the valence electrons in the copper are lost to the oxygen, creating copper ions. the copper ions (usually) have a charge of +1 or +2. the oxidized copper will have a blue-green hue, called the patina

When copper reacts with oxygen, a chemical change occurs and copper oxide is formed. Copper atoms from the copper surface react with oxygen molecules in the air to produce copper oxide. The appearance of the copper may change, as it can develop a greenish-blue color due to the formation of copper oxide.

Copper reacts with oxygen to form copper oxide the elements involved in this reaction is only copper why?
The oxygen in the reaction is found in the air around you, and forms a synthesis reaction with copper when burned.
Copper plus water plus oxygen gives copper hydroxide is what type of reaction?
2Cu(s) + 2H2O(l) + O2(g) --> 2Cu(OH)2(s) is not a reaction which happens under any normal conditions. If it did we could say the copper is being oxidised.
What happens when add the water to copper carbonate?
No reaction occurs
What happens when copper and ammonia comes into contact?
There is no reaction between them
What happens when you add hydrochloric acid to copper?
Absolutely no reaction happens, that's because copper is less reactive than hydrogen. ;)
What happens to the atoms in copper oxide acid to call it a chemical reaction?
Copper and oxygen atoms form to create copper oxide. This is a synthesis reaction, and it can be created when copper is burned in a fire.
Copper reacts with oxygen to form copper oxide the elements involved in this reaction is only copper why?

What happens when you heat copper in oxygen?
copper oxide
What happens when oxygen reacts with copper?
Copper oxider
What happens to copper when it is affected by wind?
No reaction
Copper plus water plus oxygen gives copper hydroxide is what type of reaction?
2Cu(s) + 2H2O(l) + O2(g) --> 2Cu(OH)2(s) is not a reaction which happens under any normal conditions. If it did we could say the copper is being oxidised.
Can you get the copper oxide from burning copper with oxygen?
Yes, copper oxide can be obtained by burning copper with oxygen. When copper is heated in the presence of oxygen, it undergoes a chemical reaction to form copper oxide. The resulting copper oxide can be collected and used for various purposes.
What type of reaction is this copper plus oxygen equals copper oxide?
It is the direct combination of two elements or oxidation of copper. 2Cu + O2 = 2CuO its a synthesis reaction!
What is the name of the compound formed from the chemical reaction between cooper and oxygen?
Copper Oxide
What happens when add the water to copper carbonate?
No reaction occurs
