Answer 2

Atomic mass and Atomic number

Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

Uranium and Chromium

238.02891 u

Uranium/Atomic mass

and

51.9961 u

Chromium/Atomic mass
