It's because of the friction between each metal.
A metal and a non metal. Two non metals. A metal and a metalloid.
how do metals react with oxygen
Non metals form ionic bonds with metals. Non metals gain the electrons while metals loose. Alkali metals reacts with halogen family in efficient manner.
No, they will not react when put together. This is because both calcium and copper are electropositive metals. No two electropositive elements or electronegative elements react under normal conditions.
When metals react with other metals, they can form metal alloys. These alloys have different properties compared to the pure metals and are often stronger and more resistant to corrosion. Mixing metals together can also alter their physical and chemical properties.
If you mean what two element types then: Metals and non-metals If not, I do not know what you are asking
Metals loss electrons and nonmetals gain electrons.
Elements from the boron, carbon, pnictogen, chalcogen and halogen families (groups 13 to 17) react with metals.
Au and Pt are some metals which do not react with O.
No, Acids react with metals to form salts.
metals lose electrons when they react with a non-metal
Most metals do not react with water, especially at room temperature. It is easier to state which metals DO react with water. Those would be Li, K, Sr, Ca and Na. Those reacting with hot water (steam) would be Mg, Al, Zn and Cu. Most other metals do NOT react with water.
