Not exactly as asked in the question.
But K+, Ca2+ and Ar all have the same electronic configuration. All will have a total of 18 electrons.
The abbreviated electron configuration for argon is [Ne] 3s^2 3p^6. The [Ne] represents the electron configuration of the noble gas neon, which has the same electron configuration as the inner electrons of argon.
Sulfur needs to gain 2 electrons to have the electon configuration of Argon
The negative ion F has the same electronic configuration as the positive ion Ne. This is because the negative ion F gains an electron to achieve a stable octet configuration, similar to the stable electronic configuration of the noble gas Ne.
When sulfur forms a negative ion, it gains two electrons to achieve a full outer electron shell, making it have the same electron configuration as argon.
The chloride ion (Cl-) has the same electron configuration as argon, which is 1s2 2s2 2p6 3s2 3p6. This is because the chloride ion has gained an extra electron compared to argon, giving it a full outer electron shell.
K+ and argon have the same electron configuration
The element that forms a 2+ ion with the same electronic configuration as Ar is Calcium (Ca). When Calcium loses two electrons, it attains the same electronic configuration as argon by having a full outer shell of electrons.
Considering the normal calcium ion Ca2+ it has the same electronic configuration as the noble gas Argon.
Argon has the same electron configuration as a sodium ion. Sodium ion has lost 1 electron from its outer shell, making its electronic configuration 2, 8. Argon's electronic configuration is also 2, 8 in its outer shell.
The electronic configuration of calcium is 1s2 2s2 2p6 3s2 3p6 4s2. In calcium hydroxide (Ca(OH)2), calcium loses its two outer electrons to form Ca2+ ion, which has the electronic configuration 1s2 2s2 2p6 3s2 3p6.
A calcium ion (Ca²⁺) has lost two electrons, resulting in an electronic structure similar to that of argon (Ar), which has 18 electrons. Both Ca²⁺ and Ar have the same electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶. Therefore, argon is the atom that shares the same electronic structure as a calcium ion.
Argon has the same electron configuration as a potassium ion, as both species have 18 electrons with the electron configuration of [Ne]3s²3p⁶.
1s2, 2s2 2p6, 3s2 3p6 The sulfur ion has 16 electrons but sulfide has a charge of negative 2, increasing its electron count by two for a total of 18 electrons, giving it the same electron configuration as Argon (this means it is also isoelectronic with Argon)
The abbreviated electron configuration for argon is [Ne] 3s^2 3p^6. The [Ne] represents the electron configuration of the noble gas neon, which has the same electron configuration as the inner electrons of argon.
The noble gas configuration for selenium is [Ar] 3d10 4s2 4p4, which means it has the same electron configuration as argon, followed by 4d10 4p4 electrons.
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.
Sulfur needs to gain 2 electrons to have the electon configuration of Argon
