Electron Configuration This is strange, you'd expect it to have the configuration 3d9 4s2 because the s sub-shell should have been filled by potassium and calcium (1 electron each,) and it … In the periodic table, the elements are listed in order of increasing atomic number Z. Electron configuration of Copper is [Ar] 3d10 4s1. Melting point The temperature at which the solid–liquid phase change occurs. I thought it was the 3d electron, but someone else said it was the 4s electron. Copper is a chemical element with atomic number 29 which means there are 29 protons and 29 electrons in the atomic structure.The chemical symbol for Copper is Cu. Solved: The expected electron configuration for copper should be [Ar]4s^2 3d^9. The copper atom has a radius of 128 pm and a Van der Waals radius of 186 pm. Copper (Cu) has two valences Cu I (cuprous) has one valence electron and Cu II (cupric) has two valence electrons. Top. so we'd expect the electron config for copper to be [Ar]3d^9 4s^2 but the element is more stable by having the 3d orbital full than the 4s so thats why the electron config is [Ar]3d^10 4s^1. Which configuration is apparently more stable? Each additional electron you add usually goes into a 3d orbital. An atom of Copper in the gas phase, for example, gives off energy when it gains an electron to form an ion of Copper. Electronic configuration of Copper, with atomic number 2 9 = 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 4 s 1 3 d 1 0 . b. The ground state electron configuration of ground state gaseous neutral copper is [ Ar ]. The electron configuration is the standard notation used to describe the electronic structure of an atom. Copper has the configuration [Ar]3d10 4s1 (I don't know how to do the fancy superscripts on this editor.) Copper was first discovered by Early Man prior to 9000 BC. Like many of the transition elements, copper has a colored ion. Copper electron configuration So I'm doing some general chem homework and I have to write up the electron configuration of copper. However, the electron configuration for the neutral Cu atom is [Ar]3d 10 4s 1. Copper has an electron configuration of $\ce{[Ar] 3d^10 4s^1}$. Just replace this portion of zinc's electron notation with Argon's chemical symbol in brackets ([Ar].) If you don’t have a chart, you can still find the electron configuration. It is called the "Box and Arrow" (or circle and X) orbital configuration. The number of electrons in each of copper's shells is 2, 8, 18, 1 and its electron configuration is [Ar] 3d 10 4s 1. - helps chemist understanding how elements form chemical bonds.
