The ground state electron configuration for copper (Cu), which has an atomic number of 29, is [Ar] 3d^10 4s^1. This configuration reflects the filling of the 3d subshell with ten electrons and one electron in the 4s subshell. The stability of the fully filled 3d subshell contributes to the unique electron arrangement of copper compared to its neighboring elements.
What else can I help you with?
Give the ground-state electron configuration for copper (Cu) using noble-gas shorthand.?
The ground-state electron configuration for copper (Cu) using noble-gas shorthand is [Ar] 3d¹⁰ 4s¹. This notation indicates that copper has a total of 29 electrons, with the argon (Ar) core accounting for the first 18 electrons, followed by a fully filled 3d subshell and one electron in the 4s subshell.
What the ground state and excited state term arising for cu?
The ground state term for copper is a half-filled 3d subshell with an electronic configuration of [Ar] 3d^10 4s^1. The excited state term can arise when an electron transitions to a higher energy level, resulting in configurations like [Ar] 3d^9 4s^2. This creates various possible excited state terms depending on the location of the excited electron within the 3d orbital.
Why do elements go from ground state to excited state?
Elements go from the ground state to the excited state if some form of energy is supplied. Otherwise, they stay in the ground state.
Is copper divalent?
Copper can exist in multiple oxidation states, primarily as monovalent (Cu¹⁺) and divalent (Cu²⁺). While Cu²⁺ is the more stable and common form in many compounds, copper itself is not exclusively divalent, as it can also exist in the monovalent state. Thus, while copper can be divalent, it is not limited to that oxidation state.
What element ground state is different from predicted?
chromium (Cr) and copper (Cu)chromium has 4s1,3d5 instead of 4s2,3d4 and copper has 4s1,3d10 instead of 4s2, 3d9
What is the ground-state electron configuration for copper (Cu) using noble-gas shorthand?
The ground-state electron configuration for copper (Cu) using noble-gas shorthand is Ar 3d10 4s1.
What Element has lowest atomic number that contains a complete d sub shell at ground state?
The element with the lowest atomic number that has a complete d subshell at its ground state is Titanium (element 22). In its ground state, Titanium's electron configuration is [Ar] 3d2 4s2, which means the 3d subshell is completely filled with 2 electrons.

What state of matter is the cu(no3)2?
Cu(NO3)2 is typically a solid state of matter at room temperature. It is a compound that is commonly seen as a white to pale blue crystalline powder.
What the ground state and excited state term arising for cu?
The ground state term for copper is a half-filled 3d subshell with an electronic configuration of [Ar] 3d^10 4s^1. The excited state term can arise when an electron transitions to a higher energy level, resulting in configurations like [Ar] 3d^9 4s^2. This creates various possible excited state terms depending on the location of the excited electron within the 3d orbital.
What is the oxidation number in Cu2S?
The oxidation number of Cu in Cu2S (copper sulfide) is +1. This is because the overall charge of the compound is 0 and there are two Cu atoms each with an oxidation state of +1.
What has a higher energy ground state or excited state?
ground
What are minerals plants obtain from the ground?
N, P, K, Fe, Mg, Zn, S, Cu etc.
Why do elements go from ground state to excited state?
Elements go from the ground state to the excited state if some form of energy is supplied. Otherwise, they stay in the ground state.

What is the lowest allowable energy state of an atom?
The lowest allowable energy state of an atom is called the ground state. In this state, the electron occupies the energy level closest to the nucleus, known as the 1s orbital in the case of hydrogen. The electron has the lowest energy and is most stable in the ground state.
