Thetwo nonmetallic properties of graphite, which are used to explain why pencils conduct electricity, are to be classified. Concept Introduction: Metals are considered flexible, radiant, tensile substances that are good conductors of heat and electricity. They make positive ions (cations) by losing electrons. Nonmetals are considered brittle, are considered to have high electronegativities, and high ionization energies. Suchsubstances are good insulators of heat. The ability of gaining electrons easily is found in most nonmetals. They make negative ions (anions) by gaining electrons.

Interpretation:

Thetwo nonmetallic properties of graphite, which are used to explain why pencils conduct electricity, are to be classified.

Concept Introduction:

Metals are considered flexible, radiant, tensile substances that are good conductors of heat and electricity. They make positive ions (cations) by losing electrons.

Nonmetals are considered brittle, are considered to have high electronegativities, and high ionization energies. Suchsubstances are good insulators of heat. The ability of gaining electrons easily is found in most nonmetals. They make negative ions (anions) by gaining electrons.
