[Ar]3d104s24p3
The noble gas configuration of arsenic is [Ar] 3d^10 4s^2 4p^3.
No, arsenic is not a noble gas. Noble gases such as helium, neon, argon, krypton, xenon, and radon are chemically inert elements found in Group 18 of the periodic table. Arsenic, on the other hand, is a metalloid element found in Group 15.
The noble gas core for fluorine is neon. So the electron configuration for fluorine with a noble gas core is [Ne] 3s^2 3p^5.
[He]
The element, plutonium
The chemical symbol is As. The atomic number is 33.
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 and noble gas core for Li+ is that of He: Li+: (1s2, 2s0)
The noble gas core notation for Se-2 is [Kr] 4d10 5s2 5p6.
The noble gas core notation for Calcium is [Ar]4s2. This notation represents the electron configuration of Calcium by using the nearest noble gas (Argon) as a reference.
