Iodine Isotopes are the atoms that have in their nucleus an atomic number corresponding to the chemical behavior of that element. Since isotopes have the same number of protons, they all have identical chemical behavior. But, however, since their neutron numbers are different the isotopes of the same element may have different radioactivity. An isotope that is radioactive is called a radioisotope like iodine, which is important in our health. In radioactivity, the nucleus of an unstable isotope or element breaks down by itself and gives off rays and particles; the ratio of neutrons to protons for stable isotopes increases for heavier elements and the ratio for stability for the most stable isotopes. Iodine is one of the earliest elements whose radioisotopes were used in nuclear medicine. The most common, stable form of iodine has an atomic number of 53 and an atomic weight of 127, this is because you have 53 protons plus 74 neutrons. These numbers mean that the nucleus is stable and not radioactive. However, a lesser stable form of iodine has 53 protons but only four extra neutrons, for a total atomic weight of 131. With too many neutrons in its nucleus, iodine is unstable and radioactive with a half life of up to eight days. Because of its radioactivity, Iodine 131 can be detected in the body, particularly in the thyroid gland. Iodine can be used as a form of a solution in medicine as a germicide as well. In producing purple dye, its radioactive isotopes can also be used in medical diagnosis; for example it can be used to treat thyroid cancer and act as a tracer in the body to determine how well the thyroid is functioning. As a matter of fact, we humans need about 140mg of iodine a day. Foods such as fish, sea vegetables, and other foods of marine origin, are your dietary iodine in which is usually taken in. Iodine is also added to salt to make sure that people around the world get enough of their dietary iodine, called Iodized Salt. Regardless of the

    Many advanced high school and college chemistry students perform an experiment known as the "iodine-clock" reaction, in which hydrogen peroxide reacts with iodide to form iodine, and the iodine subsequently reacts with thiosulfate ion until the thiosulfate has been consumed. At that point, the reaction solutions turn blue in the presence of starch. The experiment helps students understand the fundamentals of chemical kinetics --- the speeds at which reactions take place. 1. Activation Energy…

    INTRODUCTION Iodine deficiency disorders are still very much prevalent in the world today. Two billion people, estimated by the WHO, still lack a sufficient level of iodine in their diets which leads to a range of disorders known as iodine deficiency disorders (IDD). So what is iodine? Iodine is an essential micronutrient in the diet which is used by the thyroid gland (located in the throat) to produce thyroid hormones which help control the body’s metabolism. The two most important thyroid…

    Iodine Test for Starch Introduction and Hypothesis: In this experiment, we used iodine to test for starch in certain solutions. Iodine separates starch from polysaccharides, monosaccharides, and disaccharides. Starch is a curled polymer of glucose and iodine interacts with molecules, which changes the color of the molecules to a kind of black color. Iodine does not respond with carbohydrates that are not curled or coiled, thus the color stays yellowish brown. A black color result means that starch…

    Iodine: Thyroid Gland

    Iodine is an element that is critical for normal function of the thyroid gland, which is a key regulator of the body's basic metabolic rate. Iodine is a micronutrient, meaning we require only small amounts of it. For example, adults need about 150 micrograms of iodine in the form of iodide ion per day. However, an insufficient supply of iodide via diet and drinking water causes the non-cancerous enlargement of the thyroid gland known as goiter. Prolonged lack of iodide can lead to loss of thyroid…
