[Kr]4d6 ion has 42 electrons. As it is a 3+ ion, the parent atom would have 45 electrons. This would make it Rhodium Rh.
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.
Rhodium (Rh) forms a 3 plus ion that has the electron configuration Kr4d6. Rhodium has oxidation states of 2,3 and 4, so it can loan out 2, 3 or 4 electrons depending on the circumstances of a chemical reaction.
The element with an electron configuration of Xe 4f14 corresponds to the element Gadolinium (Gd) with atomic number 64. When it forms a 4+ ion, it loses its 4 outer shell electrons, ending up with a stable electron configuration.
The element that forms an ion with an electronic configuration of Ar with a -2 charge is oxygen (O). When oxygen gains two electrons, it achieves a stable electron configuration similar to argon.
The electron configuration of a chromium (Cr) 3 ion is Ar 3d3 4s0.

When phosphorus forms an ion, it typically gains three electrons to achieve a stable electron configuration. This results in the formation of a phosphide ion with a 3- charge.
When fluorine forms an ion, it gains one electron to achieve a stable electron configuration, becoming a fluoride ion with a charge of -1.

Adding one electron gives the chloride ion which has an octet (it achieves the same electron configuration as argon.
Chlorine (Cl) in the 3rd period can form a -1 ion by gaining an electron to achieve a full outer electron shell (electron configuration of 2,8).
The number of protons and neutrons does not change when an ion forms.
Chlorine can form both positive and negative ions. As an element, chlorine typically forms a negative ion (Cl^-) by gaining one electron to achieve a stable electron configuration. However, in certain compounds, chlorine can also form a positive ion (Cl^+) by losing an electron.
