Helium

It is mostly made up of hydrogen and helium. The Sun makes up 99.98% of the mass in the Solar System. The Sun is also made up of multiple of layers like Earth. The inner layers consist of the Core, Radiation Zone and the Convection Zone. The Core is 150 times more dense than water and is measured…

material is cold enough for icy compounds to remain solid. The ices that created many of the planets were more common than the metals and materials that formed the inner planets, letting them grow big enough to take large atmospheres of hydrogen and helium to form something. Leftover space trash that never becomes planets in regions such as the Asteroid Belt, and Kuiper…

The Physics of PET Scans All elements are composed of atoms, which are composed of small particles called protons, neutrons, and electrons. The nucleus of an atom is made of a tightly packed collection of protons and neutrons. You would think that with positively charged protons being packed so closely together the nucleus would fall apart, however this is not the case. There is an attractive force called the “nuclear force” which is able to overcome the repulsive force of the adjacent…

Neptune is one of the four large planets in our Solar System known as Gas Giants. It is the eighth planet in order from the Sun, and was seen through a telescope for the first time on the 23rd of September 1846. Keeping to the traditional naming system used for all the previous planets, Neptune was given its name based on the Roman god of the sea, in reference to Greek and Roman mythology. General Information: Neptune has a vivid blue colouration to its layer of cloud cover. Higher…

Chemistry Honors Mrs. Moreno Period 5 INTERPRETING THE PERIODIC TABLE Partner’s name: Faranak Hajikhan, Pablo Moncada, Albina Contreras and Karla Santos Title: Interpreting the Periodic Table Date: 12-18-14 Subject: Honors Chemistry / Period 5 Introduction: The periodic table is a table of the chemical elements in which the elements are arranged by order of a atomic number. The periodic table also has a special name for its vertical columns. Each…

The doctor advised her that due to her condition, if she chose to continue to fuse silicon into iron- to nurture her iron baby- she would get too hot and she could potentially collapse. Back in the day, Arcturus was able to combine hydrogen into helium particles in a blink of an eye, but inevitably, her energy to sustain living has dissipated all of her strength after she was with child. Arcturus did not listen. Within a flash, Arcturus came face to face with destruction. An explosion of…

Introduction: With the constant rise for global energy, there is a huge demand for environmentally clean and cheap energy sources. Now, for many years power generated by nuclear power plants has been a reliable source for energy but the current amount of uranium, which is the fuel will satisfy the energy requirements for the next 200 years. Also, the nuclear reactors are not very efficient as not all of the uranium mined is being used to generate power. In this essay, I will discuss an alternate…

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…

Alchemists used to obsess over chrysopoeia, the transmutation of regular metals, such as copper, into gold. However, they were not aware at the time that copper and gold were two different atomic elements and instead believed them to be compounds. Thinking these metals could be changed chemically or physically in labs, alchemists pursued this dream to no advantage. Although it is not possible to change ordinary metals to gold through chemical reactions, physical reactions, radioactive decay, or…

Medical arguments against assisted dying include the possibility of misdiagnosis, the potential availability of new treatments, and conflict with the physician’s role as a healer. Farr Curlin’s study shows 69 percent of U.S. physicians are against physician assisted suicide (Curlin). In an article “Why Physicians Should Oppose Assisted Suicide” Tony Yang says “…with physician-assisted-suicide, the physician is to disregard what is perhaps the most universal moral injunction – do not kill…” Yang…
