Name University Course Instructor Date Quantum Physics Exam 3 Problem1. Hydrogen Essentials PART A: Make a plot of the energy levels of the hydrogen atom. Plot the energy values En in the vertical direction for n = 1, 2,3,4,5. Plot the orbital angular momentum quantum number in the horizontal direction for l = 0,1,2,3,4. For each n, show every allowed value of l. Label every energy level spectroscopically (1s, 2s, 2p, ...).
In the periodic table lithium’s atomic number is 3. The atomic number describes the number of protons in the nucleus and the number of electrons in the atom when it is not ionized. (An ion is an atom where the amount of protons and electrons is not equal.) Lithium has 3 protons; therefore it must have 3 electrons when it is not ionized. The protons and neutrons together form the nucleus.
The biological response is different among tissues and organs that receive radiation. It does not depend only on total receives doses but also frequently exposed to radiation. For example, testis would not be easily damaged with only single dose but frequently exposed to the same doses will be damaged but ovary will damage if exposed to single dose. Radiation to uterus will give effect and damage the tissues. Woman that exposed to radiation will have implication of infertility and failure to have a baby.
Qualitative Analysis Testing on ions- Cations and anions can be identified in various different ways and on different levels. Many Qualitive analysis tests can be done to identify cations and anions through change of temperature and chemical reactions. The ‘Flame test’ is designed to identify a cation in a compound solution through changes of temperature, the cation can be identified by the color of the flame it produces. On the other hand, the ‘Precipitate test’ is designed to identify the anion in a compound solution this is done through the type of simple chemical reaction it produces. Cations are positively charged ions, there is only one type of cation.
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.
There are different kinds of radiation such as ionizing radiation, like x-ray’s, and non-ionizing radiation, like ultraviolet rays. Welding lets off ultraviolet rays that can damage a welder’s eyes and burn his skin. To avoid the effects of radiation when welding, a welder should wear a suede jacket that protects his skin and wear a welding shield with a lens to protect his eye from the ultraviolet rays. Electrical hazards are another major concern in welding. The hazards of electrical injury are very severe and can be caused by cutting or welding.
Gamma rays of this system are ionizing radiation that causes changes in body’s molecules. Too much exposure to ionizing radiation can damage the tissues. Children, young women and fetus are more sensitive to this type of radiation than others (Fahey, 2012). • Maintaining the Highest Level of Safety with NM Workers in nuclear medicine should follow safety rules. While working with radioactive materials, personal protective equipment like gloves, protective eye wear and cloths and in some cases fume hoods must be used.
These chemicals might not suit every skin type. Chemical peels and chemicals such as salicylic acid are used in various cosmetic procedures and these can cause a lot of irritation and damage to the skin. Many of the bleaches used to whiten the skin and some facials can also cause the skin to burn.
There can be a direct DNA damage by radiation resulting in death of cells. The DNA damage can also be indirectly caused by reactive free radicals generated by the action of ionizing radiation on water molecules. This results in release of multiple cytokines like IL 1, IL 6, TNF beta etc., resulting in mucosal erythema and edema. Eventually the mucosal ulcers get covered by thick exudates forming a fragile pseudomembrane. RT also affects the salivary gland functions reducing and altering the salivary composition.
Antimalarial drug is “used to treat skin rashes, mouth sores and joint pain. While it protects against skin damage from ultraviolet rays in sunlight and may protect your body against organ damage linked to lupus” (webmd.com). Corticosteroids is another drug that is prescribed when the lupus disease has infected your heart, lungs, kidneys, brain or blood vessels. It is a more serious drug, which is why it can prevent long term organ damage. But like all strong prescriptions they have serious side effects.
Steroids come with side-effects only when they are abused. When they are abused, they work in a detrimental manner and can ruin an individual psychologically, physically, and emotionally. Physically it can damage the liver because it detoxifies the body. Over use of it will break down the liver until it doesn’t work. Other side-effects of abuse of steroids,”… liver tumors, jaundice, fluid retention, deepened voice, cessation of the menstrual cycle, growth of facial hair in women, impaired judgment stemming from feelings of invincibility, baldness, and reduced sperm count in
Sunglasses at MBIS? Kiera O’Malley The sun is a very powerful object that can benefit us enormously. However, the Sun can also negatively affect us and our eyes in particular can be severely damaged. Should students at MBIS be allowed to wear sunglasses or would doing so cause many problems? The Sun can cause problems for our eyes.
Slow reacting chemicals are behind the vibrating sound effects. So, whistles and warbling sounds are due to the chemicals reacting slower to the heat. On the other hand, fast reacting chemicals instantly go from a solid to a gas, creating an explosive effect. This in turn, creates a shock wave of sound and causes the bangs, and the thuds. Here’s a more detailed look of the most commonly used sound
Many chemicals that could be harmful to you are not just the ones they put into the ground, but some that come up from the ground can also harm you. Chemicals such as radioactive materials, bromide, heavy metals, hydrocarbons such as BTEX, highly concentrated salts, and other inorganic and organic compounds (Is Fracking A Good Idea?) If these are exposed to the environment they can be deadly health hazards. These such chemicals are dangerous to more than the environment, they are deadly to people
