    Q.

    Metallic bonding is...

    answer choices

    The sharing of electrons

    an attraction between oppositely charges ions

    an attraction between positive ions and electrons.

    answer choices
    delocalized electrons
    oxidation number
    chemical bond
    salts
  • Question 10
    30 seconds
    Q. What is the ability of a substance to allow heat, sound, or electricity to flow through it?
    answer choices
    Malleability
    Ductility
    Solubility
    Conductivity
  • Question 11
    45 seconds
    Q.

    Why are metals malleable?

    answer choices

    They are shiny

    The electrons are held tightly within the lattice structure making it strong

    The electrons are delocalized and able to move between the atoms

    The electrons are shared between two metal ions and this holds the atoms together

  • Question 12
    45 seconds
    Q.

    Why do metallic compounds conduct electricity as solids?

    answer choices

    core electrons are mobile, allowing electricity to flow through the metal

    valence electrons are mobile, allowing electricity to flow through the metal

    protons are mobile, allowing electricity to flow through the metal

    the metal cations are mobile, allowing electricity to flow through the metal

  • Question 13
    30 seconds
    Q.

    Metals have...

    answer choices

    High meting points because metallic bonds are weak

    Low melting points because metallic bonds are weak

    High melting points because metallic bonds are strong

    All of the above
