Covalent, Ionic, Metallic bonding

Question 0

Ionic Compound Properties

Answer 0

High melting points
often soluble in water
conduct electricity in water
lattice

Question 1

Ionic Bonds

Answer 1

Transfer electrons

Question 2

Why do ionic compounds have high melting points

Answer 2

• opposite charges attract, this forms strong ionic bonds

- lots of energy is needed to separate the ions

Question 3

Electrical Conductivity in Ionic Compounds

Answer 3

• cant conduct when solid
• ions are tightly held in place
• cant carry charges
• can in molten state
• crystal lattice has broken down and the ions can move

Question 4

Metallic Bonding Properties

Answer 4

• High melting point
• high boiling point
  Can conduct electricity and heat
• hard and dense
• malleable
• ductile

Question 5

Metal Atoms

Answer 5

• held together in a sea of delocalised electrons

- each metal gives up electrons into the sea of electrons
