We have compared the results produced by a variety of currently available Monte Carlo neutron transport codes for the relatively simple problem of a fast source of neutrons slowing down and thermalizing in water. Initial comparisons showed rather large differences in the calculated flux; up to 80%...
How to calculate Bohr radius How is the mass of the up quark measured? How is the number of neutrons in the nucleus of an atom calculated? Determine the electron to baryon ratio in the universe, noting any assumptions. What quantity would be used to measure the amount of work a single ...
How does an atom try to fill its valence shell? If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons? Explain the concept of the mole. How many electrons does aluminium have? Calculate the number of mole...
To calculate the molecular mass of a compound, you need to know two things. The first is the molecular formula, and the second is the atomic mass number of each of the elements that comprise it. The atomic mass number for each element is listed in atomic mass units under its symbol in...
For the mass section I'm not sure if I need to calculate the critical mass to determine how much solution (which contains some plutonium nitrate) should go in a storage drum. I don't know how to do this. Homework Equations I have calculated that there is 36.5 gallons of liquid in the...
Knowing the relative fraction of each isotope of a particular element that occurs in nature allows you to calculate the atomic mass of that element, which, because it is an average, is not the mass of any one atom but a number that is between the heaviest and lightest isotopes pres...
How do you calculate half life? How to determine the rate of decay? How many years would it take for an isotope to be completely non-reactive if the isotope had a half life of 200 years? How would you figure this problem when you are not given a starting amount of sub ...
Electron volts are a common unit of measurement in particle physics to describe the potential energy of the system and balance conservation of energy. We might talk about the rest mass or momentum of protons, neutrons, muons, pions, or electrons using electron volts. ...
What are the charges of two ions of copper? What is the electronic configuration for the ground state of carbon? How to calculate how many rings are there in an atom? What Is the total atoms in CH_3(CH_2)_8COOH? What are the electron configurations of Na^+, Cl^-, and Ca^2+?
The periodic table of elements includes 118 individual types of atoms (that is, elements), all of which have a unique number of protons and electrons and a similar number of neutrons. But just how tiny is this infinitesimally small entity? Is there a way to relate thesize of an atomto ...
