Metallic bonding：练习题

• a.The sharing of electrons between non-metal atoms.
• b.The attraction between molecules due to weak intermolecular forces.
• c.The attraction between oppositely charged ions.
• d.The electrostatic attraction between positive ions and a 'sea' of delocalised electrons.

• a.A shared pair of electrons between two non-metal atoms.
• b.The attraction between oppositely charged ions in a regular repeating arrangement.
• c.Weak intermolecular forces between neutral metal atoms.
• d.The electrostatic attraction between positive ions and a sea of delocalised electrons.

• a.The metallic bonds are broken and new ones are formed.
• b.The sea of electrons becomes concentrated at the ends of the wire.
• c.The layers of ions slide over each other while delocalised electrons maintain the bond.
• d.The metal ions lose their charge and become neutral atoms.

• a.

  The electrostatic attraction between positive ions and a sea of delocalised electrons.

• b.

  The sharing of electron pairs between two metal atoms to achieve a stable configuration.

• c.

  The attraction between protons in the nucleus and the outer shell electrons of the same atom.

• d.

  The electrostatic attraction between alternating positive and negative ions.

• a.The strong covalent bonds between metal atoms allow for high conductivity, and the irregular arrangement of atoms allows for malleability.
• b.Delocalised electrons can move throughout the structure to carry charge, and layers of positive ions can slide over each other without breaking the metallic bond.
• c.The presence of different-sized metal atoms allows electrons to flow easily, and the layers of atoms are locked in place by strong electrostatic forces.
• d.Positive ions move freely through the giant lattice to carry current, and the electrons act as a lubricant between the layers of atoms.
