P3–: From Table 2.2, the electron configuration for an atom of phosphorus is 1s22s22p63s23p3. In order to become an ion with a minus three charge, it must acquire three electrons—in this case another three 3p. Thus, the electron configuration for a P3– ion is 1s22s22p63s23p6.

[Ar] 4s2 3d10 4p3 is the electron configuration of a(n) atom. Which is the correct ground state electron configuration for silver? At maximum, an f-subshell can hold ____ electrons, d-shell can hold ____ and p-shell can hold ____ electrons. Which 2 elements have the same ground state electron configuration?

The inner shells of this species has the noble gas, Argon (Ar) configuration while its valence configuration is 3d².

2s2.2p3

The ground state electron configuration of ground state gaseous neutral caesium is [Xe]. 6s1 and the term symbol is 2S1/2.

[Xe] 6s² 4f¹⁴ 5d⁴

1 Answer. There are four unpaired electrons in the 5d sublevel (subshell).

Silver atoms have 47 electrons and the shell structure is 2.8. 18.18. 1. The ground state electron configuration of ground state gaseous neutral silver is [Kr].

Now, you have to be a little careful with silver because it is a transition metal, which implies that the occupied d-orbitals are actually lower in energy than the s-orbitals that belong to the highest energy level. The thing to remember here is that in silver’s case, the 4d orbitals will be completely filled.

Explanation: Ag+ is more stable than Ag2+ Cation due to the complete Ag+ configuration. An oxidizing agent always tends to accept the electrons. It is extremely volatile and therefore easily accepts electrons to achieve a more stable + 1 oxidation state.

Iron is almost always encountered in the oxidation states 0 (as in the metal), +2, or +3. Iron(III) is usually the most stable form in air, as illustrated by the pervasiveness of rust, an insoluble iron(III)-containing material.
