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...
How many protons and neutrons are in the nucleus, and how many orbiting electrons are in the neutral atom? How many protons are in ^{42}Ar? How many electrons in an atom can have each of the following quantum number or sub level designations? n=4, l=3 How many electrons does...
Natural uranium from a mine contains two isotopes: U-235 and U-238. The U-235 is what is needed to produce nuclear power (see How Nuclear Power Plants Work for details), so the uranium is refined to extract the U-235 and create "enriched uranium." The U-238 that is left over is ...
The metal tin, for example, has ten stable isotopes: atoms that have the same number of protons and electrons (50 of each) but different numbers of neutrons. Stable isotopes are ones that are happy enough to stay as they are indefinitely: they have nothing to gain by changing into a ...
Question: How many neutrons and nominal mass for {eq}\displaystyle \rm ^{1}H_2^+ {/eq}? Atomic Mass: The atomic mass of an atom or molecule can be determined based on the "number of protons and neutrons". "The total atomic mass or molecular mass of the atom or a molecule is the...
For example, carbon atoms always have six protons; hydrogen atoms always have one; and oxygen atoms always have eight. 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 ...
Nuclear fusion is a promising way to generate clean and sustainable energy by replicating the process that powers the sun and stars. It involves fusing light atomic nuclei, such as those of hydrogen isotopes, to form heavier ones, such as helium, releasing a vast amount of energy in the proc...
Because enriched uranium is a radioactive substance, there has been concern about the possible health effects of depleted uranium. While depleted uranium does not have the level of radioactivity of enriched uranium, some experts fear that itmight cause health problems. The Department of Defense and...
Nuclear plants aren't sustainable or renewable forms of energy, because they rely on mining limited reserves of uranium. They're not zero-carbon either, because it takes a lot of energy to mine that uranium. Nuclear plants are expensive and take many years to construct, usually in the face...
Both isotopes of uranium are naturally radioactive; their bulky atoms disintegrating over time. Given enough time (hundreds of thousands of years), uranium will eventually lose so many particles that it will turn into lead. This process of decay can be greatly accelerated in what is known as a...
