please help i can not find the answere anywhere and y element or group that reacts with copper easily?
Pb - Lead Na Cl - Salt O2 - Oxygen Hg - Mercury F - Fluorine There are many more, however, these will help you
If you want an abridged (too long didn't read) explanation, you're not gonna find one suitable to completely understand. But the best was I can put it, is that all elements react in a way that benefits them energetically (in terms of electrons). Humans manipulate reactions to get particular outcomes, but overall, when one element reacts with another, its because of some form of transferring/sharing/heterolytical/homol... cleavage of electrons. We define elements on the periodic table (primarily by assigning proton number) but simultaneously by electron count (they're equal to each other. go figure!). Just knowing the electron count on one element can give a plethora of ways in which it will react with the electrons of another element. From Organic and Inorganic Chem to Analytical and Physical Chem, I've noticed that the most important factor in reactivity is electron characteristics. (Aside from electronegativity, atom size, basicity/acidity) but even those tie into electron count in SOME way or form
Many elements will react readily with copper. Oxygen will react with copper at any temperature to form an oxide and sulphur will react with copper at any temperature to form a sulphide or sulphate depending on the conditions. Just to clarify from above. Mercury and lead generally will not react with copper unless complexed with many other elements or alloyed in a pure metal compound. NaCl (Salt) is not an element so that doesn't count but copper will react with chlorine to form a chloride and generally will not react with sodium. Copper will react with fluorine as well. There is in fact a trend here. Take a look on wikipedia about the periodic table. You will see that the elements copper primarily reacts with are on the right side of the transition metals. And moreover I can tell you that copper will react more readily with halogens and non-metals that it will with metalloids or other metals. This is because of the strength an atom will hold its electrons with. Copper will more readily give up some of its outer electrons and a halogen (like chlorine) is more willing to take those electrons. Hope this helps! Cheers, Andrew
