The element scandium (atomic number 21) has the electron configuration [Ar] 3d1 4s2
Actually the correct configuration is [Ar] 4s2 3d1
this is because d comes after s in the ladder
The ladder goes as follows:
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p
The electron configuration of scandium (Sc) is Ar 3d1 4s2.
Electronic configuration of scandium: [Ar]3d1.4s2
The electron configuration for scandium is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^1. Therefore, the three highest-energy electrons in scandium are in the 3d orbital, and the electron notation for these three electrons is 3d^1.
The element with one 3d electron is manganese (Mn), which has the electron configuration [Ar] 3d^5 4s^2.
This electron configuration belongs to the element chromium, which has the atomic number 24. Chromium is a transition metal element.
The electron configuration of scandium (Sc) is Ar 3d1 4s2.
The noble gas electron configuration of scandium is [Ar] 4s2 3d1. Scandium has 21 electrons, and the noble gas configuration represents the nearest noble gas to scandium, which is argon with 18 electrons.
The electron configuration of scandium is: [Ar]3d1.4s2.
Electronic configuration of scandium: [Ar]3d1.4s2
The noble gas notation of scandium is [Ar] 3d1 4s2, where [Ar] represents the electron configuration of the noble gas argon. Scandium has 21 electrons, with the electron configuration of [Ar] 3d1 4s2.
It is [Ar] 3d1 4s2
Scandium (Sc) has an atomic number of 21, which means it has 21 electrons. Its electron configuration is [Ar] 3d¹ 4s². In this configuration, there is one unpaired electron in the 3d subshell, as the 4s subshell is fully paired. Therefore, scandium has one unpaired electron.
The electron configuration for scandium is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^1. Therefore, the three highest-energy electrons in scandium are in the 3d orbital, and the electron notation for these three electrons is 3d^1.
The element with one 3d electron is manganese (Mn), which has the electron configuration [Ar] 3d^5 4s^2.
No, scandium is not an alkali metal. It is actually classified as a transition metal due to its electron configuration and position on the periodic table.
This electron configuration belongs to the element chromium, which has the atomic number 24. Chromium is a transition metal element.
Scandium is typically found as a cation with a charge of +3, as it tends to lose three electrons to achieve a stable electron configuration.
