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
the atomic mass number for uranium is 92
Uranium atomic number: 92 Uranium atomic weight: 238,02891 Uranium number of protons: 92
The atomic weight of uranium is 238,02891(3) atomic mass units. 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
Atomic mass number = Number of protons + Number of neutrons Number of protons of uranium nucleus is 92. The number of neutrons is different for each isotope. Example for 238U: 92 protons + 146 neutrons = 238
Atomic weight (not mass) of uranium is 238,02891.
the atomic mass number for uranium is 92
Uranium atomic number: 92 Uranium atomic weight: 238,02891 Uranium number of protons: 92
The atomic weight of uranium is 238,02891(3) atomic mass units.
The atomic weight of uranium is 238,02891.
The number of protons is equal to the number of electrons and the atomic number. The number of neutrons is different for each isotope (number of neutrons = atomic mass of the isotope [or mass number] - number of protons).
The atomic weight of uranium is 238,02891(3) atomic mass units. 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
Atomic weight (not mass) of uranium is 238,02891.
Atomic mass number = Number of protons + Number of neutrons Number of protons of uranium nucleus is 92. The number of neutrons is different for each isotope. Example for 238U: 92 protons + 146 neutrons = 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.
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.
The atomic weight of uranium (not mass) is 238,02891.
The atomic mass of uranium 238 is 238,050 788 247
