Iodine is a non meta element. Atomic mass of it is 127.6.
They show that the periodic table isn't arranged on the basis of increasing atomic mass because iodine has a mass lesser than tellurium. Iodine has a mass of 126.90 and tellurium has a mass of 127.60.
The atomic number is the same as the number of protons in the nucleus of the particle. Therefore, every atom, ion, and isotope of iodine has an atomic number of 53 (regardless of its mass number).
this happens with argon and potassium, and also with cobalt nickel. fun stuff.
The Atomic number of iodine is 53.
Iodine is a halogen. Single atom has 53 protons.
