The Atomic Mass of the isotope uranium-238 is 238,050 788 247 ± 0,000 002 044 (Audi, Wapstra & Thibault-2003).
What else can I help you with?
Decaying unstable element?
Uranium238
Where can the most mass be found in an atom?
Essentially all of the atom's mass is in the nucleus. In the lightest atom, that of hydrogen, it's about 99.95 percent. In the heaviest naturally occurring atom, that of Uranium238, it's about 99.979 percent.
How does the explosion of a nuclear weapon occur?
Most of them begin the same way- a "less than critical mass" of fissile material- usually plutonium- is squeezed by specially shaped high explosives into a "greater than critical mass". This permits an exponentially increasing nuclear chain reaction to take place- plutonium breaks apart into lighter elements, releases energy that breaks more plutonium into lighter elements, and releases tremendous energy as heat and radiation. Fusion weapons use this as the igniter to begin fusing very light materials (hydrogen) into heavier elements, releasing even greater energy as heat and radiation. There can also be a third stage that uses the very high energy fusion neutrons to break apart (fission) materials that normally do not fission, such as Uranium238.
How is mass different from mass?
Mass and mass are the same thing.
How do you find a mass by difference?
Mass of the contained material = Total mass (mass of the container + mass of the material) - Mass of container
What is the formula for mass percent?
mass % of element X = mass of element X ____________________ X 100 total mass of compound or mass of solute _____________________________ X 100 mass of solute + mass of solvent
Does mass have mass?
Yes, mass has mass. It is, therefore, matter. If mass did not have mass, then it is "something" with no mass. That would make it "non-matter" and perhaps it might be energy.
What properties stay the same during physical and chemical change?
mass mass
What is the relationship between center of mass and mass distribution?
The center of mass is the point where an object's mass is considered to be concentrated. The mass distribution refers to how the mass is distributed within the object. The position of the center of mass depends on the mass distribution of the object.
What determines an element's mass?
the mass of protons + the mass of neutrons = mass of the element
How do you solve for percent by mass?
reg.% by mass mass% m/m mass of solute mass of solution=x100
What are the three other names for Midnight Mass Dawn Mass and Christmas Day Mass?
Angel's Mass, Shepherd's Mass, and Mass of the Divine Word.
