An iodine ion contains 53 protons, 52 neutrons, and 54 electrons. what is the net charge of the ion?

-

-1

Explanation: -

There are 53 protons in the given iodide ion.

Each proton carries +1 positive charge.

So net positive charge = 53 x +1 = +53.

There are 54 electrons in the iodide ion.

Each electron has - 1 negative charge.

So net negative charge 54 x -1 = -54

Net charge= +53 - 54

= -1

Thus an iodide ion has - 1 net charge on the ion.
