Why does copper conduct electricity better than lead?

Good question. Metals conduct because of the sea of free electrons in the crystal lattice. Metal conductivity depends on how loosely these electrons are bound to the nuclei and how many free electrons. Most other properties of Cu and Fe are comparable. One possible reason is the electron configuration. For Cu, it is (2, 8, 18, 1) for (s,p,d,f) orbitals, respectively. For Fe, (2, 8, 14, 2). Cu has one 4s-orbital electron that can roam freely, because all 3d electrons are paired and act as a shield from the nucleus. Fe's outermost shell is filled with 2 electrons and the 3d shell is not filled. The 3d electrons do not roam as free as 4s electrons. Cu also has more count of electrons than Fe.


How do you get ions of Cu and Br in CuBr?

Cu donates electrons to Br to form CuBr. It is a crystalline compound. The bonds have mixed ionic and covalent characters.


Why hcl is not capable of gaining electron .pls this would be my last question about this topic.why hcl is not capable of gaining electron?

In order for something to act as an oxidizing agent, it itself must be reduced, or put in other terms, it must be able to gain electrons. And for the record, the H2SO4 in order to react with Cu and to oxidize it, must be HOT and CONCENTRATED. Just putting Cu in some H2SO4 will not produce a reaction. The reaction of Cu + H2SO4 is as follows: Cu(s) + 2H2SO4(l) ---> Cu2SO4(s) + SO2(g) + 2H2O(g) ... note the states of each. In this reaction, the S of H2SO4 has gained electrons to form SO2, so it has been reduced and it has oxidized the Cu which went from Cu(s) to Cu^2+ in CuSO4. HCl is not capable of gaining electrons from Cu so it cannot oxidize the Cu.


What happens to H in the CuO H2 to Cu H2O?

In the reaction involving copper(II) oxide (CuO) and hydrogen gas (H2), hydrogen acts as a reducing agent. The hydrogen reduces CuO to metallic copper (Cu), while itself being oxidized to form water (H2O). This process involves the transfer of electrons, where CuO gains electrons to form Cu, and H2 loses electrons to form H2O. Overall, the chemical reaction can be summarized as: CuO + H2 → Cu + H2O.


The reaction CuO plus CO yields Co2 plus Cu is an example of oxidation or reduction or both or neither?

The reaction CuO + CO → CO2 + Cu is an example of reduction because copper(II) oxide (CuO) gains electrons to form copper (Cu). Reduction is the gain of electrons by a species.

If copper 2 is paramagnetic what would you classify copper 1 as?

Copper 1 would be classified as diamagnetic, as it has all of its electrons paired in its orbital. Unlike paramagnetic materials that have unpaired electrons and are attracted to a magnetic field, diamagnetic materials have all paired electrons and are weakly repelled by a magnetic field.


How many 3d electrons does Cu have?

Copper (Cu) has one 3d electron.


How many electrons and protons are found in the Cu plus cation?

The Cu+ cation is formed when a copper atom loses one electron. Therefore, it has one more proton than electrons. So, the Cu+ cation has 29 protons and 28 electrons.


How many electrons were lost or gained to form Cu plus?

One electron was lost to form Cu+ from the neutral Cu atom.


What elements have 29 electrons?

Copper, Cu, has 29 electrons.


What is the net charge of copper atom if it gain two electrons?

Cu(2-) does not exist, because Cu does not gain electrons at all being a metal. When it gives off two electrons Cu(2+) ions are formed.


What is the total number of moles of electrons lost by the copper as it completely reacts with 8 moles of nitric acid?

For the reaction between copper and nitric acid, the balanced equation is: 3Cu + 8HNO3 -> 3Cu(NO3)2 + 2NO + 4H2O Since each mole of Cu loses 2 moles of electrons, and there are 3 moles of Cu in the balanced equation, the total number of moles of electrons lost by Cu is 6 moles (3 moles of Cu x 2 moles of electrons/mole of Cu = 6 moles of electrons).


How many electrons does Cu have?

Copper's atomic number is 29. Thus, copper has 29 protons per atom. To be electrically neutral then, it must also have 29 electrons per atom.


What element only has 29 electrons?

The element with 29 protons (and therefore 29 electrons) is copper.


How many valence electrons do Cooper have?

Copper (Cu) has 2 valence electrons. It is located in the middle group of elements, called Transition Metals, and all transition metals have 2 valence electrons...hope that helped! =D


How many electrons does it take to make 80Cu of charge?

The amount of electrons it takes to make 80CU of charge would come as an equation. CU stands for Coulombs. It would take 4.9932078e+20 electrons for 80 CU of charge.
