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.

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.

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).


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.


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.


What is an element with 29 electrons?

An element with 29 electrons is copper (Cu). It has 29 protons and 29 electrons in its neutral state. Copper is a metal that is commonly used in electrical wiring and plumbing due to its excellent conductivity and resistance to corrosion.
