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? Answer and Explanation: The atomic number is equal to the number of protons in an atom. ...
However, if the element is known to be within a certain part of the list, the start and end parameters can be used to narrow the search. For example: >>> import timeit >>> timeit.timeit('l.index(999_999)', setup='l = list(range(0, 1_000_000))', number=1000) 9.356267921015387...

Remember, subscripts in a formula indicate the number of atoms. If there is no subscript, it means there is only one atom of that element in the formula. Multiply the number of atoms of an element by its atomic mass. Do this for all the atoms and add the values to get the number of...
