Radioactive decay

Radioactive decay occurs when the nucleus discharges an abundance of energy, in the type of waves, causing nuclear instability which can occur naturally or spontaneously. Alpha (α), beta (β), and gamma particles (γ) are the most known types of radioactive decay despite the fact that there are some more. Alpha decay, α, composes of two neutrons and two protons making alpha particles similar the nucleus of helium. Large components, for example, uranium, radium, and thorium have a greater number of neutrons than they have protons which aids alpha decay to happen. At the point when another atom is made the mass number decreases by four and its atomic number by two after the core discharges an alpha particle which contains two less protons and neutrons. Right when another atom is made the mass number declines by four and its nuclear number by two after the center releases an alpha molecule which contains two less protons and neutrons. Unlike alpha decay, beta decay comes in two forms β+ and β-. The strategy in…

Task 1: radioactive decay is a nuclei of some isotopes which are unstable. If a radioactive isotope decays the it will change and become a different atom with different number of protons. Radioactive decays also are a process which has an unstable atomic nucleus and which causes it to lose energy this because of radiation, for example there three main types of radioactive decay alpha, beta, and gamma particle. If a material has unstable nuclei it would be considered as radioactive. If an atom…

Half-life Carbon dating is used to find the age of fossils, the earth, and rocks. 14C is an unstable isotope that causes radioactive decay. Because 14C causes radioactive decay, it is used in finding the age of organic matter, or the process of Carbon dating. Radioactive decay occurs when one element changes into another element as it decays. As 14C decays, it turns into 14N, an isotope of Nitrogen. Using the original amount of carbon in the organic material, and the half-life of carbon, 5,730…

There are several areas in the natural world where the process of exponential decay arises from random processes. Whenever a material decays at a rate in proportion to its amount, this material represents the process of exponential decay. Exponential decay can be described using the mathematical model y=a×e^(-bx). A prominent example of naturally occurring random exponential decay is the process of radioactive decay. Some isotopes of nature are considered radioactive due to a specific…

Collectively the pennies represent a radioactive sample, and each penny is an atom. Because each penny has a 50% chance of decaying it can represent a radioactive atom. When the atoms are grouped together it becomes a sample of a radioactive element. For the simulation to work one has to assume that a coin toss has a 50% chance of landing on heads and a 50% chance of landing on tails. If this is not true then the trial will not be a true half-life because more or less than half of the atoms…

The medical use of radioactive isotopes for cancer treatment can be classified as radiation therapy. The radiation that specific isotopes give off are utilized for effecting cancer cells. First of all, what is radiation? Radiation is energy that is carried by waves of streams of particles. The energy from radiation damages the genes (DNA) in the cancer cells. The damage done to the cells prevent them from growing and dividing, and often cause them to die off. Nearby normal and healthy cells can…

Iridium-192 is a radioactive isotope that’s used daily in a series of world changing ways. It’s a synthetically produced metal, made as a by-product of nickel and copper, and the Iridium-containing ores are found in the U.S.A, Alaska, South Africa and Australia. Used both in the medical and industrial world, this radioisotope is underappreciated for its benefits to society. Though there are some risks, the reward undeniably outweighs them. Iridium-192 has a half-life of approximately 73 days,…

Once a living thing dies, the carbon dating process begins. As long as an organism is alive it will continue to take in 14C or radio carbon; however, when it dies, it will stop. Since 14C is radioactive (decays into 14N), the amount of 14C in a dead organism gets less and less over time. Therefore, part of the dating process involves measuring the amount of 14C that remains after some has decayed. Scientists now use a device called AMS (don't know what it stands for) to figure out the ratio of…

Natalie Caparelli Mrs.Stanton October 5, 2015 Is Nuclear Chemistry Worth The Risk? Pros and Cons of Nuclear Chemistry in Medicine Nuclear chemistry, along with its advantages, has many cons such as extended decay periods, emission of radioactive particles into the atmosphere, and negative side effects from its many medical uses. Radioactive particles vary in strength, alpha particles, for example, are able to pass through sheet of paper. On the other hand, gamma rays are about to pass through…

In 1896, Henri Becquerel expanded the field of chemistry so nuclear changes would be included, after he discovered that uranium could disembogue radiation. Not very long after his discovery, Marie Curie began studying in the field of radiation, and completed most of the pioneering work on nuclear changes. Marie Curie discovered that radiation was related to the amount of radioactive element that is present, she also discovered that radiation was a property of atoms. Curie was the first woman to…
