Iodine accepts one electron to achieve noble gas configuration. Strontium loses two electrons to achieve noble gas configuration. Nitrogen accepts three electrons to achieve noble gas configuration. Krypton already has a noble gas configuration.
No, iodine has 5 electron shells. It has a total of 53 electrons and its electron configuration is [Kr] 5s2 4d10 5p5, indicating that it has 4 electron shells.
Iodine gains 1 electron to fill it's shell.
Chlorine has 17 electrons, therefore its electronic configuration is: 2, 8, 7
[Kr]
Potassium lose an electron (iodine gain this electron) to form potassium iodide, KI.
Iodine is the element with that configuration.
Iodine accepts one electron to achieve noble gas configuration. Strontium loses two electrons to achieve noble gas configuration. Nitrogen accepts three electrons to achieve noble gas configuration. Krypton already has a noble gas configuration.

Potassium is K1+, and Iodine is I1-. As a result, Potassium iodide is made. It's ionic becuase Potassium has a positive charge, so it needs one more electron to have its orbitals filled. Iodine on the other hand, has an electron that isn't needed. If Iodine can give up its electron, then all of its orbitals will be filled. As a result, iodine gives it's extra electron to the potassium, and they both have filled orbitals. When an electron is being given and accepted, that's called an ionic bond. So Potassium iodide is ionic.
