Krypton is a noble gas. Helium, Neon, Argon, Xenon and Krypton are all notoriously reluctant to form compounds and exist as monatomic atoms. Free krypton would not have a charge.
(That, by the way is a standard chemistry groaner: "There's no charge--it's free!"...right up there with "I'm positive I lost my electron.")
The element that forms an ion with an electronic configuration of Kr and a -2 charge is oxygen. Oxygen gains two electrons to achieve a stable octet configuration, making it isoelectronic with krypton.
The trivalent ion with the electron configuration of Kr 4d^3 is the Yttrium (Y^3+) ion. Yttrium differs from krypton (Kr) by losing three electrons to achieve the electron configuration of Kr 4d^3.
Bromide ion is isoelectronic with Krypton.
The ion that is isoelectronic with Xe is Kr+. Both Xe and Kr+ have the same number of electrons, with 54 electrons each.
The element that forms a +3 ion with the electron configuration Kr 4d^6 is osmium (Os). Osmium typically forms a +3 ion by losing three electrons from its outermost 6s and 5p orbitals, resulting in the electron configuration Kr 4d^6.

To determine the likely ion formed by an element like Kr (krypton), you need to consider its position on the periodic table. Kr is a noble gas located in the far right column, meaning it has a full valence electron shell and is stable. Noble gases do not readily gain or lose electrons, so Kr is unlikely to form an ion.
The element that forms a +3 ion with the electron configuration Kr 4d^6 is osmium (Os). Osmium typically forms a +3 ion by losing three electrons from its outermost 6s and 5p orbitals, resulting in the electron configuration Kr 4d^6.
The ion charge of an NH4 ion is 1.
This is the electrical charge of the ion.
The bromide ion has a 1- charge.
A fluorine ion has a charge of minus one.
The pseudo noble gas electron configuration for cadmium is [Kr] 4d^10 5s^2. Cadmium forms a 2+ cation to achieve a pseudo noble gas electron configuration, where it loses its two 5s electrons and has the electron configuration of [Kr] 4d^10.
The charge of the molybdenum ion is +2.
