What is the element present in chloroplast Mg or Fe or Cu?
Mg is present in the chloroplast.
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.
How many Cu atoms are present in 85mol?
Since the formula unit of copper is a single atom, the answer is 85 X Avogadro's Number or about 5.119 X 1025.
How many 3d electrons does Cu have?
10
How many electrons and protons are found in the Cu plus cation?
29 protons and 27 electrons
Is copper a ferromagnetic element?
No, it can not be converted into a permanent magnet. because Cu has only one unpaired electron.
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.
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.
If copper 2 is paramagnetic what would you classify copper 1 as?
cu+1 will be dimagnetic. cu-[ar] 4s1 3d10 cu+1- [ar] 4s0 3d10 that is for cu+1 d orbital is completely filled , there are no unpaired e-. hence it shows dimagnetism
How many electrons were lost or gained to form Cu plus?
Only one electron lost.
29 electrons period 4?
Copper- CU
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 is the element present in chloroplast Mg or Fe or Cu?
Mg is present in the chloroplast.
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
