Atomic number: 92

Standard atomic weight: 238.02891(3) g mol-1

The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope:

234U: mass number 234

235U: mass number 235

238U: mass number 238

Each isotope of an element has a different number of neutrons. Number of neutrons = Atomic mass of an isotope - atomic number of the element For uranium the atomic number is 92; for the isotopes see the list of isotopes with their atomic mass.


What element has the atomic number 238?

There is NO element with the Atomic No. of 238. Atomic No. only go to ~ 110. However, There is an element with ATOMIC MASS of 238, it is an isotope of Uranium NB . Atomic Number refers to #1 the position in the periodic table #2 the number of protons in the element #3 the number of electrons in the neutrally charged element. Atmoic Mass refers to the Sum total of all the protons and neutrons in the nucleus of an element. An element such as Uranium would be shown in the periodic table as [238/92]U. The two numbers indicating the Atomic Mass and the Atomic Number.
