IB SL CHEM - Metallic Bonding

What is the main factor that determines the strength of metallic bonding?

• Number of protons provided by the atoms

• Size of the metal ions

• Number of neutrons provided by the atoms

• Number of electrons provided by the atoms

What is the charge on the ions formed by Group 2 metals when they lose electrons?

• 3+

• 4+

• 1+

• 2+

What gives metals their unique characteristics?

• Presence of noble gases

• Formation of ionic bonds

• Delocalised orbital electrons

• Formation of covalent bonds

Which factor contributes to stronger metallic bonding?
