How many protons and electrons are in an iodide ion?
How many protons and electrons are in an iodide ion?
53 protons
Iodine has 53 protons and 53 electrons (because it has no charge the number of protons equals the number of electrons).
Are protons and electrons equal in an ion?
Ions. Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.
What has 53 protons and 74 neutrons and 54 electrons?
Iodine
| Name | Iodine |

Can iodine have 54 electrons?
I (iodine) atoms (atomic number 53) have 53 protons and 53 electrons. 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.
Is iodine an atom or ion?
Density (near r.t. ) Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius.
What happens if protons and electrons are not equal?
When the number of electrons does not equal the number of protons, the atom is ionized. (The atom is then called an ion).
What are the two types of ion?
There are two types of ions :
- cations.
- anions.
What is the chemical symbol for iodine?
(I)
iodine (I), chemical element, a member of the halogen elements, or Group 17 (Group VIIa) of the periodic table.
What element has a 2+ charge when it has 54 electrons?
Xe has an atomic mass of 54 which means it has a 54 protons and 54 electrons. An element with charge of -2 have 2 additional electrons in it.
Why does iodine have no charge?
Likewise, potassium is located in group 1, which means it has 1 valence electron. On the other hand, iodine is located in group 17 (main group 7), which means it has 7 valence electrons. It is easier for iodine to gain an electron rather than to lose 7, so it will form an anion, or negatively charged ion, I− .
