Neutron activation analysis

a chart known as the periodic table, one such element is Germanium. In fact, Germanium has a symbol known as Ge. A symbol is a shorter way to represent the element. All elements have a symbol, atomic mass, atomic number, and a number of protons, neutrons, and electrons. Germanium’s atomic mass is 72.64, this is the amount of mass in each atom that’s in Germanium. The atomic number for Germanium is 32, which represents where the element is placed on the periodic table and the amount of…

The Periodic table is a table that organizes the different known elements, and Neon is one of those elements. Neon is an element that is a non-metal and also a noble gas. The start of the element, Neon, was when a Scottish chemist named William Ramsay discovered Neon, Krypton, and Argon, which are all noble gasses ("Periodic Table of Elements: Los Alamos National Laboratory." Periodic Table of Elements: Los Alamos National Laboratory). For this achievement, William Ramsay won the Nobel Prize in…

A nuclear power plant uses Nuclear Fission to create energy. Nuclear fission occurs when a neutron passes by a heavy nucleus such as Uranium-235, the nucleus may capture the neutron which may or may not cause nuclear fission. If the reactor used is U-235 when a neutron is captured the energy is spread out through the 236 nucleons (both protons and neutrons) that are currently present in the nucleus. This nucleus is likely to break up into two fragments due to its instability. These fragments are…

SLS43-14/7-8 Pre-Lab Questions: 1) An isotope is an atom with a different atomic weight due to changes in the number of neutrons in the nucleus. Some examples of isotopes are Protium, Deuterium, and Tritium, which are all Hydrogen atoms. Instead of the zero neutrons Hydrogen has in its Protium form, Deuterium and Tritium have two and three neutrons respectively. This change in neutron number and therefore atomic weight classify these atoms as isotopes of the element Hydrogen. An ion is an atom…

Carbon-12 represents an ion and an isotope. Carbon-12 has six protons and six neutrons in its nucleus, as shown on the diagram. Outside of the nucleus, this atom has five electrons. The protons are shown in the color orange, neutrons are in the color blue, and electrons in the color teal. The scientific principle subatomic particles says they are smaller than the atom itself, meaning protons with a positive charge, neutrons with a neutral charge, and electrons with a negative charge are all…

drastically changed over time. What we know as an atom today is composed of many subatomic particles. There is a positively charged center in an atom called the nucleus, which contains protons and neutrons (Doc. 3). The number of protons determine what element the atom is, and the number of neutrons influences the atom’s mass. There are also negatively charged particles, called electrons, to counteract the positive charge of the nucleus. These electrons fly around the atom’s empty space, which…

Chapter 11, “The Chemical Elements”, was of great interest to me. “Chemistry is the study is the study of the composition and structure of matter (anything that has mass) and the chemical reactions by which substances are changed into other substances (James T. Shipman 285).” In this summary paper, I will discuss some of the highlights of the chapter. The way I see it, God is the original/first chemist. He took His own creations (the elements in our Periodic Table) to make provisions for…

Atoms are made up of particles called neutrons, protons and electrons. Electrons have a negative electrical charge, protons have a positive electrical charge, and neutrons have no electrical charge. The neutrons and protons group together in the middle part of the atom, which is called the nucleus. An individual atom atoms will have at least as many neutrons as protons and it will have the same amount of electrons and protons. Atoms have a large amount of energy which holds their nuclei together…

1.Please explain how medical magnetic resonance imaging (MRI) exploits the magnetic properties of the nucleus. MRI exploits the process known as nuclear magnetic resonance (NMR). In fact the technique used to be called simply NMR or NMR imaging, but the “nuclear” was dropped because of the connotation of radiation hazards from unstable nuclear sources, although there is no logical rationale for such fear. In NMR, a sample of material is placed in a strong magnetic field. The nuclei in the sample…

Elements above the atomic number 95 are produced in a particle accelerator by accelerating a small charged nuclei (such as Helium, Boron or Carbon) in a particle accelerator to combine with a heavy nucleus (often of a previously made transuranic element) target. The transuranic elements have short half-lives as the atomic number increases. The smaller nuclei combines within the target nucleus, creating a new unstable nuclide or radioactive isotope. The high speeds are required to overcome the…
