Metallic Bonding
Chemistry ⇒ Chemical Bonding and Structure
Metallic Bonding starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Metallic Bonding.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
A student claims that metals are brittle because their atoms are held together by strong bonds. Is this claim correct? Explain your answer.
Describe how metallic bonding explains the high melting points of most metals.
Describe how the structure of an alloy differs from that of a pure metal.
Describe the arrangement of atoms and electrons in a metallic solid.
Describe the difference between metallic bonding and ionic bonding.
Explain why alloys are often harder than pure metals.
Explain why metals are good conductors of electricity.
A student claims that metals are brittle because their atoms are held together by strong bonds. Is this claim correct? Explain your answer.
Which of the following best describes metallic bonding? (1) The sharing of electron pairs between atoms (2) The electrostatic attraction between positive metal ions and delocalized electrons (3) The transfer of electrons from one atom to another (4) The attraction between oppositely charged ions
Which of the following best describes the movement of electrons in a metallic bond? (1) Fixed in place (2) Shared between two atoms (3) Free to move throughout the structure (4) Transferred to nonmetals
Which of the following best explains why metals are malleable? (1) The presence of covalent bonds (2) The ability of layers of atoms to slide over each other (3) The formation of ions (4) The presence of nonmetal atoms
Which of the following is a reason why alloys are used instead of pure metals? (1) Alloys are more reactive (2) Alloys are usually harder and stronger (3) Alloys are less conductive (4) Alloys are more malleable
Fill in the blank: In metallic bonding, the positive ions are arranged in a ________ structure.
Fill in the blank: Metals are ________ because the layers of atoms can slide over each other without breaking the metallic bond.
Fill in the blank: The ________ electrons in a metal are responsible for its ability to conduct heat and electricity.
Fill in the blank: The ________ model is used to explain the properties of metals such as conductivity and malleability.
True or False: All metals have the same number of delocalized electrons per atom.
True or False: In metallic bonding, electrons are free to move throughout the structure.
True or False: Metallic bonding can occur in both pure metals and alloys.
True or False: Metallic bonding involves the attraction between positive ions and a sea of delocalized electrons.
