Probably you want the electron cofiguration of uranium: [Rn]5f36d17s2
The ion U4+ lost four electrons.
P3- ion or phosphide ion as the same electron configuration as the noble gas, argon
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.
oxide ion is isoelectronic with neon.
Argon is isoelectronic with the sulfide ion.
Not a neutral Cl atom but the chloride ion Cl- is isoelectronic with the noble gas argon.
P3- ion or phosphide ion as the same electron configuration as the noble gas, argon
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)
P3- or phosphide ion is formed. it has the same number of electrons as the noble gas, argon
Not a neutral Cl atom but the chloride ion Cl- is isoelectronic with the noble gas argon.
I- ion (iodine ion and not iodine) and xenon will have the same number of electrons (54 electrons)
Neon
Argon (Ar)
