What determines the atomic number of an atom? A. Number of electrons in the other shell. B. Mass of the atom. C. The number of neutrons. D. The number of protons. E. The number of protons plus neutrons. How many neutrons does elem...
Note that the mass number of lithium is 6.94, representing the sum of the numbers of protons and neutrons in the nucleus of one atom. Step 3 Note that the mass number is equal to the mass (in grams) of one mole of lithium; this is the molar mass of lithium.Determine the Molecular ...
the researchers were looking to determine how many neutrons could be added to a nucleus before they stop sticking to one another, leading to dripping out. Such a limit is known as the dripline. Prior researchers have already found the dripline for a number of elements—all eight...
What two pieces of information do you need from the periodic table to help you determine the number of neutrons within an atom?The half-life of P-32 is 14.3 days. How much radioactive iosotope would be left after 6 half-lives if the mass of the original sample w...
