Exploring Chemical Bonds Quiz

Which of the following best describes a covalent bond?

• The transfer of electrons from one atom to another

• The sharing of electron pairs between atoms

• The attraction between positive and negative ions

• The movement of free electrons among metal atoms

Which property is most commonly associated with covalent compounds?

• High electrical conductivity in solid state

• High melting and boiling points

• Poor electrical conductivity

• Malleability and ductility

What is a key characteristic of metallic bonding?

• Electrons are shared in pairs between atoms

• Electrons are transferred from one atom to another

• Electrons are delocalized and move freely among metal ions

• Atoms form rigid crystal lattices

Which of the following is an example of a covalent compound?

Which property is typical of metals due to metallic bonding?

• Brittle when solid

• Poor conductor of heat

• Shiny and good conductor of electricity

• Low melting point

How do covalent and metallic bonds differ in terms of electron behavior?

• Covalent bonds involve delocalized electrons; metallic bonds involve shared pairs

• Both involve the transfer of electrons

• Covalent bonds involve shared electron pairs; metallic bonds involve delocalized electrons

• Both involve fixed electrons in a lattice

Which of the following is NOT a property of covalent compounds?

• Usually low melting and boiling points

• Often soluble in water

• Poor conductors of electricity

• Formed by sharing electrons

Which of the following is an application that relies on metallic bonding?

• Table salt for seasoning food

• Water for hydration

• Copper wires for electrical circuits

• Sugar for sweetening

Which statement best compares covalent and metallic bonds?

• Both involve the transfer of electrons

• Covalent bonds form between metals; metallic bonds form between nonmetals

• Covalent bonds involve sharing electrons between specific atoms; metallic bonds involve a 'sea' of delocalized electrons

• Both result in high electrical conductivity

Which of the following molecules is formed by covalent bonding?
