Using the following general equation for a nuclear reaction, complete the statements below. the atomic number for uranium is? the mass of the reactant neutron is ? the atomic mass for krypton is? there are ? barium neutrons. the number of neutrons this reaction emits is ?

Atomic number is written in subscript:
Uranium atomic number =92

Mass of neutron is the superscript value times the quantity (moles):
3*1= 3

Atomic mass is approximately equivalent to the number of protons and neutrons in the atom (the mass number). It's written in superscript:

Kr=92

No. of neutrons = Mass number (in superscript) - Atomic number ( in subscript)

= 141-56= 85

No. of neutrons in reactants are: 3
