How many neutrons are in the nucleus of iodine 131?

78 neutrons
A less stable form of iodine also has 53 protons (this is what makes it behave chemically as iodine) but four extra neutrons, for a total atomic weight of 131 (53 protons and 78 neutrons). With “too many” neutrons in its nucleus, it is unstable and radioactive, with a half-life of eight days.

What is the nuclear notation of iodine?

For iodine-131, its mass number (A) is 131 , and its atomic number (Z) is 53 . Therefore, the nuclear notation for iodine-131 is 13153I .

What are the chemical properties of iodine 131?

Chemical properties: I-131 can change directly from a solid into a gas, skipping the liquid phase, in a process called sublimation. I-131 dissolves easily in water or alcohol. I-131 readily combines with other elements and does not stay in its pure form once released into the environment.

Is iodine-131 on the periodic table?

What type of radiation is iodine-131?

The most widely used iodine radioisotope, iodine-131, emits radiation in the form of medium energy gamma rays and beta particles, which disrupts molecules in cells and deposits energy in tissues, causing damage. Iodine-131 is used for diagnostic and therapeutic purposes in nuclear medicine and oncology.

Iodine/Atomic number

What is the composition of iodine?

Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. The molecular lattice contains discrete diatomic molecules, which are also present in the molten and the gaseous states. Above 700 °C (1,300 °F), dissociation into iodine atoms becomes appreciable.

How is iodine 131 produced?

Iodine-131 is an artificially produced fission by-product resulting from nuclear weapons, above-ground nuclear testing, and nuclear reactor operations. Iodine-131 is found in the gaseous and liquid waste streams of nuclear power plants, but is not released to the environment during normal reactor operations.

What type of radiation does iodine-131 emit?

What element does iodine-131 decay to?

Iodine-131 (131I, I-131) is an important radioisotope of iodine discovered by Glenn Seaborg and John Livingood in 1938 at the University of California, Berkeley. It has a radioactive decay half-life of about eight days….Iodine-131.

What is iodine I 131?

Iodine I 131 is a radioactive isotope of iodine with an atomic mass of 131, a half life of eight days, and potential antineoplastic activity. Selectively accumulating in the thyroid gland, iodine I 131 emits beta and gamma particles, thereby killing thyroid cells and decreasing thyroid hormone production.

What is the nuclear decay equation for iodine 131?

Its chemical form is a water-soluble salt. The nuclear decay equation is 131/53I → 131/54Xe + 0/-1E. The radioisotope’s mass number is 131 and its atomic symbol is I131. The radioisotope is a gamma and beta emitting isotope. Furthermore, the beta emission is the destructive component of the radioisotope.

What is the most stable form of iodine isotope?

Iodine-131 is the most stable form of iodine in an isotope. Iodine-131, when inside the human body, is absorbed by the thyroid, and is harmful in decay, when it decays into 131Xenon. Iodine-131 will also be airborne in the event of nuclear fallout.

Why are some isotopes of iodine used in nuclear imaging?

However, since the other 90% of radiation (beta radiation) causes tissue damage without contributing to any ability to see or “image” the isotope, other less-damaging radioisotopes of iodine such as iodine-123 (see isotopes of iodine) are preferred in situations when only nuclear imaging is required.
