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

Answer: -

-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.
