Isotope

“super weapon” – possibly using nuclear/atomic energy. Already, German scientists had discovered the technique of splitting uranium atoms – called nuclear fission – by the bombardment of these atoms using neutrons, splitting them apart into rare isotopes, the most important of which, and the one that would help produce nuclear energy being U-235. This extremely rare substance and another, the newly found element plutonium (also capable of massive nuclear reactions) were to be the foundations…

Carbon-12 is stable and makes up 99% of all Carbon on Earth, therefore it is the most abundant isotope. Carbon-13 is also stable and the heaviest of the three isotopes. The last and final isotope is Carbon-14 radioactive, known as unstable with a half life. During the first half it is blue but over time in turns into Nitrogen-14. It also is used for Carbon dating. Carbon's atomic number is six…

metal. Thankfully, there are numerous minerals in Magnesium. Two of the most common minerals are dolomite and magnesite. These minerals and the element itself can be discovered in sea water. Saying this, come and see what its origin of name is, its isotopes, five main characteristics, and more! First off, the origin name of a magnesium is the greek word, magnesia. A fun fact about the element is that if you add water to a magnesium fire produces hydrogen…

Radioiodine production Radioiodine is defined as a radioactive isotope of the chemical element Iodine. Although there are at least 37 different Iodine radioisotopes, only four of them are used as tracers or therapeutic agents in medicine; these are 123-I, 124-I, 125-I, and 131-I, with the latter being the most common in clinical practice. Essentially all industrial production of radioiodine isotopes involves four aforementioned radionuclides. History of radioiodine production and usage The…

An isotope is an atom containing different numbers of neutrons, differing in atomic mass. Basically an atom with a different atomic mass. What’s special about radioactive isotopes is that a radioactive isotope has a nucleus that decays spontaneously giving off particles and energy. 6. Radioactive tracers are used in science to label certain chemical substances, so metabolic processes can be followed and substances can be located in an organism. Radioactive tracers are important diagnostic…

Atoms, ions, and isotopes are everything you eat, breathe and see. They are everywhere and everything is made up of them. The first person that aided in the discovery of the atom was Democritus in 400 BC. He is the one that named the atom. The word atom comes from the Greek word atomos which means indivisible. Aristotle which was another flossier in at that same time disagreed with him. He believed that matter could be divide infinitely without changing its properties. At that time more people…

The largest dinosaurs to walk the Earth may have embarked on seasonal migrations that covered hundreds of kilometres when local watering holes dried up and food became scarce. Evidence that giant sauropods set off on epic journeys came to light when scientists examined fossilised teeth recovered from the remains of beasts unearthed in Wyoming and Utah in the US. The analysis of 32 teeth belonging to two species of Camarasaurus, among the most common sauropods found in North America, suggests…

Even though utilizing nuclear fission as a power source does have its respectable pros, the cons seem to overwhelm the pros. Setting up nuclear power plants is very expensive and the majority of nuclear power plants’ fuel relies on a very meager source. The other cons include and are not limited to: mining for the meager source poses a health risk to the people mining and not mining and if not dealt with properly, the radioactive materials used in a nuclear power plant can severely harm the…

Types of Spectroscopy used in Organic Chemistry 1.1 Introduction Spectroscopy is the study of the interaction between matter and light (electromagnetic radiation) (Crouch & Skoog, 2007). It is often phrased as the light of knowledge (Reusch, 2013). In the past, spectroscopy started by the study of visible light dispersed according to its wavelength by a prism (Anon., n.d.). Now, with the knowledge of light having both wave-like and particle-like characteristics, with given frequency or…

primrose species, Primula verticillata and Primula floribunda. Sedimentary rocks We do not know the actual, or absolute, age of the fossil. We can only infer. Radiometric dating is a process in which a radioactive “parent” isotope decays into a “daughter” isotope. This decay is expressed by the half-life, which is the time that is required for 50% of the parent…
