The dot structure for IO4 starts with the I atom in the center. from this, there are three doubly bonded O atoms and one singly bonded O atom. The O atom has three pair of dots and the others have two pair of dots. The structure is then bracketed and noted with a 1- superscript.

The electrons in the valence shell are shown in the Lewis structure of an atom by dots. Additionally, if it contains bonds, they are shown by dashes.

Lewis dots are concerned with electrons in the outer most shell of an atom. This means that no matter how many electrons an element contains, Lewis dots will never number higher than eight.
The correct Lewis Structure for the oxygen atom will be an 'O' with two dots above and below, with one dot on the left and on the right sides.
