What is an atomic number and an atomic mass?
... If you know the atomic number of an element, you also know the number of electrons in an atom of that element - they are both the same. They are the same because an atom has neither a positive nor a negative charge. It is neutral. In order for an atom to be neutral, the positive charges of the proto ...
