How are the isotopes of an element similar? a. atomic number b. atomic mass c. atomic mass number Atomic Number: The atomic number of an element represents the number of electrons or the number of protons in the element while the atomic mass represents the su...
What is the cyclotron made of? How large is a PET cyclotron? How many joules are in a watt? How much energy does a quasar give off? How does a cyclotron produce protons? An electron has an energy of 2.3 eV. What is the kinetic energy of this electron in joules?
Artillery barrels are made of extremely strong hardened steel so that they can withstand the repeated blasts of artillery shells when they are fired. Inside this steel casing is nearly 650 pounds (295 kg) of tritonal explosive. Tritonal is a mixture of TNT (80 percent) and aluminum powder (...
How do radioactive isotopes differ from isotopes? Atoms: All of the elements that we know to exist are listed on the periodic table. If you notice, the atomic masses of each element are different, and they are generally decimal values. This value is the weighted average of each isotope for...

I think of these probably-defunct devices as my own rough equivalent of nuclear waste, but instead of radioactive isotopes they may hold old personal data that I don’t want to see leak out. That’s “may” because unlike spent reactor fuel that we know has to be kept safe, these gadg...
Atoms of both isotopes of copper have 29 protons, but a copper-63 atom has 34 neutrons while a copper-65 atom has 36 neutrons. Both isotopes act and look the same, and both are stable. Radioactive Material The part that scientists didn't understand until about 100 years ago is that ...
The chemical composition of rainfall changes slightly as rain clouds move.Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes (同位素). The heaviest rain falls first. As a result, storms that form over the...
Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called ions. Atomic symbol: The atomic symbol (or element symbol) is an abbreviation chosen to represent an ...
