Uranium has three natural isotopes and many artificial isotopes.
Uranium 238 has 92 protons and electrons and also 146 neutrons.
The answer is 15,2.1021 atoms of uranium.
156,86.1020 atoms of uranium in 6,2 g uranium
1 nanogram of natural uranium = 2,53.1012 atoms
The answer is 0,1518.10e+23 atoms.
9.6 grams of uranium (1 mole U/238.0 grams)(6.022 X 10^23/1 mole U) = 2.4 X 10^22 atoms of uranium
The answer is 15,2.1021 atoms of uranium.
156,86.1020 atoms of uranium in 6,2 g uranium
1 nanogram of natural uranium = 2,53.1012 atoms
Uranium atoms are split during nuclear fission. Uranium-235 and uranium-233 are fissile with thermal neutrons and uranium-238 is fissile with fast neutrons.
113 662.1016 uranium-234 atoms
Uranium (as an element) has atoms, not molecules; uranium compounds are molecules.
Uranium
7,5.1021 uranium atoms = 2,9644 grams
The answer is 0,1518.10e+23 atoms.
The uranium atom has seven electron shells.
Uranium isotopes
Uranium-238 and uranium-234 are not "elements", but they are natural isotopes of the chemical element uranium. The atoms are neutral.
