Co2+ has 25 electrons with the configuration: [Ar] 4s2 3d5
no its [Ar]3d^7
Se2- 1s22s22p63s23p64s23d104p6
The electron configuration of selenium (Se) is [Ar] 3d10 4s2 4p4. To form a 2- ion, two electrons will be removed from the outermost shell, which is the 4p subshell. Therefore, the electron configuration of Se2- is [Ar] 3d10 4s2.
The fluoride ion has the same electron configuration as a neon atom. This is because fluoride has gained an extra electron compared to a neutral fluorine atom, resulting in a full valence shell with 8 electrons. Therefore, the electron configuration of a fluoride ion is 1s2 2s2 2p6.
Oxide ion (O²⁻) has the electron configuration of a noble gas neon (Ne), which is 1s² 2s² 2p⁶.
No, the electron configuration for an ion is not always the same as that of its nearest noble gas. When an atom loses or gains electrons to form an ion, its electron configuration changes. For example, a sodium ion (Na⁺) has the electron configuration of [Ne], which is the same as neon, but a chloride ion (Cl⁻) also has the same configuration as argon ([Ar]). Thus, while some ions can have configurations similar to noble gases, this is not universally true for all ions.
The electron configuration for the Co2 ion is Ar 3d7.
The electron configuration of a V3 ion is Ar 3d2.
The electron configuration of the Co2 ion is Ar 3d7.
The electron configuration of an Sc2 ion is Ar 3d1 4s0.
The electron configuration of boron is 1s2 2s2 2p1. When boron becomes an ion, it typically loses its outer electron to achieve a stable electron configuration. Therefore, the electron configuration of a boron ion is typically 1s2 2s2.
The electron configuration of an Fe ion is 1s2 2s2 2p6 3s2 3p6 3d6.
The ground-state electron configuration for the V3 ion is Ar 3d2.
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
1s2 2s2 2p6 is the electron configuration of the fluoride ion. It has a complete octet and is isoelectronic with neon. Before it becomes an ion, it is 1s2 2s2 2p5 Then it gains an electron and has a negative charge.
The electron configuration of a Copper(II)ion is [Ar]4s0 3d9.
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
The electron configuration of a chromium (Cr) 3 ion is Ar 3d3 4s0.
