Stanislaus Ulam was one of the designers who helped improve the H-bomb and made it more powerful. In January 1951, Ulam came up with the idea of placing a hollow tube of uranium or plutonium inside the bomb casing and also used the fission explosive lens assembly (dailykos) . The intense radiation pressures produced by the implosion trigger might, he thought, flood the bomb casing and momentarily produce enough pressure to squeeze the hollow tube into a solid rod, in effect imploding it into a critical mass which would then add to the yield (dailykos). Edward Teller was the other designer who combined his ideas with Ulams’ to make the H-bomb so effective. When Ulam told Teller about the idea, Teller combined them together in order to make the H-bomb more powerful..
Electrons should move around the nucleus but only in specific orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted. Bohr's theory could explain why atoms emitted light in fixed wavelengths. Glenn Seaborg 1941 - 51 Dwight Logan Reid, who was a chemistry and physics teacher, influenced Glenn Seaborg to investigate the atomic theory and he did just that with a successful outcome changing the model of the atomic theory. He was the investigator of isotopes and with this discovered iron, with this finding came the discovery of hemoglobin, which can be found in human blood.
When this happens, some atoms of the mass are split, and the neutrons produced by those splitting atoms strike nearby nuclei of other atoms, causing additional fission to occur. (This is known as a chain reaction.) When these atoms split, immense energy is released as the devastating explosion of the bomb. The gun-type bomb can only be fueled by the uranium isotope, U-235. Little Boy was one of the atomic bombs that were assembled this way and was powered by U-235.
In this letter Einstein wrote about a new study on the chain reactions that took advantage of uranium. He said if done correctly it could produce substantial amounts of power, and if this power was harnessed it would result in a bomb capable of unheard of damage. Einstein also stated that it was believed that the German government
Fullerenes can be described as a molecule of carbon that can take the form of a hollow sphere, ellipsoid or tube. In 1985, Buckminsterfullerene became the first fullerene molecule to be discovered. This discovery was made by Richard Smalley, Robert Curl, James Heath, Sean O’Brien and Harold Kroto at Rice University, Texas and led to Kroto, Curl and Smalley winning the 1996 Nobel Prize in Chemistry. Buckminsterfullerene molecules, otherwise known as Buckyballs were discovered purely by chance, during experiments which produced carbon plasmas by vaporising a graphite rod in a helium atmosphere using a laser. The aim of this experiment was to characterise unidentified interstellar matter and spectrometry evidence proved that carbon molecules of C60 were forming.
He more continued on from “Maxwell’s theory” of electromagnetism than developed it from there in till he got the “theory of relativity”. Albert Einstein’s photoelectric effect started in 1887 with a scientist named Heinrich Hertz which “discovered that electrodes illuminated with ultraviolet light create electric sparks more easily”. Than in 1900 a German physicist named Max Planck proposed “that energy carried by electromagnetic waves could only be released in packets of energy”. Although in 1905 Albert Einstein released a paper in which he progressed the hypothesis saying “that light energy is carried in discrete quantized packets”. Albert Einstein discovered his very famous equation E=MC2 while trying to finish his “theory of relativity”, this equation actually completed Albert Einstein’s “theory of relativity”.
The United States did so in 1952 making a very powerful "hydrogen bomb," a fews days after Eisenhower was elected. The 10-megaton blast of the bomb had destroyed the test island of Elugelab, creating an underwater crater 1,500 yards in diameter. With the hydrogen bomb the United States and the world had entered the thermonuclear age. Thermonuclear means relating to or using nuclear reactions that occur only at very high temperatures, or involving weapons in which explosive force in produced by nuclear
Three years later, Oppenheimer had his second child, which was a girl named Katherine, but her nickname was Toni. In 1942, Julius Robert Oppenheimer started to work on the Manhattan Project, where he became most commonly known as the father of the atomic bomb, because he was the director of the Manhattan Project. The Manhattan Project was the United States building an atomic bomb during the WWII. On July 16, 1945, the first nuclear bomb was exploded with the power of eighteen thousand tons of TNT in the New Mexico desert . After the first bomb was made, two more were dropped into Japan to help end the war.
He is mostly known for his mass–energy equivalence formula E = mc2, which has been recognized as "the world 's most famous equation". ii. Can you give me an example of one of his contributions do science? 1. In the year of 1905, Albert Einstein published a paper advancing the hypothesis that light energy is carried in discrete quantized packets to explain experimental data from the photoelectric effect.
Explain what is meant by relative atomic mass?- Relative atomic mass is the measure of the mass of an element which consists of the protons and neutrons; it is always the bigger number and has the symbol Ar. An obvious example of this is oxygen has the Ar of 16 yet sodium has the Ar of 23. Explain how relative formula mass is calculated using the periodic table- You need to find the relative atomic mass (M) for each atom but this can only be done when the relative atomic mass have been found, then you add all of the masses in the compound together to find the RFM. Sodium Hydroxide is the example we used within our experiment. Na= 23 O= 16 H= 1 NaOH 23 + 16 + 1 = 40 NaOH Mr= 40 Explain how it is possible to work out amounts of substance
These were Atomic physicists (OI ). For example, Robert Boyle suggested that the smallest chemical elements were the simplest forms of matter (Doc. 1). Also, ancient, greek philosophers Leucippus and Democritus were the first to discover atoms. Many others were devoted to the study of atoms, and gave many ideas of what atoms were.
Question # 1: Part A How many electrons and protons in an atom of vanadium? Answer # 1: Atomic number = number of protons = 23 Mass number = number of protons + neutrons Mass number = 51 g/mole Number of neutrons = 51-23 Number of Neutrons = 28 Number of electrons = atomic number = 23 Question # 1: Part B Explain in 2 or 3 sentences how the atomic weight is what is reported. Answer # 1: Atomic weight or atomic mass is basically the average mass of atoms of an element. Atomic mass is calculated by using the naturally occurring relative abundance of isotopes. Atomic weight determines the size of the atom.
Polarity shared electrons get pull away difference in electrical charge at one end as opposed to the other end 2.3 The Ionic Bond 1. Ionic bonding when the electronegativity differences between 2 atoms were so extreme that the electrons were pulled off 1 atom only to latch on to the atom that was attracting them A: What is an Ion? 1. Ion is a changed atom or an atom with the number of electrons different from it number of protons 2. Ionic bonding is the chemical bonding in which 2 or more ions are linked by virtue of its opposite charge 3.
On the first ring there will be 2 electrons and on the second ring there is 8 electrons. That gives them a total of 10 electrons. Along with atomic number, protons, and electrons there is a atomic mass which is 20.1797. Neon was discovered by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, shortly after their discovery of Krypton. Like krypton, neon was discovered through the study of liquefied air.
“Hydrogen bomb or H-bomb, is a weapon deriving a large portion of its energy from the nuclear fusion of hydrogen isotopes. In an atomic bomb, uranium or plutonium is split into lighter elements that together weigh less than the original atoms, the remainder of the mass appearing as energy. Unlike this fission bomb, the hydrogen bomb functions by the fusion, or joining together, of lighter elements into heavier elements. The end product again weighs less than its components, the difference once more appearing as energy. Because extremely high temperatures are required in order to initiate fusion reactions, the hydrogen bomb is also known as a thermonuclear bomb.” The hydrogen bomb is the most powerful bomb ever created.
