#"32 atomic mass units"#.


The nuclide would be #""^32Ne#. How did I know the identity of this element, and why could I ignore the mass of the of the electrons? Note that such an isotope is unknown, and the question does not reflect physical reality.

The quesion should have asked what is the mass and identity of an element that has #"10 protons and 10 neutrons?"# If you have actually copied down this question correctly, the source is highly suspect.
