structure
2. Good conductors of electricity in solid and molten star
   - mobile electrons -> charge carriers
3. Ductile and malleable
