What are metals?
A metal is a material which is when prepared freshly, polished, or fractured, shows the lustrous appearance, and also conducts electricity and heat relatively well through them. Metals are typically ductile in nature i.e., can be deformed into a thin wire and malleable. All of these properties are the result of the metallic bond which is present between the atoms or molecules of the metal.
Metals are the cationic elements. These are positively charged due to the loss of electrons from the valence shells. There are about 70 metals out of 92 natural elements present in the periodic table.
Therefore, the correct option is D.
