    Imagine element *W* that looked like this:

    228 amu

    One week after it's discovery scientists noticed that element *W * had 113 protons. Assuming that all previous observations were accurate what could explain this change?

    The atomic weight corresponds to the number of nucleons (protons and neutrons) in the atom's nucleus.

    The atomic number is the number of protons in the nucleus. Since atoms are electrostatically natural, this is also the numbers of the electrons of the atom.
    This number is the main parameter in the atom's electrostatic interactions, and the type of element is defined by this number. Two different elements can have the same number of neutrons but they will always differ in the number of protons.

    Here we started with element W that has 112 ...
