Iodine gains 1 electron to fill it's shell.
iodine gains 1 electron so it can have a complete outer shell of 8 valence electrons
Only one electron is gained by iodine.

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.
Chlorine has 17 electrons, therefore its electronic configuration is: 2, 8, 7
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.
I- ion (iodine ion and not iodine) and xenon will have the same number of electrons (54 electrons)
Every halogen has the capacity to accept one electron from a sodium atom and to thereby achieve a noble gas electron configuration of eight valance electrons. The halogens are fluorine, chlorine, bromine, iodine, and astatine.
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.
It must gain one electron to achieve a noble gas electronic structure, just like other halogens.
Chlorine has 17 electrons, therefore its electronic configuration is: 2, 8, 7
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 is the element with that configuration.
[Kr]
Barium loses electrons to obtain a stable octet, like any other metal.
Iodine is reactive because it has 7 valence electrons and is unstable. It needs one more electron to get 8, which would give it a noble gas configuration, and which would make the iodine atom stable. Iodine reacts with other elements in order to gain the needed electron and therefore become stable.
iodine has 7 electrons in the valence shell. and needs one more electron to attain stable noble gas configuration. So it gains one electron and forms iodide ion with charge of -1.
Seven valence electrons in iodine.
