Neutron star

Eureka! Do you remember that pleasant feeling when a brilliant idea flashed into your head? Over 2000 years ago in ancient Greece, a physicist Archimedes was trying to solve a problem of physics. One day, while taking a bath, he suddenly got an inspiration, and discovered a breakthrough principle. He got so excited about this discovery that he leapt out the bathtub, ran through the streets without his clothes, and cried out, "Eureka!”: in English, “I’ve found it!”, the word to express our…

The purpose of this paper is to find out what material is the gold crown ring made out of. What is interesting about this topic is that there is a lot of ways to study the gold crown ring. For example, you can test the mass, volume, and density of the ring. In the periodic table Au is the symbol for Gold, it’s atomic number is 79. The Properties of Matter are Mass, Weight, Volume, and Length. Each property has its own way of working with different types of things. It is believed that the…

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…

Atoms What is so tiny that you cannot see with the naked eye, but despite their size are extremely important? Atoms are! Atoms are so important. Atoms are the building blocks of the world. They are in everything. Millions of little atoms join together to create the world and everything in it. They can also be used for other purposes not naturally, such as an atomic bomb. Atoms are critical to our survival at a whole. The history of the atom dates back to ancient times. Ancient…

Radon is a colorless chemically-unreactive inert gas. You cannot see it, smell it or taste it. The atomic radius is 1.34 angstroms and it is the heaviest known gas. Radon is nine times denser than air. Because it is a single atom gas it easily penetrates many common materials like paper, low density plastic, most paints, and building materials like gypsum board, concrete block, wood paneling, and most insulations. Radon was discovered by Ernest Rutherford and Robert B. Owens in 1899.…

One of the most important scientific discoveries is that of the atom. The Atom is the smallest unit of matter. “Atoms are mostly empty space” (OI/ https://www.thoughtco.com/interesting-facts-about-atoms-603817). It makes up all the four elements. “There are over 100 different kinds of atoms ”(OI/https://www.thoughtco.com/interesting-facts-about-atoms-603817).Over time the theories about the atom have changed a lot, moving from simple to complex. Before 1900, scientists made several…

Contribution to the modern atomic theory the modern atomic theory states that most of an atom is empty space, an atom consists of a small, dense nucleus surrounded by electrons, atoms contain subatomic particles, and the nucleus contains only protons and neutrons. Rutherford's ideas are present all throughout today's atomic model. The scientist that told us “Most of an atom is empty space” was Rutherford. He was also the one who suggested that electrons move in clouds. Though it being somewhat…

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,…

“Steel plates are commonly attached to each other with rivets, which are slipped into holes in the plates and rounded over with hammers. The hotness of the rivets makes them easier to round over, but their hotness has another important advantage in providing a tight fit. What is it? Explain why.” This relates to one of the characteristics of heat, in that heated objects expand, then contract when the temperature decreases, since the molecules move faster in heat and slow in the cold. The hot…

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…
