What are non metal ions?
What are non metal ions?
Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements with high ionization energies. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite).

Who found copper?
Copper first came into use as the earliest non-precious metal employed by the Sumerians and Chaldeans of Mesopotamia, after they had established their thriving cities of Sumer and Accad, Ur, al’Ubaid and others somewhere between 5000 and 6000 years ago.

Who found silver first?
Silver has a special place in the history of the elements because it is one of the first five metals discovered and used by humans. The others were gold, copper, lead and iron. Silver objects dating from before 4000 BC have been found in Greece and from slightly later in Anatolia (in modern Turkey).

Is gold man made?
Yes, gold can be created from other elements. But the process requires nuclear reactions, and is so expensive that you currently cannot make money by selling the gold that you create from other elements. Gold is the chemical element with 79 protons in each atomic nucleus.
