Atom of thorium loses 2 protons what element is left?

If an atom of thorium loses 2 protons, it would turn into an atom of protactinium. Thorium has an atomic number of 90, so losing 2 protons would change it to an atomic number of 88, which is protactinium.


Why atomic mass of an atom is defined as relative atomic mass?

It is calculated as the ratio of the mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. In fact, the weighted average of the mass of an atom of an element - weighted according to its isotopic abundance.
