C Correct answer
Explanation

Metals readily lose electrons to form positive ions (cations) because they have few valence electrons and low ionization energies. This electron loss is the defining characteristic of metallic behavior in chemical reactions. Oxides, ores, and alloys are compounds or mixtures, not the elements themselves.
