Copper Electron Configuration Correct (Cu) The configuration notation allows scientists to easily express and explain how electrons are organized around an atom's nucleus. This facilitates understanding and prediction of how atoms interact to create chemical bonds. The electronic structure of an element can be expressed using a simple diagram called an electron energy level diagram or electron shell diagram. These diagrams show the number of electrons in each orbital that is available for interaction with other particles such as photons, neutrons, and electrons.
The location of electrons in orbitals determines their ability to react with other elements or molecules. For example, if an electron is placed in an orbital that is not involved with other atoms/molecules, it cannot participate in any chemical reaction. On the other hand, if an electron is placed in an orbital that is already occupied by another electron, then this electron will be unable to participate in any chemical reaction. It is only when electrons are placed in empty orbitals that chemical reactions can occur.
In conclusion, the electron configuration of copper is correct because it has two electrons in its 1s orbital, one electron in its 2s orbital, and no electrons in its 3d or 4f orbitals.
Copper is a chemical element with the atomic number 29 and the symbol Cu (from Latin: cuprum).
|Oxidation states||−2, 0, +1, +2, +3, +4 (a mildly basic oxide)|

Cu has the electronic configuration 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d9 ([Ar] 4s2, 3d9), whereas Cu2+ has the electronic configuration [Ar], 3d9. Thus, Cu and Cu2 have different electronic configurations.
In general, elements with an electronic configuration of 1s2 are called sp metals (i.e., soft metals); those with 1s2 and also 2s2 are called dsp metals (i.e., double-soft metals). Elements with only 2s2 electrons are called hard metals. The suffix -ide means "without," so elements that have 3d or 4s electrons are called non-metals.
Elements with the electronic configuration [Ne] 3s2 3p6 3d10 are called lanthanoids, after Lanthanum; those with [Kr] 4s2 4p6 4d10 are called actinoids, after Actinium.
The last two electrons in an atom's valence shell are usually filled by the opposite spin electrons in the outermost orbital of the corresponding element. These electrons are called "free" because they are not involved in chemical bonding. However, there are exceptions to this rule. For example, O has a full octet except for one electron in its outermost orbital which is shared with another oxygen molecule.
Mol. Copper (Cu2) is a blue-white metallic element that is malleable when cold and hardens into a shiny, silver-white metal when heated to 1,100 degrees Fahrenheit (567 degrees Celsius). It is the most common copper compound and a component of blood. An adult male has about 80 mg of copper in his body; a female, 70 mg.
Atomic number 30; atomic mass 63.5084. Copper is a p-block element with an inert noble gas-like core. Its only real chemical property is its affinity for other elements, which results in many compounds being found in nature and used in technology. The most important use for copper is in wiring because it allows electricity to flow without resistance. Other uses include heat-producing devices like heaters and hot-water tanks, as well as electrical components such as transistors and capacitors.
Copper has been used for thousands of years for everything from ceremonial offerings to household items. It was one of the first metals known to mankind and is still in widespread use today.
In chemistry, copper(II) oxide is the most abundant form of copper on earth.
The Cu2+ ion has 27 electrons. Because copper has an atomic number of 29, its nucleus will likewise have 29 protons. Therefore, the Cu2+ ion is a doubly-charged ion.
Cu2+ also has a full outer shell with 32 electrons. Therefore, it is a fully-filled electronic shell and is paramagnetic.
There are 26 electrons in the first subshell and 2 electrons in the second subshell. Thus, the configuration of Cu2+ is [Xe] 4f14.
The angular momentum of electrons in their lowest energy level is 1/2 electron quantum unit (quanta). The total angular momentum of the electron cloud is therefore 0. The spin of the copper nucleus is 1/2. So, both copper atoms together have zero spin.
Copper has one valence electron more than zinc. So, copper is an electropositive metal while zinc is electronegative.
This means that copper is able to attract electrons from other metals by electrostatic attraction which leaves zinc without any charge. At least, that's how I understand it!
