Bonding revision 1

What type of bonding occurs between chlorine and fluorine molecules?

• Ionic
• Metallic
• Weak intermolecular force
• Covalent

Metallic bonding occurs between atoms of

• Sulfur

• Copper

• Fluorine

• Carbon

Which of the following best describes metallic bonding?

• Some metal atoms gain electrons while others lose electrons

• Valence electrons become delocalized and can move freely between cations

• Metal ions form permanent bonds by sharing electrons to obey the octet rule

• Metal atoms use their positive charge to gain additional electrons until every atom has eight valence electrons

Which of the following best describes metallic bonding?

• Some metal atoms gain electrons while others lose electrons

• Valence electrons become delocalized and can move freely between cations

• Metal ions form permanent bonds by sharing electrons to obey the octet rule

• Metal atoms use their positive charge to gain additional electrons until every atom has eight valence electrons

The arrangement of valence electrons in a metallic bond is best described as

• fixed positions in a lattice

• a sea of free-moving electrons

• concentrated electron density around specific atoms

• electron pairs existing in multiple bonds
