[Ar] 4s2 3d9
The electron configuration is [Ar]4d10.
[Ar]3d104s1
[Ar]3d104s1
[Ar]3d104s1
[Ar]3d9
I am assuming that the question is for Co2+ ion. and the answer is [Ar] 3d5 4s2
Noble gas notation provides information about the electron configuration of an atom or ion. It indicates the number of electrons in each energy level and the number of valence electrons, which are the electrons in the outermost energy level. This notation helps in understanding the chemical properties and reactivity of an element.
Br - 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5The noble gas notation form isBr- [Ar] 4s2 3d10 4p5Br- ion has 36 electrons and has the same electronic configuration as the noble gas krypton.Its noble gas notation is [Ar] 3d10 4s2 4p6
calcium is normally [Ar] 4s2 if it is a 2+ ion, then it has lost 2 electrons so the configuration is just [Ar]
P3- ion or phosphide ion as the same electron configuration as the noble gas, argon
S2- ion: [Ne]3s23p6

P 3- is the ion with the noble gas configuration.
The charge of a sulfide ion that is isoelectric with its nearest noble gas (argon) is -2. This means that the sulfide ion has gained two electrons in order to have the same electron configuration as the noble gas.
This noble gas is argon (Ar).
oxide ion is isoelectronic with neon.
Argon is isoelectronic with the sulfide ion.
The noble gas neon (Ne), is isoelectronic with N3- ion (not N atom)
