Lead - Wikipedia
Lead was used for making water pipes in the Roman Empire; the Latin word for the metal, pluum, is the origin of the English word "pluing". Its ease of working and resistance to corrosion  ensured its widespread use in other appliions, including pharmaceuticals, roofing, currency, and warfare.
Why can’t sodium and calcium be extracted by using …
Rather, it’s the other way round that will work. Sodium and calcium (and even magnesium) will reduce any oxides of carbon into the elemental form. It''s because of their powers as reducing agents which are a lot higher than that of carbon. Carbon c

Metal - Simple English Wikipedia, the free encyclopedia
Metal is hard to pull apart (it has a high tensile strength) or smash (it has a high compressive strength). If you push on a long, thin piece of metal, it will bend, not break (it is elastic ). Except for cesium, copper, and gold, metals have a neutral, silvery color.
Carbon Reduction Method Chemistry Tutorial
The more active (or reactive) a metal is, the more stable the compound it forms and the greater the energy required to produce the metal from its ore. Very active metals ( Group 1 , Group 2 and aluminium) require electrolysis to extract the metal while very inactive metals like gold and silver can occur in nature as the element so require no energy to extract the metal.
