The elements were organized by Dimitri Mendeleév. He organized them by properties (columns), groups (horizontal), and atomic number (the number of protons and electrons). This became known as the Periodic Table. And currently there are 118 elements. He also found gaps in which elements that were yet to be discovered were to go, three of these unknown elements were found and identified in Mendeleév's lifetime. The elements today are used in everything and 75% of the 118 elements are metal.

According to Carolyn Ruth, author of “Where Do Chemical Elements Come From,” chemical elements came from the explosion of stars, also known as supernovas. In her article, Carolyn states that a newborn star is mainly composed of the first element on the periodic table, Hydrogen. Due to the high pressure within the star, a fusion process begins that fuses two protons and two neutrons together to form the second element, Helium. These fusion processes continue to form elements that weigh less than Iron. Once the star creates all elements up to Iron, the star eventually collapses and explodes. One article that agrees with Carolyn’s theory is “The Origin of the Elements and the Life of A Star”. According to this article, stars produce nuclear reactions

The pioneering work of Becquerel in 1896 (the discovery of uranium), and the Curies (who subsequently discovered radium and polonium and the energy and heat given off by these new elements which they called radioactivity) led to the remarkable work of Ernest Rutherford. He was a physicist, whose experiments showed that some heavier elements spontaneously changed or decayed into lighter elements (unstable 'parent' elements giving off protons and neutrons to form a 'daughter' element) through the process of radioactivity. He discovered that radioactive materials decay at a very predictable rate, and that lead was the final decay product of uranium. Using Rutherford's ideas, Bertram Boltwood pioneered a method of radiometric dating in 1907. He hypothesized that since he knew how long it takes uranium to break down, he could measure the proportions of lead in uranium ores, and use his calculations to date how long those ores had existed,

The United Brotherhood of Carpenters and Joiners of America, UBCJA, is a labor union that advocates for worker rights. Founded in 1881, Peter J. McGuire and Gustav created the union in response to the lack of worker right laws in place. Since then, the union has grown substantially in size but still, lobbies for workers’ rights. The union lobbies for issues on a regional and national level. They have endorsed and contributed finically to presidential candidates. They have also endorsed and contributed finically to congressional candidates across party lines who they believe will help fight for worker rights. The union also provides several services to its members such as training, a pension fund, and welfare. The UBCJA has long fought for workers

Besides being entranced with the golden dome, “touchdown Jesus” also found a place in my heart. The Hesburgh Library is one of the most beautiful buildings on campus. It is appropriately named as well. Fr. Hesburgh was an influential leader on campus and throughout the world; he was an advocate for peace rather than violence. Under his tenure, the first female class was admitted into the university, and after serving as president, he was able to witness the first African-American valedictorian. I am sure a dream of Fr. Hesburgh was fulfilled on that spring day. Even after the Civil Rights Act of 1964 was passed, he continued to fight for equality in housing, employment, and higher education for minorities. Hesburgh’s attitude toward equality

Uluru is the biggest rock in the world. It is 9.4km if you walk around it and about 345 metres high if you climb it. It's 3.6km long, 2km wide, and is a roughly oval shape. It's made of arkosic sandstone and is renowned for the way it changes colour in the light and is particularly spectacular at sunrise and sunset.

The first person in my family that was born in Mexico is my dad. His name is Renan Uribe and he’s an excellent dad. Renan Uribe was born on November 12, 1971, in Jalisco, Mexico with his other 11 brothers and sisters. Each of his siblings is unique in their different ways since they all are either blonde with green eyes or blonde with light brown eyes. On the other hand, my dad was very different from them, he has light brown hair and light brown eyes! Uribe’s life was difficult. My dad didn't have an education, therefore, he grew up on the field helping his father, Maximino Uribe, while his mother, Rufina Pelayo, stayed at home watching over her children. When he was an adolescent he worked at a taqueria and played soccer. At age 17, Uribe

On August 2, 1939, Einstein proposed an interesting to President Franklin D. Roosevelt. This idea, called the atomic bomb, would change the lives of everyone. Making it was easier said than done, though. They needed a team of scientists: Robert Oppenheimer, David Bohm, Leo Szilard, Eugene Wigner, Felix Bloch, Otto Prisch, Rudolf Peierls, Niels Bohr, Emilio Segre, James Franck, Enrico Fermi, Klaus Fuchs, and Edward Teller. Then they had to find U-235, which looked exactly like U-238, a useless material. The process was hard, especially since only mechanical methods worked. Finally, after an extraction system, a magnetic separation, and a gas centrifuge, all that was needed to be done was to test the entire concept in the deserts of Jornada del Muerto (about money).

As a collaboration of lab work went on they planned on setting up “a nuclear chain reaction in a large mass of uranium,” which would generate “new radium- like elements.”

It was first developed in the 1940s, and during the Second World War to 1945 research initially focussed on producing bombs which released great energy from the atoms of particular isotopes of either uranium or plutonium.

Uranium was discovered by Martin Klaproth in 1789. Klaproth was a German Chemist that discovered Uranium in a mineral call pitchblende. It was named after Uranus, the planet, which had been discovered eight years earlier. Uranium occurs in most rocks in concentrations of 2 to 4 parts per million and is common in the Earth’s crust. This highly density element is used in keels of yachts and as counterweights for aircraft control surfaces, as well as for radiation shielding. This element principal uses is in fuel for nuclear reactors and the main raw material for nuclear weapons. Depleted uranium is the waste product of uranium enrichment in nuclear reactors. It is the residue left in massive quantities when bomb-grade uranium is

They now began the tedious and monumental task of isolating these elements so that their chemical properties could be determined. During the next four years, working in a leaky wooden shed, they processed a ton of pitchblende, laboriously isolating from it a fraction of a gram of radium.      In 1903,

     In July of 1898, Marie and Pierre Cure discovered Polonium. They named the element after Marie's birth country, Poland. Chemically, this new element was very similar to bismuth, but it contained radioactivity, so it must be new. In December of 1898, the Curie's discovered yet another element. They named this one radium, from the Latin word for ray. The two new elements had completely different chemical properties, but they both had very strong radioactivity.

This is what led Curie to take Becquerel’s work a few steps further and conduct her own experiments on uranium rays. She discovered that the rays were constant no matter what form or condition of the uranium. She theorized the rays came from the atomic structure. This idea was revolutionary and created its own field in science, known as the atomic physics, this is when Marie coined the word “radioactivity” to describe the phenomena. Even when they had their first daughter Irene in 1897 there work did not slow. Pierre then stopped his own studies to help Marie with her new discovery of radioactivity. In 1898 they discovered a new radioactive element. They named it polonium after Marie’s native country, Poland. They detected the presence of another radioactive element and called this radium. In 1902 they had extracted pure radium to prove its existence as a unique chemical element.
