1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3.
The electron configuration for a neutral arsenic atom is 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^3.
The correct electron configuration for arsenic is [Ar] 4s2 3d10 4p3.
The electron configuration for arsenic is [Ar] 4s2 3d10 4p3, where [Ar] represents the electron configuration of argon before it. This corresponds to the placement of 33 electrons within the various orbitals of an arsenic atom.
Iron has the electron configuration [Ar]3d64s2.
The element with this electron configuration is arsenic (As), with 33 electrons.
The electron configuration for a neutral arsenic atom is 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^3.
Short answer: [Ar] 3d10 4s2 4p3 OR 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p3
[Ar] 4s2 3d10 4p3
The correct electron configuration for arsenic is [Ar] 4s2 3d10 4p3.
The electron configuration for arsenic is [Ar] 4s2 3d10 4p3, where [Ar] represents the electron configuration of argon before it. This corresponds to the placement of 33 electrons within the various orbitals of an arsenic atom.
Iron has the electron configuration [Ar]3d64s2.
That is Arsenic.
The element with this electron configuration is arsenic (As), with 33 electrons.
Selenium typically gains two electrons to achieve a stable electron configuration, forming the Se2- ion. Arsenic typically loses three electrons to achieve a Noble Gas electron configuration and forms the As3+ ion.
The noble gas configuration for arsenic (As) is [Ar] 3d10 4s2 4p3. This means that it has the same electron configuration as argon (Ar) up to its previous noble gas, with additional electrons filling the 3d, 4s, and 4p sublevels.
The electron configuration of neutral arsenic (As) is [Ar] 4s2 3d10 4p3. Since As3- has gained three extra electrons, the electron configuration becomes [Ar] 4s2 3d10 4p6, as the additional electrons fill the 4p subshell.
Arsenic has a mass number of 33 with an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3. This means that there are 3 valence electrons.
