Carbon 14

Radioactive element is an unstable nucleus spontaneously emits particles and energy in a process known as radioactive decay. Alternatively, it depends on how it might have been used, someone people use it for positive and others for negative

The pioneering work of Becquerel in 1896 (the discovery of uranium), and the Curies (who subsequently discovered radium and polonium and the energy and heat given off by these new elements which they called radioactivity) led to the remarkable work of Ernest Rutherford. He was a physicist, whose experiments showed that some heavier elements spontaneously changed or decayed into lighter elements (unstable 'parent' elements giving off protons and neutrons to form a 'daughter' element) through the process of radioactivity. He discovered that radioactive materials decay at a very predictable rate, and that lead was the final decay product of uranium. Using Rutherford's ideas, Bertram Boltwood pioneered a method of radiometric dating in 1907. He hypothesized that since he knew how long it takes uranium to break down, he could measure the proportions of lead in uranium ores, and use his calculations to date how long those ores had existed,

Iodine-131’s atomic structure has 5 energy levels in total. The first energy level has 2 electrons, second energy level has 8 electrons, third energy level has 18 electrons, fourth energy level has 18 electrons and finally the fifth energy level has 7 electrons. The radioisotope has a half-life of 8.0 days and every half-life in the radioactive Iodine is reduced by 50%, however, the other 50% does not become part of Iodine-131 because it becomes stable. The radioisotope has 53 protons and 78 neutrons in total. It has a blackish colour to it. 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. This is supported by the fact that Beta emission is an electron that is ejected from the nucleus which is very ionizing. The aspect also makes beta electrons very destructive to thyroid tissue as it concentrates the iodine 200x more than any tissue in order to make thyroxine which is an endocrine hormone to regulate at the rate of metabolic processes.

The A simple definition of the word radioactiveis to have or develope a strong and dangerous form of energy. This could also be named radiation. A radioactive substance incvolves a very harmful form of energy that is developed betwen nuclear reactions. In the book "The Radioactive Boyscout" by ken Silversteint, there are several examples of radioactive substances being produced. The main character in the book is very as the title says "radioactive"

Carbon has three naturally occurring isotopes, with 12C and 13C being stable, while 14C is a radioisotope, decaying with a half-life of about 5,730 years.

Observed spontaneous disintegration of radioactive elements into variants he called "isotopes" or totally new elements, discovered "half-life", made initial calculations on energy released during decay.

The sixth element on the Periodic Table is Carbon. Carbon’s name originated from the Latin word “carbo.”This in Latin actually means charcoal, which is the first basic form Carbon was used for. (“History of Carbon”)There are many compounds that Carbon is found in our world. Carbon was first found in prehistoric times and therefore there is no true discoverer. In these times the Egyptians and Sumerians used charcoal, a form of carbon, to reduce metals to make bronze. (“History of Carbon”) Later, charcoal was used for medicinal uses by the Egyptians. They used charcoal as a way to absorb odors from wounds that were infected and from inside the digestive system. This started the use of charcoal more and more for medical purposes.

The chemical element of atomic number 15 obtains 30.974 atomic mass units. Phosphorus has 23 isotopes. Because this element has 3 energy levels, it is located in period 3. Phosphorus is within the Nitrogen Family. Other members in this family are Nitrogen and Arsenic. These are all in the Nitrogen Family because they all have 5 valence electrons.

Radioactive decay is the spontaneous breakdown of an atomic nucleus resulting in the release of energy and matter from the nucleus. Remember that a radioisotope has unstable nuclei that does not have enough binding energy to hold the nucleus together. Radioisotopes would like to be stable isotopes so they are constantly changing to try and stabilize. In the process, they will release energy and matter from their nucleus and often transform into a new element. This process, called transmutation, is the change of one element into another as a result of changes within the nucleus. The radioactive decay and transmutation process will continue until a new element is formed that has a stable nucleus and is not radioactive. Transmutation can occur

Explain the decay process that applies to the use of this radioisotope. Include a labelled diagram (a paragraph)

Silicon is the 14th number in the periodic table. It has 14 protons ,electrons and 12 neutrons. It is in period 3 and also has 3 energy levels. The number of electrons in each level go : 2, 8, 4. Silicon has 24 isotopes and the most stable isotopes are 29Si and 30Si. The atomic mass is 28.085 but when its rounded its 28 AMU. Silicon is highly reactive with other elements

Cobalt decays to form Nickel-60. As it decomposes, it releases gamma radiation. Beta particles also occur when Carbon-60 decays (4). The nuclear

A major characteristic of radioactive material is that it decays from one element to another through particle and gamma decay. Essentially, all radioactive materials are byproducts of previously decayed elements. In order to utilize the radioisotopes of their choice, providers must artificially employ forms of specific radionuclide formation. This process is induced in a variety of ways, namely, production in a particle accelerator or creation in a nuclear reactor.

First, radiocarbon looks at the subatomic particles that constantly bombard the earth and produce high-energy neutrons. When the neutrons collide with the nitrogen atoms present in the earth 's atmosphere, they produce atoms of Carbon 14. These atoms

The term radioactivity was actually named by Marie Curie, who together with her husband Pierre, began investigating the phenomenon recently discovered by Becquerel. The Curies extracted uranium from ore and to their surprise, found that the leftover ore showed more activity than the pure uranium. They concluded that the ore contained other radioactive elements. This led to the discoveries of the elements polonium and radium. It took four more years of processing tons of ore to isolate enough of each element to determine their chemical properties.
