Mass number is the number of protons and neutrons in the nucleus of an atom. And we might consider that the mass number of europium is 153 and call it good. Europium has an atomic number of 63, and there is only one stable isotope of it - europium-153. This isotope has the 63 protons and 90 neutrons. But there are other isotopes of europium, and their mass numbers range from 130 through 167 because europium has isotopes with neutron counts from 47 through 104.

superscript 63 and subscript 152 Eu (the super and subscript go before the symbol with superscript on top of the subscript)
Depending on your meaning, it is; 1.772 (rounded), 1.772 (rounded), 1.772 (rounded), 1.772 (rounded), 1.772 (rounded), 1.772 (rounded), 1.772 (rounded), 1.772 (rounded), 1.772 (rounded), 1.772 (rounded), Or 17.72 Or 5.60357(Rounded)
It is rounded to 1 - when rounded.
The answer depends on the degree to which it is to be rounded.
