Which two actinides occur naturally?
Uranium and thorium are the two actinides that occur naturally in the Earth's crust. They are found in low concentrations and have important roles in various nuclear reactions and processes.
Where does chlorine naturally occur?
Chlorine gas does not occur naturally as it is too reactive. Chloride salts occur naturally. The most common is sodium chloride, NaCl. Chlorine, Cl2, is obtained by electrolysing molten NaCl.
Do magnetic minerals occur naturally?
Yes, magnetic minerals occur naturally in the Earth's crust. These minerals can be found in various forms, such as magnetite, lodestone, and hematite, and possess magnetic properties due to their composition of iron and other elements.
Is zirconium metal or nonmetal?
