Krypton. In order to find this you have to look at the periodic table. Imagine the Periodic Table is divided into three sections, the first two columns, 1A and 2A, the middle section, the transition metals, and the right side, 3A to 7A.
The first two columns are the s electrons, the middle section is the d electrons, and the right side is the p electrons (oversimplification).
4s2 4p6 means go to the 4th period (row). two s's and 6 p's. Just count it. the 4th element in the p electrons in the 4th period is Krypton.
The correct electron configuration for arsenic is [Ar] 4s2 3d10 4p3.
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 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.
A metalloid in the ground state typically has an electron configuration that exhibits characteristics of both metals and nonmetals. For example, arsenic (a metalloid) has an electron configuration of [Ar] 3d10 4s2 4p3 in its ground state. The varying valence electron shells contribute to the unique properties of metalloids.
I think this question should be read (and written) like:"What is the electron configuration ending in 4s2 4p5 " because 4p2 4p5 is an unusual and even impossible ending of any electronconfiguration.Answer:Bromium, number 35, ends with ... (3d10) 4s2 4p5 (period 4, group 17)
Short answer: [Ar] 3d10 4s2 4p3 OR 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p3
That is Arsenic.
[Ar] 4s2 3d10 4p3
The correct electron configuration for arsenic is [Ar] 4s2 3d10 4p3.
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 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.
[Ar] 4s2 3d10 4p3
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.
A metalloid in the ground state typically has an electron configuration that exhibits characteristics of both metals and nonmetals. For example, arsenic (a metalloid) has an electron configuration of [Ar] 3d10 4s2 4p3 in its ground state. The varying valence electron shells contribute to the unique properties of metalloids.

[Ar] 4s2 3d10 4p3 or 2, 8, 18, 5
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.
