Isotope

an average of 18.5 neutrons and 17 electrons. It has an atomic number of 17, and an average nuclear charge of 35.5. There are 2 isotopes of chlorine that are 35Cl and 37Cl. 35Cl has an atomic mass of 35 and a natural abundance of 75%. 37Cl has an atomic mass of 37 and a natural abundance of 25%. The average atomic mass or nuclear charge equates to 35.5. Both of the isotopes have the same atomic number. (BBC Bitesize. Atoms and the periodic table. 2014) Gold: Au, Arsenic: As, Molybdenum: Mo,…

both radioactive isotopes, straight into the ocean. Marine life and seafood were both put at risk due to the capability of ocean currents carrying radioactive material out to sea. According to numerous marine biologists this radioactive material can be found in oceans 60 years after they were initially released, and may be detrimental to both marine life and seafood. This disaster affected the marine food chain in numerous ways. For example, the ocean has natural radioactive isotopes such as…

When a neutron is absorbed by isotope of X-- given that X is some given element-- another isotope of X is created. Though sometimes these newly-created isotopes of X are very unstable. They may be so unstable, in fact, that they only exist briefly before splitting into two separate and distinct chemicals. Radioactive photons, massive energy, and neutrons are shot out in the surrounding area. As long as more Isotopes of X still exist in the area, this can, in turn, create a grand chain reaction…

In the article, “Recent Antarctic Peninsula warming relative to Holocene climate and ice-shelf history,” Robert Mulvaney and several scientists discussed the climate history of the Antarctic Peninsula and its relationship to the collapsing ice shelves. They observed that the ice shelves were collapsing which allowed the glaciers to drain ice at a faster rate. The ice shelves that collapsed were at the Antarctic Peninsula which has had the most rapid warming over the past 50 years. Mulvaney and…

This also means that a neutral atom of Copper has twenty- nine electrons. Since the mass of an electron is so small, only the neutrons and protons contribute to the mass of the atom. Copper’s mass number is 63.546 due to its many isotopes. The two most stable isotopes of copper are Copper-63,…

Nuclear Energy Nuclear Energy Nuclear Power Plants: Nuclear Power Plants are facilities which generate electricity through the use of nuclear reactions. It is referred to as a thermal power station because it creates a nuclear reaction, in which a lot of heat and energy is created. Due to the production of heat, the plan creates a lot of steam which is used like in coal or gas-fired power stations to drive turbine generators to generate electricity. Nuclear Reactions The are two nuclear…

Only two electrons can be in an orbital. Student - Doesn’t the P-Orbital set hold six electrons? Mr. Crowder - P-Orbital set includes three orbitals, thus six electrons occupy the set. Mr. Crowder - In order to account for the percent composition of isotopes you must include the algebraic expression (1-x) when completing the calculation.…

Aliens have been a popular topic in American culture for decades, with debates around Area 51, or movies and TV shows like Stranger Things. However, in the 1947 New Mexico summer, some debris was found in a ranch near Roswell. This occurrence was later named “The Roswell Incident”. The Roswell Incident then sparked a debate whether aliens were real, or fiction. The belief that the Roswell Incident was a UFO is an interesting topic that can be supported by witness accounts, the government’s…

shells to prove that DNA was passed down and protein was not. Hershey knew that bacteriophages contained basically two parts, a protein shell, and DNA. He used a radioactive isotope of phosphorus (which phosphorous isn 't found in DNA) to "mark" the DNA of the bacteriophage (Dnaftb, n/a). He then used a radioactive isotope of Sulphur to "mark" the protein in the shell of the bacteriophage. After the bacteriophage, DNA and Protein were marked he released them into containers of unlabeled…

neutrons and starting a self-supporting arrangement of atomic partings, or a chain response, which brings about ceaseless arrival of atomic vitality. Normally happening uranium contains just 0.71 percent uranium-235; the rest of the non-fissile isotope uranium-238. A mass of regular uranium without anyone else's input, regardless of how expansive, can't support a chain response in light of the fact that just the uranium-235 is effectively fissionable. The likelihood that a splitting neutron…
