Simply because they exist in their natural state. Most elements are naturally found in compounds (ores, minerals) and must be processed to access the actual elements.
Copper and Silver are both elements. However the copper and silver objects you find in everyday life are unlikly to be 100% pure copper or silver. These objects will be made with copper or silver alloyed to other metals to improve its properties or decrease its cost.
zinc was one of the elements found in 1526
The elements Copper (Cu) and Silver (Ag) may be in the same group, but they are completely different elements. This means they have a different amount of electrons. Copper has 29 electrons, wheras Silver has 47.
Copper and silver are both metallic elements, but they have different properties. Copper is reddish-brown in color, while silver is shiny and white. They also have different melting points and densities.
Gold, silver, and copper belong to the class of minerals known as native elements. These minerals occur in nature in their pure form and are not chemically bound to other elements.

Copper
The first five elements discovered were gold, copper, silver, lead, and iron. These elements have been known since ancient times due to their distinct properties and uses.

silver, copper. copper can be replaced by germanium, zinc, platinum
The metals silver, copper and nickel are elements. It is brass that is an alloy, and copper and zinc are what make it up.
Not known; some chemical elements as gold, copper, silver, mercury, sulfur, carbon, etc. are known from prehistoric times.
The elements platinum, silver, and copper are similar to gold.
Gold, Silver and Copper belong to the native elements mineral group.
no way to say as it was known before earliest civilization.
The elements Copper (Cu) and Silver (Ag) may be in the same group, but they are completely different elements. This means they have a different amount of electrons. Copper has 29 electrons, wheras Silver has 47.
Gold follows copper and silver in order, in the same vertical column in the periodic table of the elements.
