Iodine 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p5

.sam. · Answer

Add 1 electron to make it 5p6

.sam. · Answer

And the ion would be
$$I^{-1}$$
Because you're adding an electron

@.Sam. You should explain that just a LITTLE more

jadeishere · Answer

You're doing great, obviously, but, some people don't know why that's a -1 v. +1

@.Sam. Thank you sooooooooooo much for all your help!  I love OpenStudy!

.sam. · Answer

Electron is negative and If you add an electron to an element you will get a negative 1. If you remove an electron from it you will get a plus 1, eg. $I^{+1}$, vice versa
