w what is the atomic number of Titanium,sodium,chromium,and Nickel,Cobalt,copper,zinc and copper
Answers
Answer:
atomic no ...
Explanation:
The atomic number or proton number of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus.
Copper is a member of a family of metals known as the “coinage metals,” which includes copper, silver, gold, and roentgenium. Because of their softness, coinage metals are easily fashioned into coins. Their comparative rarity and attractiveness, along with their resistance to corrosion, make them compact stores of wealth. However, pure copper is too soft to have structural value, but copper alloys with zinc and tin to form harder brasses and bronzes. Brass and bronze were essential components of the earliest metal tools.
The zinc family consists of zinc, cadmium, mercury, and copernicum. Zinc and cadmium are soft metals that easily oxidize to the +2 oxidation state. Neither of these two metals appears uncombined in nature. Zinc is used in alloys with copper to create a harder metal known as brass. In galvanization, zinc coats iron by oxidizing to form a protective layer of zinc oxide (ZnO) that protects the iron from oxidation. Zinc oxide is much safer than lead oxide, and it is often used in white paint. Since 1982, zinc has been the main metal used in American pennies. It is now used in new organ pipes.
Zinc is an essential trace element for living things and has some germicidal properties, but can be toxic in large quantities. Zinc pennies should never be swallowed.
