Nolan Mullen · Answer 1

The mass number is the sum of the protons and neutrons in an atom. 235-92 = 143 neutrons.

Element 92 is Uranium.

Uranium is also the highest atomic number element which exists in nature. All of the rest above element 92 only exist nuclear high-energy reactions (the transuranium elements), and most experience nuclear decay very quickly and form other elements with fewer protons.
