Neutral arsenic has 33 protons and 33 electrons. The first 33 electron orbitals are filled as 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3. The superscripts above these subshells is the number of electrons in them.
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.
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.
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.
The electron configuration of arsenic is [Ar] 3d10 4s2 4p3. This means that arsenic has 2 electrons in its outermost shell (4s2 4p3) and belongs to the p-block of the periodic table.
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 shorthand electron configuration for arsenic (As), which has an atomic number of 33, is [Ar] 4s² 3d¹⁰ 4p³. This notation indicates that arsenic has the same electron configuration as argon (Ar), plus two electrons in the 4s subshell, ten electrons in the 3d subshell, and three electrons in the 4p subshell.
In beryllium (Be), the valence subshell occupied by electrons is the 2s subshell, with the electron configuration being 1s² 2s². In arsenic (As), the valence subshells are the 4s and 3d subshells, with the electron configuration being [Ar] 4s² 3d¹⁰ 4p³. Therefore, beryllium has electrons in the 2s subshell, while arsenic has electrons in the 4s and 4p subshells.
The noble gas configuration for arsenic (As), which has an atomic number of 33, is [Ar] 3d¹⁰ 4s² 4p³. This notation indicates that arsenic has the electron configuration of argon (Ar) followed by ten electrons in the 3d subshell, two in the 4s subshell, and three in the 4p subshell.
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.
Short answer: [Ar] 3d10 4s2 4p3 OR 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p3

The electron configuration of arsenic is [Ar] 3d10 4s2 4p3. This means that arsenic has 2 electrons in its outermost shell (4s2 4p3) and belongs to the p-block of the periodic table.
The spdf notation of arsenic in the +3 oxidation state (As³⁺) is [Ar] 3d¹⁰ 4s² 4p³. In its neutral state, arsenic has the electron configuration of [Ar] 3d¹⁰ 4s² 4p³, but the removal of three electrons typically occurs from the 4p and 4s orbitals when it forms As³⁺. Thus, for As³⁺, the notation reflects the loss of these outer electrons while retaining the filled 3d subshell.
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 chemical element arsenic, or As, is in group 15, period 4. Thus its electron configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p3. Since its outermost shell is 4, arsenic has 5 valence electrons.
