Iodine is 127 and Magnesium is 24 so the difference is 103 Atomic Mass units.
Atomic mass of Iodine is 126.90447 ± 0.00003 u.
the atomic number is 53 and the atomic mass is 126.9 so you would round it up to 127
The Atomic Mass of Magnesium is 24, the RAM (relative atomic mass) is 24.305.
Iodine is a metal element. Atomic mass of it is 127.
Iodine is a non meta element. Atomic mass of it is 127.6.
Atomic mass of Iodine is 126.90447 ± 0.00003 u.
