Bonding

Question 1

What is a covalent bond?

Answer 1

• held together by electrostatic forces of attraction
• between 2 positive nuclei and a shared pair of electrons
• they are strong, lots of energy is needed to break them

Question 2

What is a simple molecular compound?

Answer 2

• covalent
• each bond has 2 electrons, shared between 2 atoms nuclei
• strong bonds, lots of energy needed to break
• when heated up, intermolecular forces are broken
  -low melting points

Question 3

Why does C60 Fullerene have a low melting point?

Answer 3

• it is a simple molecular structure
• weak intermolecular forces are broken
