Well, all the halogens have 7 valence electrons, the ones in the outermost shell, so elements like fluorine, iodine, and chlorine all need 1 electron to fulfill their octet and become stable.
Iodine gains one electron to achieve a noble gas electron configuration. Its electron configuration is [Kr]5s²4d¹⁰5p⁵, and by gaining one electron, it attains the stable configuration of [Kr]5s²4d¹⁰5p⁶, which is similar to the noble gas xenon.
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.
[Kr]

The element with the electron configuration Kr 5s2 4d10 5p5 is iodine, which has 53 electrons in total. The electron configuration indicates that iodine has 7 valence electrons in its outermost shell, which is in the 5p subshell.
Well, all the halogens have 7 valence electrons, the ones in the outermost shell, so elements like fluorine, iodine, and chlorine all need 1 electron to fulfill their octet and become stable.
The ground state electron configuration of iodine is [Kr]5s^2 4d^10 5p^5. The largest principle quantum number in this configuration is 5, corresponding to the outermost energy level where the valence electrons are located.
Iodine has 7 electrons in its outer most shell. It completes its valence shell by obtaining one electron to form iodide ion.
Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine
Seven
Barium loses electrons to obtain a stable octet, like any other metal.
No, iodine has four electron shells, marked as "K", "L", "M", and "N". The number of electron shells is determined by the electron configuration of an element.
Iodine has one unpaired electron in its ground state.

Iodine gains one electron to achieve a noble gas electron configuration. Its electron configuration is [Kr]5s²4d¹⁰5p⁵, and by gaining one electron, it attains the stable configuration of [Kr]5s²4d¹⁰5p⁶, which is similar to the noble gas xenon.
Bromine has a higher electron affinity than iodine. This is because bromine has a smaller atomic size, resulting in a stronger attraction for electrons compared to iodine.
