Bromide ion is isoelectronic with Krypton.
iron
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.
Po --> Polonium (gains 2 electrons to complete octet rule) Ra --> Radium (loses 2 electrons to complete octet rule) Both end up with 86 electrons, the same amount that Rn (Radon) has.
All of the colors of Kryptonite would include Green Kryptonite, Red Kryptonite, Black Kryptonite, Blue Kryptonite, Gold Kryptonite, White Kryptonite, Yellow Kryptonite, Silver Kryptonite, Pink Kryptonite and Purple Kryptonite.

The question is somewhat flawed. Isoelectric means when two different atoms possess the same electron configuration - i.e. one has to be an ion. As an arbitrary example, H- and He would both be 1s2, and isoelectric. Sulfur and oxygen are not isoelectric, sulfur has a whole extra shell of electrons. If you simply mean, is SO2 a charge molecule? Then no, there is no nett charge on SO2. It is, however, a polar molecule, due to being bent (similar to water).

There is none. Kryptonite is a fictitious substance.
