What is the atomic symbol for iodine-127?
Iodine-127 atom | HI – PubChem.
How many neutrons does iodine-127 have?
Iodine atoms normally have fifty-three protons and seventy-four neutrons giving an atomic weight of 127.
How many electrons does iodine-127 have?
54
Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74). Since the iodine is added as a 1− anion, the number of electrons is 54 [53 – (1–) = 54].
What is the mass number for iodine-127?
126.904468
CHEBI:52631 – iodine-127 atom. The stable isotope of iodine with relative atomic mass 126.904468, 100 atom percent natural abundance and nuclear spin 5/2.
What is the use of iodine-127?
Stable iodine-127 is used as a dietary supplement for thyroid deficiencies. In addition, iodine-131, iodine-125, and iodine-123 are used for imaging, and iodine-131 is used for therapy for treatment of various thyroid conditions.
Is iodine-127 and iodine-131 isotopes?
…isotope of iodine is stable iodine-127. An exceptionally useful radioactive isotope is iodine-131, which has a half-life of eight days. It is employed in medicine to monitor thyroid gland functioning, to treat goitre and thyroid cancer, and to locate tumours of the brain and of the liver.
What atom has a mass number of 127?
Tin, isotope of mass 127.
How many protons electrons and neutrons respectively does 127 I have?
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).
How many protons electrons and neutrons does 127 have?
