Neutron star

Electromagnetic waves are a type of radiation that is produced from electrons (negatively charged particles) and x-rays is a type of electromagnetic wave. The shorter the wavelength of a wave, the more energy the wave emits. Gamma radiation has the shortest wavelength amongst all the other electromagnetic waves and has the most energy. It cannot be seen or felt and can pass through almost anything. X-rays have slightly longer wavelengths than Gamma rays and has the second most energy emission.…

multiple simulations about nuclear energy. (https://phet.colorado.edu/en/search?q=nuclear) Calculate the mass (in grams) of uranium 235 (U-235) in 1.26 X10⁵ kilograms of UO₂ U-235 undergoes fission when a neutron is added to the nucleus to release Kr-89 as one of the products and 3 neutrons. What is the missing isotope produced in this nuclear fission reaction? Write the complete nuclear fission reaction.…

Elements are made of a single type of atom, which cannot be broken down into anything smaller. Inside an atom are the subatomic particles protons (positively charged) and neutrons (neutral), and outside are the electrons (negatively charged) that orbit the atom in an electron cloud. When two or more atoms of an element or elements bond together, they form a compound. Depending on the type of elements, there are different kinds of bonds that could form. Ionic bonds form between the atoms of at…

2.5 – Nuclear Physics What was initially known about the model of the atom before Thomson and Rutherford conducted their experiments? The first model of the atom is thought to have come from two Greek philosophers - Democritus and Leucippus – in the fifth century BC. These two philosophers believed that everything was made up of matter, and that you could half a given portion of matter (and keep halving the product) and eventually be left with something that couldn’t be halved again: the atom.…

civilian prisoner of war for four years. Once he was finally free, he returned to England to work with Ernest Rutherford in Cavendish Laboratory at Cambridge. Together, they were an unstoppable duo, inventing a new, complex idea that was later named the neutron. In the beginning of the Twentieth Century the atom was imagined of two types of particles: protons and electrons. The problem with thinking in these terms was that the atomic mass measurements were not matching up with the atomic…

repulsion? It will produce an explosion or nothing will happen? Question 2 It is possible to create an artificial neutron start with the knowledge that humanity have nowadays atoms? (I do not really sure if this question can be considerate part of the course, but at the same time that I watch the podcast, I start to search about neutrons and I found this video in You Tube about the neutron starts, it is origin and it is density). Prompt #1: Does it matter that you can not really touch…

This reactor works by the reaction of the fissile material. The fissile material is normally uranium-235 but others can be used. Each reaction that occurs emits neutrons that can induce more reactions. In order to keep this exponential process from quickly getting out of hand, control rods are inserted into the reactor core that absorb neutrons without causing a fission reaction. By controlling these rods and inserting them into the area where the fission reaction is taking place, the reaction…

An atomic model is a proposed idea of what an arrangement of an atom thought to look like. Many physicists such as Dalton Billiard, J.J. Thomson, Ernest Rutherford, and Neil Bohr proposed these ideas and made models based on their own ideas. Out of these physicists, Ernest Rutherford’s planetary model is the most generally accepted atomic model. Ernest Rutherford is a New Zealand born son to a Scottish wheelwright and an English schoolteacher. He did well in school academically as a child and…

X-Ray and Neutron Imaging In physics, radiation is described as the transmission or emission of energy in the form of particles such as electrons, neutrons, protons and alpha particles or waves through a medium such as space, air or through a material. Gamma radiation (γ) and electromagnetic radiation, such as x-rays, radio waves heat and visible light are all examples of radiation. One of the main modern physics discoveries was that each unit of a wavelength of any form of wave radiation will…

The Quantum-Mechanical Model of the Atom Introduction: The theory of quantum mechanics explains the behavior of the particles, such as photons (particles of light) and electrons, in the atomic and subatomic realms. Since the electrons of an atom determine many of its chemical and physical properties, quantum mechanics is foundational to understanding chemistry. Quantum-Mechanical Model- a model that explains the strange behavior of electrons Electromagnetic Radiation- a type of energy…
