Is this electron configuration 1s22s22p63p4 correct?
From the Periodic Table the first part of the configuration gives 1s22s22p6 neon (Ne) but after that an outer-shell appears to be missing, could it be possibily 3s23p4 if that's the case the element is sulphur (S)
S: [Ne] 3s23p4
The element with this electron configuration is calcium (Ca), which has 20 electrons.
The element with this electron configuration is arsenic (As), with 33 electrons.
The electron configuration of the element with the atomic number 39 (yttrium) is: [Kr]4d15s2.
Noble Gas Notation: [Ar] 3d10 4s2 Electron Configuration: 1s2, 2s22p6, 3s23p6, 4s23d10 Electron Arrangement in Shell: 2, 8, 18, 2
Lithium (Li) has the electron configuration 1s2 2s1.
That is Arsenic.
Bromine
The element with this electron configuration is calcium (Ca), which has 20 electrons.
The element with this electron configuration is arsenic (As), with 33 electrons.
The electron configuration of the element with the atomic number 39 (yttrium) is: [Kr]4d15s2.
Noble Gas Notation: [Ar] 3d10 4s2 Electron Configuration: 1s2, 2s22p6, 3s23p6, 4s23d10 Electron Arrangement in Shell: 2, 8, 18, 2
Lithium (Li) has the electron configuration 1s2 2s1.
That's the electron configuration of an atom of molybdenum. Atomic number, 42.
The electron configuration for bromine is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5.
The electron configuration provided corresponds to the element iodine (I).
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.
The correct electron configuration for arsenic is [Ar] 4s2 3d10 4p3.
