Polonium Essays

Polonium (Po) Polonium is highly radioactive element, and has a had a rich history in the world of chemistry. It was the first element ever that Marie Curie and Pierre Curie discovered. It was discovered in 1898, in poland, its namesake. Polonium has a total of 33 isotopes, all radioactive, and making it one of the elements with the highest isotope count. The atomic number of polonium is 84. The average atomic weight is 209. Polonium has 84 protons, 84 electrons, and 125 neutrons. The most

couple's love for each other changed the flow of history in many different ways, making discoveries, winning prizes, and influencing people today. Marie and Pierre Curie discovered radium, polonium, and isolated radium salts from the mineral pitchblende, in the article it states, “The Curies discovered polonium and radium. In 1902 they successfully isolated radioactive radium salts from the mineral pitchblende.” Then this couple had won a Nobel Prize in physics from groundbreaking discoveries in radioactivity

high radioactivity, which were the bismuth and barium fractions of the pitchblende. They then concluded that there had to be two new elements inside these areas that caused the radiation, since the concept was new. They named the element in bismuth polonium, after Marie’s homeland of Poland, and the element in barium radium, after the Latin word meaning

It’s is located in period three, group sixteen. Sulfur is in the Oxygen family. Its family members are oxygen, selenium, tellurium and polonium. The first four are nonmetals and are called the chalcogens. In this group only sulfur has a strong tendency of catenation. Oxygen also shows this tendency to some extent. All these elements belong to p-block elements. Polonium has metallic character and it is a radioactive material with very short period.

There are many physicists that discovered or brought something to the world that changed it forever. But who were the physicists that actually won the Nobel Prize for physics? Max Born? Otto Stern? Albert Einstein? The first one I am going to talk about is Albert Einstein. Einstein was born on March 14, 1879. He specialized in math and physics. Einstein invented or discovered many things but the thing he is most known for is the part he played in developing the atomic bomb in the 1940’s. Why? Einstein

An old pass time. Sitting down after a long day of work and placing a cigarette in your mouth. Consumption of tobacco, an abundant plant in the Americas, has been dated back to about 1 B.C.E. (Randall). Many people took part in tobacco use starting when Europeans discovered the New World in the 1400’s (Randall). There are two key ways for tobacco to be used. They are smoking and chewing. In the 1950’s, it was discovered that the common cigarette is tremendously harmful to human health and even contains

In the sixth chapter, Kean starts with Henry Moseley, the man who found a mathematical relationship between the elements atomic number, wavelengths of x-rays, and the number of protons an element has. After Moseley death, scientists began to hunt down the missing elements that Moseley mentioned thus making the periodic table bigger. Kean then moves on to the Manhattan Project in which veterans came up with bombs using cobalt that could extinct mankind. In the seventh chapter, Kean focuses on the

also alkaline earth metals such as magnesium, radium, and calcium. There are transition metals like titanium, iron, cobalt, and zinc. There are basic metals such as aluminum, tin, and lead. Next there are semimetals such as boron, silicon, and polonium. Nonmetals include carbon, oxygen, phosphorus, and nitrogen. Noble gases

Marie Curie, originally named Maria Sklodowska, was born on November 7, 1867, in Warsaw, Poland. In her family, the five children - Marie Curie being the youngest - were nurtured by their mother and father, renowned teachers who taught at Warsaw universities and at Lublin University. Marie followed in the footsteps of her father, a math and physics professor, by pursuing her interest in physics and chemistry. At a young age, Marie discovered her love for physics and wished to pursue further education

is to make each and every cable the same length which is why the Gadget looks like a ball of wires. Assembly of the nuclear capsule began on 13 July 1945 at the McDonald Ranch House, where the master bedroom had been turned into a clean room. The polonium-beryllium “Urchin” initiator was assembled, and Louis Slotin placed it inside the two hemispheres of the plutonium core. Cyril Smith then placed the core in the uranium tamper plug, or “slug”. Air gaps were filled with 0.5-mil (0.013 mm) gold foil

in the pitchblende. (a mix of ores) The discovery of more new elements, even got Marie’s husband excited and her husband Pierre put his own research aside to help Marie. By 1898 they had discovered two elements which were Polonium and Radium. She came up with the name Polonium from her home country of Poland. For radium since it was the most radioactive it got rad from the radiation. Pierre found that when he put the glass vial of radium on his skin it would turn his skin red. This would tell us

the words I live by and what has helped me throughout the years become who I am today. Hello! or as they say in Poland, “Cześć!” My name is Marie Curie. I am a physicist and chemist, most famous for discovering the chemical elements of radium and polonium, and opening a new field for women in science. I was married to Pierre Curie, another famous scientist, who assisted me in my discoveries. I was a woman in a time when women were not scientists, and this is the story of my success as one. I fought

These free neutrons were introduced by creating a neutron generator. The generator is a small pellet consisting of beryllium and polonium separated by foil within the fissionable fuel core. Neutron Generator- 1. The foil is broken once the subcritical masses come together and polonium spontaneously emits alpha particles (ionizing radiation ejected by the nuclei of some unstable atoms) 2. These alpha particles clash then interact with the beryllium-9 producing

Democritus, a Greek Philosopher: 460 BCE, Developed the idea of atoms Aristotle, a Greek Philosopher: 348 BCE-322 BCE, Stated that matter was continuous – no atoms Robert Boyle, an Anglo-Irish Philosopher: 1627-1691, Created the “Boyle’s Law” (named after himself), which stated that the pressure and volume of a gas have an inverse relationship only if the temperature isn’t or doesn’t change Antoine Lavoisier, a French Chemist: 1743-1794, Identified the elements oxygen and hydrogen, also identified

The industrial revolution had the greatest impact on education, science and technology, and the society which, drastically changed the course of history unlike any other event from thousands of years. During the industrial revolution, public education started to be revamped in order to make social progress and reduce poverty. In Science and technology, Marie Curie discovered the atomic theory, and The Wright Brothers invented the first model of the airplane. The most important change of society

achievement, that propelled her scientific platform, was her discovery of the 88th element of the periodic table, Radium. “Though her most well-known contribution to science was of unrivaled status, she also published her finding of element number 84, Polonium, in July 1898, which preceded her discovery of Radium in the following December” (Pasachoff). Her eye-opening revelation to the scientific community was the product of many years of hard work alongside her husband, Dr. Pierre Curie. Along with a

Curie’s selfless desire to make progress in the field of science for the benefit of society along with the aid of her husband led her on the path to discovering radium; forever altering the field of science and medicine. Marie Curie devotedly worked towards improving the world’s knowledge of the science field accompanied by Pierre even as the temptation of profit emerged. On the hunt for someone with more experience than her, Curie sought help from a young-novice researcher named Pierre to provide

Nuclear Fusion occurs when nuclei combine to make the nucleus a greater weight. In fusion reactions, a small nuclei combine and release more energy than they do in the fission reactions. In fission reactions the large nuclei split into pieces. Fusion reactions occur at high temperatures such as 40,000,000 degrees Celsius. Fusion is used to produce nuclear bombs with the high temperatures in the bombs requiring them to initiate fusion reactions. An uncontrolled fusion device is the triggering device

Shortly after X-rays were discovered in 1895, Antoine Henri Becquerel (1852-1908) tried to show the relationship between X-rays and phosphorescence of uranium salts. In one of his experiments a photographic plate wrapped in black paper, placed a sample of uranium salt on it and exposed to sunlight. By revealing the plot appeared that the rays emitted by the salt had penetrated through the paper. Later, Becquerel was preparing to repeat the experiment, but as the sunlight was intermittent, placed
