<h2>Isotopes of uranium</h2>
Uranium is a naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth's crust. The decay product uranium-234 is also found.

It is made of liquidy molten iron that is very hot.
Aspartate directly donates a nitrogen atom from the formation of urea during the urea cycle.
The argininosuccinate synthase reeaction links aspartate and citrulline via the amino group of aspartate and provides the second nitrogen of urea.
Answer:
C. The electrons are closer to the atom with the higher
electronegativity.
Explanation:
In a covalent bond, the electrons are shared equally when the atoms involved have the same electronegativity. However, when there are differences of electronegativity between those atoms, the electrons preferred are closer to the atom with the higher electronegativity.
