the iron core at light speed and finally bounce off the core and explode. (Stellar Death) During nuclear fission chain reactions take place. “A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats.” (Nuclear Chain Reactions) The two “types” of chain reactions, one is the controlled type, nuclear power, and the second is the uncontrolled chain…

saying that anything that has mass and can occupy space is called matter. Atoms are the main components that make up matters. Name the particles that are in different form in an atom; answer to this question is electrons, protons and neutrons. Where protons and neutrons are found in an atom? Answer: proton can be find in the nucleus, and electrons are located in the shells outside of the nucleus. Can someone in the class defines a molecule? Answer: A molecule is defined as the smallest part of a…

Paragraph 1 The structural evolution of FePO4 studied from a temperature range of 294K to 1073K by neutron powder diffraction. It is unique from α-quartz isotopes. It is different because it’s a cation is a transition metal. The structure dimensions and atomic coordinates in the α phase tend to increase by great amounts as the high-temperature β-phase rises and exhibit first order transition at 980K. The atomic structure dimensions of the α-phase FePO4 increased in a non-uniform pattern with…

beanium experiment was performed to display a greater understanding of isotopes of an element. Atoms that belong to the same element with the same number of protons but differ in numbers of neutrons are called isotopes. Since the atomic mass of a element includes the sum of the number of protons and neutrons in the nucleus of the element, It can be said that isotopes would have a different mass. Heavier isotopes tend to react more slowly than lighter isotopes of the same element. Using the…

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…

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.…

Fission is a reaction when the nucleus of an atom, gets a neutron, and then splits into two or more nuclei. This causes a release in significant amounts of energy as well as more neutrons. These neutrons then go on to split more nuclei and a chain reaction takes place. Fusion is basically the reverse process of fission. In this situation the nuclei collide instead and join together to form an atom larger than helium. Nuclear power plant use fission to produce very large amounts of energy. Enough…

The atomic number to my element is 11, the mass number is 23, the number of neutrons is 12, the protons are 11 and the electrons are also 11, the electron configuration of my element is 1s22s22p63s1. The person who discovered my element is Humphry Davy. He discovered sodium in 1807. Origin of sodium is derived from the English word ‘soda’. The appearance of sodium is soft metal that tarnishes within seconds of being exposed to the air. It also reacts vigorously with water. Used as a…

evolution of atomic models. In the beginning, Democritus viewed the atom as a tiny, solid, round sphere, that was unable to be cut. He created the first model of an atom, that essentially depicted it as a solid sphere, free of electrons, protons, or neutrons that looks similar to a billiard ball. Next came Dalton, he believed that every element has its own specific atom. He also shared the belief that atoms could not be spilt,…

as deuterium and tritium – basically, hydrogen with extra neutrons) fuse to form helium, and the mass defect is released as energy." To define nuclear fusion and fission more clearly, fusion is the process in which two or more nuclei combine which forms a newer, more stable element, with a higher atomic number. Nuclear fission, on the other hand, is the “splitting of a nucleus into smaller fragments, accompanied by the release of neutrons…” For example, uranium-235 and plutonium-239 are…
