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.
What element in the periodic table has an atomic weight of 912.2?
The element with an atomic weight of approximately 912.2 is uranium (U), specifically the isotope uranium-238. Uranium is a naturally occurring radioactive element with a variety of applications, including nuclear power generation and weapons development.

Whats is atomic weight of uranium-238?
238.02891
How you calculate the relative atomic weight of uranium?
The atomic weight of an element is derived from the atomic masses of the isotopes of this element and from the percentage of these isotopes. The correct terms are: - atomic weight for elements - atomic mass for an isotope
How do you figure out mass?
The Atomic Mass or weight of an isotope of an element is the total number of protons and neutrons in its nucleus. The number of protons defines which element it is, this is called the atomic number. For uranium for example it is 92, but the atomic weight can be from 233 to 238, and these different versions of uranium are called isotopes. See Periodic Table for more details of all the elements. Add the no. of neutrons and the no. of protons to get the atomic mass.
What is the weight of uranium?
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
How is The atomic weight of an atom determined?
The atomic weight of a molecule is the weight of all the molecules in it combined. Example: H20 Hydrogen: 1.01 Oxygen: 16.00 2 hydrogens = 2.02 + 16.00 = 18.02 is the atomic weight of water.
What do the individual squares in the periodic table?
Each individual square in the periodic table represents one element. It gives the chemical symbol for the element. The number for the element, which is the number of protons. It gives the average atomic weight. The atomic weight is roughly the weigh of the protons and the neutrons. For example: Uranium, element number 92, has the symbol U. It has 92 protons. It comes in 3 isotopes or different forms but with the same chemical properties. It comes as U 238, U 234, and U 235. That means Uranium 238 has 92 protons and 148 neutrons. Depending on the periodic table, it may also have other information.
What is the Highest atomic number on the Periodic Table?
The element provisionally named ununoctium, believed discovered in 2003, has atomic number 118 in Period 7, column 18, with an atomic weight of 294. Once confirmed, it will be given its permanent element name.
What is the molar mass of uranium -238?
238 grams/mole The isotopic number is the approximate mass for any element. Such as if I say Carbon 14, the approximate mass is 14 grams/mole. If you are asking what is the mass of one atom of Uranium 238: Then you take the isotopic mass 238 grams/mole and divide by Avogadro's Number 6.022X10^23 atoms/mole this gives you units of grams/atom.
