He writes of the possibilities of a catastrophe that can occur if uranium is mishandled. This means that Einstein’s stance on the topic of uranium usage is more educated than others who seemed to not realize the outcomes of using uranium badly. “This new phenomenon would also lead to the construction of bombs, and it is conceivable--though much less certain-- that extremely powerful bombs of this type may thus be constructed”, Einstein writes. Einstein included this to portray the power of the bombs that could be created out of the uranium. This shows the problem with the uranium and what it could and will be used for.…

This element was originally named niton after the latin word for shining like nitons. Radon means or chemical element of atomic number of 86 and rare radioactive gas by the following of noble gas. The atomic mass is 222 for this element. There is 86 protons a nice almond and 136 neutrons. There is usually today eight electrons pair a shell. This element is a nonmetal and that means that it This element is a nonmetal and that means that it doesn't have anything to do with a metal substance.…
Henri Becquerel became the first to discover radioactivity, gamma rays, and alpha and beta particles by studying uranium and other radioactive materials. Becquerel believed that Uranium phosphoresced, or absorbed energy from the sun and then emitted it in the form of light and radiation. He tested this by leaving Uranium salts, or potassium uranyl sulfate, in the sun for several hours and then leaving it, along with a coin, on a photographic plate. A photographic plate was used as an early photograph taking device. It was paper thin and darkened when it came into contact with light. When Becquerel left the plate with the Uranium salts on it he saw that ,once the plate was processed, it was blackened where the Uranium salts were placed. When Becquerel did this experiment again, it was a cloudy day, and the Uranium salts received little sunlight.…
The atomic mass is 99 and the element is technetium (Tc). Atomic mass is found by adding the neutrons and protons.…
The atoms have a nucleus with protons and neutrons in it and then electrons that orbit around the nucleus all atoms are identical with 29 protons and 29 electrons. Since the atomic mass of copper is 63.55, there must also be 34.55 neutrons in all copper atoms. Only one isotope of copper is possible since all of the atoms will have the same nubmer of nutrons. Protons and nuetrons have a lot larger mass than electrons so they occupy the most volume in the atom. Since copper is in the third period in the periodic table the 29 electrons are distributed as evenly as possible between these three shells that means roughly 10 electrons per shell. Since there are only 29 electrons and the first shell is smaller, it will have 9 electrons in it with 10…

An Isotope is an element with the same number of protons and electrons but a different number of neutrons. RADIOACTIVE ISOTOPES the nucleus decays spontaneously giving off particles and energy. Useful for tracing cells in the body when they pick up this radioactive isotope.…
Promethium is the 61 element of the periodic table. All of its isotopes are radioactive so scientists can’t work with it with out the proper gear. An isotope is any of two or more forms of an element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights.…
Isotopes are the atoms that have in their nucleus an atomic number corresponding to the chemical behavior of that element. Since isotopes have the same number of protons, they all have identical chemical behavior. But, however, since their neutron numbers are different the isotopes of the same element may have different radioactivity. An isotope that is radioactive is called a radioisotope like iodine, which is important in our health. In radioactivity, the nucleus of an unstable isotope or element breaks down by itself and gives off rays and particles; the ratio of neutrons to protons for stable isotopes increases for heavier elements and the ratio for stability for the most stable isotopes.…
