any of various opaque, fusible, ductile, and typically lustrous substances that are good conductors of electricity and heat, form cations by loss of electrons, and yield basic oxides and hydroxides; especially : one that is a chemical element as distinguished from an alloy. - Merriam-Webster's online dictionary. In other words, it is a group of elements, not a compound or alloy.
Metals like gold, silver, and copper can be found in a pure form and used straight out of the ground due to their natural occurrence in a native state. These metals require minimal processing for use in various applications.
This is because metals like gold lie at the bottom in the activity series so they are less reactive and are found in the free state, whereas, metals like aluminium, zinc, etc. are found on the top of the activity series so they are highly reactive and are found in the form of compounds.
Whether the elements found in the ground are reactive or not, partly depends on whether there is any other chemical there for them to react with.Gold, Platinum, Tin, and a few others close to the noble metals are less reactive, but even some reactive elements are found (uncommonly) in the native state.Silver is one of the more common ones so found, but Iron and Mercury are also found in the native state.
Metals are highly reactive and are most commonly found in an oxidized state.
Quick and simple answer is that metals are solid and therefore are affected by the gravity of the Earth more than gases. Therefore gases are in the air and solids are on the surface or under the surface of the Earth.

Yes, metals are usually obtained from ores in the ground. But a few metals may be found in their 'native' state. Silver, platinum, tin, and even iron (rarely). And magnesium is comonly refined from sea water. BUT some iron - nickel meteorites do descend from the sky - but probably were part of a previous planet.

Generally non-metals receive the suffix -ide in a compound.
if sodium is in a compound, it will not be in natural state. natural state implies that it is a pure element. ie not a compound

Romann numerals are used: (I), (II)...
Sodium, magnesium, and aluminum are examples of fairly reactive metals that are commonly found as ores in the Earth's crust. These metals can be extracted from their ores through processes such as electrolysis or chemical reactions.
Only a few metals are found in the free state, generally metals react to form for example oxides, sulfides which then may further react. Some found free are gold silver copper and platinum. All of these are relatively unreactive
You cant manufacture using electrolysis, but you can separate metals from their compound state, metals such as aluminium (reactive metals).This is often a very expensive process.Hope this helps!
gold, silver, copper, platinum and some other platinum metals
