One of the main experiments Rutherford is known for is his Gold foil experiment. He devised a way to prove that radioactivity in particles exists in at least two forms. In the experiment tiny alpha particles were shot at a sheet of foil coated in ZnS which resulted in a small percentage went through the sheet and the rest were blocked/deflected. The percentage of particles that were able to go through the foil are now named 'Alpha Particles' and the ones that were blocked are called 'Beta…

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…

was an important step in creating the nuclear model for all atoms. Most importantly, Rutherford’s Nuclear Atomic Model helped Bohr create his Planetary Model, which is close to the model that we use to describe atoms today, and the discovery of the neutron. From his important discoveries, Rutherford was dubbed the name “The Father of Nuclear Physics” and I would like to know why he was first interested in atoms and atomic structure in the first place, and what led him to using the gold foil…

Beta particles are caused when a neutron in an unstable atom splits apart to form a proton/positron and an electron, the electron is referred to as a beta negative particle and the positron is refered to as a beta positive particle. The electron is shot from the nucleus and out of the atom…

Radioisotopes are atoms that consist of unstable combination of neutrons and protons. All elements which have their atomic numbers greater than 83 are radioisotopes and have unstable, radioactive nuclei. They have at least one stable isotope and one unstable isotope. In order to gain stable conformation the nucleus of the atoms loses a neutron due to which radiation energy is given off and the atom is said to be in radioactive state. They are also called as radionuclides because they have more…

distance from the source and if thickness of the material effects how much radiation gets through. Introduction-One thing to know about this experiment is Isotopes.Isotopes of an element are different versions with same number of neutrons but different number of neutrons. Also these isotopes can be unstable which means they decay overtime releasing radiation. Radiation is the what we are going to look at while doing the experiment. List of materials/equipment and Safety Precautions -Geiger…

symmetry being tetrahedral in shape. On the other hand, the space group for β-FePO4 is P6422, with the lattice symmetry being hexagonal in shape. In this writing assignment, FePO4 is studied at varying temperature ranging from 294K to 1073K by neutron powder diffraction. At a relatively low temperature, it adopts the structure of the α-quartz. However, at high pressures, it changes and it can be observed that it becomes a denser octahedral structure due to a phase change occurring, which…

In the paper, FePO4 was studied in through neutron powder diffraction across a wide range of temperatures, and was found to have 2 states in general, the α (alpha) phase and β ( beta ) phase. The alpha phase exhibits a tetrahedral structure, which is similar to alpha quartz, and this occurs during generally low temperatures. In the case of this paper, the temperatures experimented on were between 294K and 1073K. The beta phase, however, is denser and exhibits a octahedral structure. The…

The element I selected for the Element Research Project is Osmium. Osmium’s chemical symbol is Os. Osmium’s atomic mass is 190 amu. Osmium’s atomic number is 76, it has 76 protons and 76 electrons. Osmium also has 114 neutrons. Osmium belongs to the transition metal group in the middle of the periodic table. Osmium’s Bohr model with electric configuration has two electrons in the first shell, eight in the second shell, eighteen is the third shell, thirty two in the fourth shell, fourteen in the…

I am researching the element, boron. The symbol of boron is a just a capital B. The atomic number of boron is 5. Boron’s mass is 10.811 grams. Boron has 5 protons, 6 neutrons, and 5 electrons. The Periodic Table lists elements in numerical order from the smallest atomic number to the largest atomic number. That is why boron is the 5th element on the Periodic Table. It comes after beryllium and before carbon. Boron was discovered on June 30th in 1808. It was discovered by French chemists,…
