When phosphorus achieves a noble gas configuration, it gains three electrons to become the phosphide ion (P³⁻). This allows it to achieve the stable electron configuration of a noble gas, similar to argon.
The pseudo noble-gas electron configuration has the outer three orbitals filled, the s, p and d- s2p6d10 (18 electrons total) and so is fairly stable. Elements that attain this electron configuration are at the right side of the transition metals (d-block). Br-, I-, Se2-
Yes it will as P-3 ion will have the same electron configuration of the noble gas, argon.
None of the noble gases have 5 sublevels. All noble gases have electron configurations that end in an s or p sublevel.
The "Noble gas electron configuration," or the condensed electron configuration, for F is [He] 2s2 3p5.
The number of electron shells depends on the noble gas. The number of shells will be equal to the period in which the noble gas is present.
The electron configuration and noble gas core for Li+ is that of He: Li+: (1s2, 2s0)
Helium's electron configuration is 1s2. Neon's electron configuration is 1s22s22p6. All of the rest of the noble gases, like neon, have the maximum number of electrons in their outermost s and p orbitals (valence shells), which is eight.
Chlorine gains 1 electron to achieve the noble gas electron configuration of argon.
In noble gas notation, you don't have to write the electron configuration up to that noble gas. You simply put the noble gas in brackets [noble gas] and then continue to write the electron configuration from that point. It just makes it shorter and easier to write electron configurations for elements with a lot of electrons.
