How many atoms are there in a molecule of copper?
Copper is normally encountered as metal which is a giant lattice of atoms.
Why is copper a metal?
Copper is a metal due to its chemical properties. It has a high electrical conductivity, malleability, ductility, and luster which are characteristic of metals. Additionally, copper atoms have loosely held outer electrons that allow them to easily form metallic bonds with other copper atoms, resulting in a metallic structure.
What happens if you put copper metal into a solution of aluminum sulfate?
Nothing will happen. Displacement reaction only happens when the element is more reactive than the salt solution. An example will be the otherwise. If you put aluminum metal into a solution of Copper (II) Sulfate. The aluminum metal will displace copper metal and you will have a solution of Aluminum Sulfate and copper metal. As long the element you put into the salt solution is more reactive than the cation of the solution, it will displace the metal.
What happens when iron is dipped in copper sulphate solution and why?
When Iron metal is dipped into a solution of copper sulfate a REDOX reaction occurs in which the Copper is reduced (gains electrons) and the iron is oxidised (loses electrons). When this happens, the iron metal becomes iron ions and the copper ions in the solution become copper metal. Cu2+(aq) + 2e- --> Cu(s) Fe(s) -->Fe2+(aq) + 2e- This occurs because the iron is a more active metal than copper, and as a general rule of thumb, a more reactive metal will displace a less reactive metal from solution. This principle underlies the action of the sacrificial electrode.
How are the silver and copper atoms held together?
Metals are giant structures of atoms held together by metallic bonds. "Giant" implies that large but variable numbers of atoms are involved - depending on the size of the bit of metal. Most metals are close packed - that is, they fit as many atoms as possible into the available volume. hope this helps :)
Where is the excess copper from after adding zinc to copper sulfate?
The "excess" metallic copper produced by adding zinc metal to a copper sulfate solution comes from exchanging zinc atoms from the metal for copper atoms from the copper sulfate solution. During the reaction, the zinc atoms are ionized to cations and the copper cations from the solution are reduced to neutral atoms.

Why is copper best conductor of eletricity?
Electricity passes through atoms in the metal and the closer together they are the better the metal is as a conductor. In copper the atoms are closer together than they are in any other metal.

What redox reaction would most likely occur if silver and copper metal were added to a solution that contained silver and copper ions?
The most likely redox reaction that would occur is the reduction of silver ions to silver metal by copper atoms, with copper atoms oxidizing to copper ions in the process. This reaction would lead to the displacement of silver ions by copper atoms in the solution.
What happens to the resistance of metals as they get hot?
The electrical resistance in a common piece of metal such as copper wire would increase. This happens because as temperature increases the atoms of the metal vibrate quicker and to a larger extent resulting in a greater number of collisions for electrons moving along the metal.
Is copper metal a compound or an element?
Copper metal is an element. It is categorized as a pure substance made up of only one type of atom, specifically copper atoms.
What is the oxidation number for copper metal?
The oxidation number for copper metal is 0. This is because copper atoms in their elemental form have a neutral charge, with an equal number of protons and electrons.
What substance is formed on a copper metal surface while in a silver nitrate solution?
A layer of silver will form on the copper metal surface through a displacement reaction, where the copper atoms are replaced by silver atoms in the silver nitrate solution. This reaction is known as a redox reaction, where copper is oxidized and silver is reduced.
Why can iron be used to get copper from copper sulfate solution?
Iron can displace copper in a chemical reaction because it is a more reactive metal. When iron is added to a copper sulfate solution, the iron atoms will replace the copper atoms in the solution, forming iron sulfate and causing copper metal to be deposited. This process is known as a displacement reaction.
What happens when copper metal reacts with potassium cyanide?
Copper metal is less reactive than potassium so it will not react with potassium cyanide.
What substance is formed when you mix sulphur and copper?
You get copper sulphide, because a metal and a non-metal are reacting.
