The purpose of this investigation was to find the average atomic mass for the element Beanium with three isotopes. The average atomic mass is the average mass of the atoms of the element divided by the total number of atoms. An isotope is an atom with the same number of protons, but different number of neutrons; they are different forms of a single element. Since we knew the isotopes had almost the same amount of sub-atomic particles, we made our hypothesis the following: If the sub-atomic particles are almost exact in amount the total mass, average mass, relative abundance, percent abundance, and the relative mass were also going to be almost exact.…
The study parameters included patients on this medication between 1/10/2011 and 1/10/2012, ages 0-100, Eltroxin dose 25mcg, 50mcg, 75mcg,100mcg, 125mcg and 150mcg. This list of patients was printed out based on medication dose. The individual patient files were examined with particular reference to the frequency of thyroid function testing in the specified audit period. The results were entered into an excel file. A reaudit period existed from 1/10/2012 to 30/04/2012. Patients who did not have a thyroid function performed or who had an abnormal result were followed up to check improvement in adhering to the…

An isotope is a variation of an atom that already exists. An isotope is different from an atom because of the number of neutrons in its nucleus. Finding the amount of neutrons in an atom can be calculated by subtracting the atomic number of a specific atom from its atomic mass. When looking at the periodic table, the atomic mass in the top left corner of every box is a decimal. The mass is in decimal format because the number listed is an average of that atom, plus all of its isotopes. Isotopes have different masses because neutrons weigh 1 amu where as an electrons weight would be negligible. The experiment described below shows how including all isotopes of one element effect the average atomic mass of the element.…
This element was discovered by Friedrich ernst Dorn a German Chemistry. It was founded in 1900. It was discovered while studying Radion Dk chain.…
Explain how the atomic number and mass number of an atom can be used to determine the number of neutrons.…
Atomic number is derived from the number of protons in an atom. Example, Helium, (H) = 1. The number of protons in an element is constant (e.g., H=1, Ur=92) but neutron number may vary, so mass number (protons + neutrons) may vary. However, the same element may contain varying numbers of neutrons; these forms of an element are called isotopes. The chemical properties of isotopes are the same, although the physical properties of some isotopes may be different. Some isotopes are radioactive-meaning they "radiate" energy as they decay to a more stable form, perhaps another element half-life: time required for half of the atoms of an element to decay into stable form. Another example is oxygen; with atomic number of 8 can have 8, 9, or 10 neutrons.…
You may have noticed on the periodic table that the atomic mass of an element is usually not a whole number. That happens because of isotopes. An atom that is missing a neutron or has an extra neutron is called an isotope. They are still the same element; however, they are just a little different from every other atom of the same element.…
The atomic mass is 99 and the element is technetium (Tc). Atomic mass is found by adding the neutrons and protons.…
Iodine is relatively insoluble, but this can be improved by complexing the iodine with iodide to form triiodide as the following formula suggests:…
Iodine is an element on the periodic table. It has an atomic number of 53. Iodine is used very often in natural history and is used to find starch, which will be needed in order to conduct this experiment.…
The atomic mass is 151.96. To find the atomic mass of an element, first they have to see how many protons and neutrons contained. There are 63 electrons and protons in Europium and 89 neutrons. Now this item is not something that you can easily pick up anywhere. You’ll have to save up a couple paychecks, and also a couple of birthday cards. For one kilogram europium could cost up to $1600-$1700, that’s just for one kilogram.…
