The uranium within these items is radioactive and should be treated with care. Uranium's most stable isotope, uranium-238, has a half-life of about 4,468,000,000 years. It decays into thorium-234 through alpha decay or decays through spontaneous fission.
<h2>Answer : Option D) Solutions of salt and water conduct electricity.
</h2><h3>Explanation :</h3>
The best description of salt is that when they are dissolved in water they dissociate into ions and become electrolytic in nature. This is observed that these solutions of salt will conduct electricity. Dissociation of ions helps the solution to conduct electricity. Usually salts dissociate into respective cations and anions of the salt compound. Most of the salts can be obtained as a product from neutralization reactions.
