The characteristic of metals is that they have one to three valence electrons. (OPTION A)

PROPERTIES OF METALS-

• Metals are present on the left side of the periodic table and are highly reactive in nature.
• Metals are sonorous, malleable, ductile, and conduct electricity and heat.
• The valence shell generally contains 1 to 3 electrons, therefore, possessing low ionization energy.
• Metals react vigorously and lose electrons to form cations.
• Metals have low electron affinity so the electrons are shared with the other elements of high electron affinity to form the compound.
• The Metal reacts with water to metal hydroxide releasing hydrogen gas.
• Metals react with air to form metal oxide.
