IODINE

• The number of protons in a neutral atom is 53.
• The number of electrons in a neutral atom is 53
• Number of neutrons in a neutral atom are 74.

IODINE

• The state of matter is Solid.
• The number of isotopes that form are 37.
• Number of neutrons in each isotope is 74
• Ions that for are I-
• The reason ion forms because iodide ions loose electrons and form iodine.
