# How many protons and electrons are in an iodide ion?

## How many protons and electrons are in an iodide ion?

53 protons
I– (iodide) ions have 53 protons and 54 electrons. The composition of the nucleus for both cations and anions is the same as the corresponding atom.

### How many neutrons are the ion iodine?

Solution. The atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 – 53 = 74).

What are the protons neutrons and electrons of iodine?

SolutionThe atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74).

How many protons and electrons are present in each ion I?

Iodine/Atomic number

What is the number of protons of iodine?

How do you find the protons neutrons and electrons?

To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number.
