World Nuclear Association, “Fusion powers the Sun and stars as hydrogen atoms fuse together to form helium, and matter is converted into energy… Hydrogen, heated to very high temperatures change from a gas to a plasma in which the negatively-charged electrons are separated from the positively-charged atomic nuclei or ions.” (“Fusion”). Nuclear Fusion is a highly-coveted ability because the process of atoms fusing together yields energy as a byproduct (“Fusion”). It is for this reason that scientist have

The main focus of the book All Quiet in the Western Front, the author illustrates his ideas of war through writing. Understanding the nature of warfare allows the reader to easily be able to know specific events in that time period. The story involves a young man Paul and his beliefs and observations throughout his experience in war. His knowledge of warfare will change from when he first joined and to the end of his journey. - Erich Maria Remarque's classic war novel, All Quiet on the Western Front

In Khaled Hosseini’s novel A Thousand Splendid Suns. Hosseini suggests that the factors outside of our control often significantly impact our potential to achieve a sense of happiness in life. This is first seen with Mariam in part 1 of the novel. Mariam’s wants to go to Jalil’s cinema with him, but when the time comes Jalil doesn’t show. She goes to his house to try to find him but he won’t see her, it is here she realizes that he may love her, but he is also greatly ashamed of her. This is something

Aldous Leonard Huxley was born on the 26th of July 1894 in Surrey, England. He was a writer and a philosopher, one of many accomplished minds in the family. His first years in school were spent at Hillside School in Malvern. There he was taught by his mother until her illness took charge. After that, he went on to attend Eton College. In 1908, at the age of 14, Huxley lost his mother. In 1911, Huxley himself became ill and lost, nearly entirely, his eyesight for about three years. At the beginning

Polar bears have a thick layer of fat called blubber which is about 11 cm thick. This also helps the bears to survive in the freezing conditions. Not only on land, but the thick layer of fur coat and blubber helps them as they spend a great amount of time swimming in the freezing waters of the Arctic. Blubber is a thick layer of fat that helps prevent sea mammals from getting too cold. Blubber in depth, is an extra digested food stored in the form of adipose tissue, which contains molecules called

This psychological assignment requires us to break a social norm. In my case, I decided to break an appearance social norm. I thought in something weird, but at the same time really funny. Therefore, I entered to my little walking closet and I took the most brilliant and extravagant high heels shoes that I found to wear them at a place when people usually used flip flops. 2- It was a hot and beautiful sunny morning when my boyfriend invited me to Sunny Isles Beach for a romantic walk. I dressed

the structure and arrangement of these atoms which determine the specific element, isotope and state. Each atoms is comprised protons, neutrons and electrons. The protons and the neutrons form the nucleus of the atom whilst the electrons orbit this nucleus in ‘shells’. The number of protons determine the element, the neutrons the isotope, and the electrons the charge. These atoms can be bonded together in one of three ways. Either metallic, ionic or covalent bonding. Metallic bonding only occurs in

The electrons in an atom occupy different energy levels. When all of the electrons are at the lowest possible energy level they are said to be in the ground state. Sometimes they can be promoted to a higher-energy electron shell. First, the electron can absorb a photon of just the right amount of energy to move it from one quantum shell to another. Second, when atoms are heated their electrons can gain energy from the heat. When an electron is in a higher-energy shell it is said to be in an

KCL is an ionic bond. This is because potassium (K) has a charge of +1 and chorine having a charge of -1. K gives one electron to chlorine, this makes it so both of them have a full valence shell. GeCl4 is a covalent bond, due to it being hard to separate its 4 valence electrons so Germanium shares its 4 valance electrons to Chlorine therefore making 5 full outer valence shells. BrCl is a covalent bond. Chlorine has a high electronegativity then bromine, and is a dipole-dipole which indicates to

Electron arrangement and trends in properties shielding the other electrons from the charge of the nucleus. As a result of this the other electrons are more strongly attracted to the nucleus, and the radius of the atom gets smaller. When an electron is added to an atom, forming an anion, the added electron repels other electrons, resulting in an increase in the size of the atom. In regards to the trend size of ionic radii is due to shielding of the outermost electrons by the inner-shell electrons

Electrons in Metals Fallyn Walker 14423422 An electron is a negatively charged, sub atomic particle. It is a fermion, a particle named after the Fermi-Dirac statistics, which describes the electrons behaviour . Bohr proposed that the electron could move from orbitals. This could explain the spectrum for hydrogen but failed for other elements. The electron has a half integer spin, which leads to intrinsic angular momentum, a feature that all fermions possess. Pauli’s Exclusion principle states that

essential to the formation of the world that we know today. The first type of bond involves the transfer of electrons from one atom to the next. This type of bond is known as Ionic bond and occurs between a metal and a nonmetal atom. These bonds are typically stronger than covalent bonds and involve atoms that have a large difference in their electronegativity or their ability to attract electrons. As a result of their strong bonds these molecules have a high boiling and melting point, a high polarity

9-B A chemical bond is form with the joining of two or more atoms (when two atoms are joined they form molecules and compounds.) Which are being held together by the attraction (force attraction) of atoms through sharing as well as exchanging electrons. Chemical bonds are found in molecules, crystals, or in solid metals. They also organized the atoms in order structures. But why are they important you may ask? They’re important because every material or substance in the world depends on chemical

loosely bound outer shell electron. The outer shell electron is knocked out of the outer shell and this causes the initial photon to lose some of its energy. This results in a recoil electron and a scattered photon. When the collision happens the scattered photon changes direction and the recoil electron (Compton Electron) is the electron that was once on the outer shell is sent on its own path. The scattered photon’s energy can be calculated by subtracting the recoiled electron from the initial photon’s

Photoelectric interaction is one of the main interactions in producing x-rays. This occurs when an inner shell electron is knocked out leaving a hole that needs to be filled. It will be filled by an outer shell electron which will be filled by an auger electron eventually. Photoelectric interaction doesn’t have as much scatter compared to the other interactions. This is due to the photons being almost completely absorbed by the patient as the photons pass through the body to hit the image receptor

1 The hydrogen atom has one electron which can occur in 3s, 3p and 3d and since it is one electron it experiences the same nuclear charge (full nuclear charge). The effective nuclear charge felt by more than one electron in an orbital is not the same. This is due to electrons have the same charges, thus repel each other and shield the nucleus. Helium has two electrons; hence electrons repel each other and shield the nucleus. Additionally, the 1s orbital is close to the nucleus as compared to 3s

they can do this by ionic bonding. Ionic bonding, atoms can gain or lose electrons to create positively or negatively charged atoms or groups of atoms called ions. Because of the attraction of opposite charged, plus (+) and mins (-), the ions are strongly attracted to one another. All the atoms over at the left-hand side of the periodic table from the zigzag line has just one or two electrons in their outer shells. All the atoms over at the left-hand side of the periodic table from the zigzag

protons more power to attract the electrons, the electronegativity decreases as you go down the groups because an extra shell is added every time this then causes an increase in nuclear charge due to more protons being added. This means that the nucleus is less able to attract electrons. Ionizing energy increases across a period because as the atoms radii is getting smaller the electrons get closer to the nucleus which creates a greater attraction for the electrons making it harder to remove them.

levels or shells which results in an increased distance from the nucleus which makes the atom larger. Since the energy level is increasing, the screening level also increases. This means that the electrons are blocked and are held more loosely than other electrons closer to the nucleus. This causes the atom to be larger. As atoms go down a family, they become more metallic. Since they are becoming more metallic, the atoms want to lose electrons and therefore don’t hold the electrons as tightly
